High fuel consumption VAZ 2106 carburetor causes and solutions instructions with photos and videos

Practical recommendations for optimizing fuel consumption in a VAZ 2106 car

In the early 70s of the last century, the VAZ 2106 met all the requirements of the technical regulations for middle-class cars in terms of parameters such as specific power and fuel consumption.
Today, although power units are obsolete, they continue to operate on a huge number of cars that are still in use in our country and abroad. The recent unsatisfying price of liquid automobile fuel forces owners to either switch to gas or look for ways to reduce fuel consumption.

What is the fuel consumption of the Lada and how to reduce it

For Lada, like other cars, the average fuel consumption of the VAZ 21061 on the highway is about a quarter more than in the city. Such features are due to the fact that on the highway cars quickly adapt to speed, stable driving, without sudden braking and other things.

It is worth saying that car maintenance now is not cheap, and therefore many motorists are thinking about how to reduce fuel consumption on a VAZ 2106? This question has remained relevant since the time when the first car appeared. For a long time, drivers have come up with a lot of ways, and yet, they were able to find several that work. Before moving on to them, you should understand that saving is not a modification of your car, but rather a change in your behavior and driving habits.

Several ways to reduce car fuel consumption

• Change the way you drive your car, don’t try to push it to the maximum. The manners of a real driver are characterized by: smoothness, accuracy, absence of sudden braking and starting. Using a VAZ at medium engine speeds is the most effective way to save gasoline.
• Correct all breakdowns in a timely manner. Any damage to the car provokes an increase in fuel consumption, which is not savings. Ultimately, a minor malfunction can lead to a number of problems, and then you will have to empty your piggy bank completely! Speaking about the fuel consumption of the VAZ 2106, this car simply brutally consumes its fuel reserve when it breaks down.
• Don't skimp on the quality of gasoline. Low-quality gasoline will not allow the “horse” to work well; it will clog the existing filters, which will not only reduce the machine’s power significantly, but will also lead to a lot of breakdowns in the future. Unfortunately, such savings often become the cause of malfunctions.
• When choosing a car, you should consider what class of car you are able to service efficiently and quickly; initially, you should not consider any car. Give preference to those cars in which you are completely confident, because your “horse” should run and not sit in the garage. If you can’t afford a car with high fuel consumption, give preference to small cars!
• The last method is the most dangerous for your car unless you are a professional or a mechanic. Tuning the carburetor allows you to reduce fuel consumption, but at the same time you need to be prepared for the fact that the performance of the VAZ may also decrease.

Main factors influencing increased fuel consumption

The amount of fuel burned by a car is influenced by many reasons, both independent of the driver and predetermined by his attitude towards his car and the nature of his driving. Let's consider the main reasons causing increased fuel consumption of the VAZ 2106.

Season. It's no secret that in the cold season a considerable amount of fuel is spent on warming up the engine before a trip, as well as during stops and parking. When traveling in winter, the vehicle's heating systems must be turned on at all times, as well as headlights turned on during the daytime in some countries. This increases the load on the generator and, accordingly, on the power unit. Therefore, the fuel consumption of the VAZ 2106 in winter increases significantly. In summer, additional fans are also required to blow the engine radiator and ventilate the cabin.

Car load level. Everything is clear here: the more the car is loaded, the more work needs to be done to move the additional mass. From the physics course we know that all work requires energy. This results in additional waste of fuel. Sometimes you can reduce the fuel consumption of a VAZ 2106 by even emptying the trunk of your car of unnecessary things.

Driving style and road conditions. Prolonged driving in low gears increases gas mileage. This is also affected by sudden acceleration and immediate braking, as well as aggressive driving. And if the driver can influence these factors in the most direct way, then it is impossible to influence the condition of roads. We can only recommend choosing a route based on considerations of the quality of the road surface and traffic safety.

Aerodynamic resistance. It should not be forgotten that even large external rear-view mirrors can increase the fuel consumption of VAZ 2106 cars by up to 0.5 liters per 100 km of vehicle mileage, not to mention a roof rack filled with bulky items.

Condition of automotive systems and assemblies. This is the most important factor influencing the VAZ 2106, whose high fuel consumption worries the owner. After all, it is not news that a properly configured and adjusted engine, as well as serviceable components and assemblies of the car, will allow it to meet the consumption standards established by the factory. It must be recalled that for the VAZ 2106, fuel consumption is 7.4 liters per 100 km when driving along the highway at a speed of 90 km/h.

How to reduce gasoline consumption VAZ-2106: profitable saving options

Gasoline today is not cheap, so it is natural that car owners strive to reduce its consumption.

Here are some smart and effective ways to save fuel:

1. One of the most effective options is to install gas equipment. Propane and methane are cheaper than gasoline.
2. Change your driving style. In the city you can drive at a speed of 60 km/h, and on the highway – 90 km/h. You should forget about sudden acceleration and braking. As a rule, this helps reduce fuel consumption by 40%.
3. Installing a pneumatic drive on a carburetor.
4. Installation of a 5-speed gearbox.
5. Use light motor oils. It is advisable to use oils with low viscosity, as they save fuel by 6%.
6. Check tire pressure periodically. If the ramps are underinflated, they increase rolling resistance, which, in turn, significantly consumes fuel. Please note that the check can only be carried out with cold tires.
7. Maintain approximately the same speed, even in traffic jams. As we said, you shouldn't brake and start hard if you want to reduce fuel consumption.
8. Use the pedal carefully. A sudden start consumes a lot of fuel, so you need to start the car slowly.
9. Rarely turn on the air conditioner. This device burns from 5 to 20% gasoline.
10. Get rid of anything that increases air resistance. This is mainly due to tuning, extra things in the trunk, cargo on the roof, etc. It is also advisable not to change the serial wheels to wide ones.

The following actions will also help save fuel consumption:

• Only when absolutely necessary should you use power windows, heated rear windows and interior lighting. By and large, these devices are rarely needed, so their use can be reduced;
• replace contact ignition with electronic one. In most cases, this helps reduce fuel consumption;
• troubleshoot problems in the ignition system in a timely manner. Approximately 30-40% of fuel can be lost if the ignition system operates intermittently;
• Do not brake suddenly. In particular, this applies to carburetor cars, because during sudden braking, a large amount of fuel is sucked through the jets.

So, we looked at the most effective and popular ways to save gasoline. If you are used to driving at high speeds, you will have to forget about this in order to save money. It is also important to follow a number of other rules in order to reduce fuel consumption in your car. It is very important to act without fanaticism, otherwise saving will not lead to anything good.

Ways to reduce fuel consumption on the VAZ 2106

The very first thing is to reduce the amplitude and frequency when pressing the accelerator pedal. With each press, the carburetor accelerator pump injects about 1 ml of gasoline into the secondary chamber. You should adhere to a smooth ride, with a smooth start from a standstill and leisurely acceleration. It is also necessary to brake gently, assessing and predicting the road situation in advance and slowing down long before the car stops.

It is necessary to strictly follow the manufacturer's requirements regarding the degree of load of the car and not allow it to be overloaded. When planning your trip, decide whether you need a roof rack and remove it if you don't need it.

If fuel consumption has increased, pay close attention to the following factors regarding the condition and adjustments of the engine:

• set the ignition timing correctly (an incorrect ignition timing can cause overconsumption of up to 15%);
• change the air filter in a timely manner (with a clogged filter, the engine will run on a rich mixture);
• use good oils with minimal viscosity characteristics from trusted manufacturers;
• change the oil and oil filter promptly;
• The carburetor has a huge impact on fuel consumption, so adjust it (adjust the fuel level in the float chamber, eliminate the overflow of the accelerator pump, set the opening moment of the secondary chamber flap);
• adjust the ignition distributor according to the tachometer (ignition timing when increasing engine speed must meet factory requirements);
• adjust the clearances in the valve mechanism;
• measure the compression in the engine cylinders and repair it if necessary.

If you correctly adjust the VAZ 2106 engine, fuel consumption should decrease and meet the norm. Additionally, check the wheel alignment angles, tire condition and tire pressure. Love your car, maintain it on time, and drive calmly. Surprise yourself and your friends with low fuel consumption when traveling in this popular car.

Diagnosis and resolution of technical problems

A serious increase in fuel consumption never occurs without reason. The “culprit” is often detected by the following signs:

• Features of adjustment and tuning of VAZ-2106 carburetors

• drop in engine power, noticeable deterioration in traction and acceleration dynamics;
• the appearance of the smell of gasoline in the car interior;
• idle failure;
• jerks and dips during movement;
• the engine suddenly stalls while driving;
• at idle, the crankshaft speed “floats”;
• The smell of burnt pads and noise from increased friction can be heard from the wheels.

The listed symptoms may indicate one or more technical problems. To save fuel, learn to quickly recognize the source of a malfunction and promptly fix the problem - yourself or at a service station.

Cylinder piston and valve group

Natural wear of pistons and rings causes the following consequences:

1. A gap is formed between the walls of the cylinders and pistons, into which gases from the combustion chamber penetrate. Passing through the crankcase, exhaust gases are sent through the ventilation system for afterburning, contaminating the carburetor air jets and excessively enriching the fuel mixture. Gases penetrate through the gap around the worn piston, and the compression of the combustible mixture deteriorates
2. Compression drops and gasoline combustion conditions worsen. To develop the required power, the engine begins to consume more fuel, and the lion's share of unburned fuel is thrown out through the exhaust tract.
3. Motor oil penetrates into the combustion chambers, aggravating the situation. A layer of carbon deposits on the walls and electrodes causes overheating of the cylinder head.

Critical wear of the cylinder-piston group increases fuel consumption by 20-40%. Valve burnout leads to complete failure of the cylinder and an increase in flow rate by 25%. When 2 cylinders are switched off in a VAZ 2106 engine, gasoline losses reach 50%, and the car practically “does not move.”

A burnt-out valve allows gases to pass in both directions, the pressure drops to zero and the cylinder completely fails.

How to check the motor for wear:

1. Pay attention to the color of the exhaust - oil fumes produce thick bluish smoke.
2. Disconnect the crankcase ventilation pipe from the air filter housing and start the engine. If the compression rings are worn out, a bluish exhaust will come out of the hose.
3. Measure compression in all cylinders while hot. The minimum acceptable value is 8.5-9 Bar.
4. If the pressure gauge shows 1-3 bar pressure in the cylinder, the valve (or several valves) has become unusable.

Thick, bluish-colored exhaust indicates waste of engine oil and wear of the piston group.

To finally make sure that the valve is burned out, pour 10 ml of motor lubricant inside the cylinder and repeat the compression measurement. If the pressure rises, change the rings and pistons; if the pressure remains unchanged, throw away the valves.

Zero readings on the pressure gauge indicate a leak in the cylinder due to a burnt-out valve.

The wear of elements and the “gluttony” of the engine can be treated in the only way - major repairs and replacement of unusable parts. The final verdict is made after disassembling the power unit - perhaps it will be possible to save money by changing only the valves and rings.

Fuel supply system

Problems in this group cause excess fuel consumption of 10-30%, depending on the specific problem. The most common breakdowns:

• Engine 2106 - the fourth generation of VAZ engines

• increased fuel level in the carburetor float chamber;
• clogging of air jets (one of the reasons is stated above);
• abrasion of the throttle valves - gaps form at the edges, from where the engine sucks in fuel due to vacuum;
• unqualified carburetor adjustment - violation of the settings of the support and fuel screws;
• air leaks on the intake manifold flange or on the throttle valve axles;
• breakthrough of the lower diaphragm of the fuel pump.

If the car interior smells like gasoline: https://bumper.guru/klassicheskie-modeli-vaz/poleznoe/zapah-benzina-v-salone.html

The last malfunction is the most insidious. The pump pumps fuel in 2 directions - to the carburetor and into the engine crankcase through the drive rod. The oil dilutes, the pressure drops, gasoline vapors fill the intake manifold and greatly enrich the mixture, consumption increases by 10-15%. How to detect: remove the breather tube with the engine running and carefully sniff the gases. A strong smell of fuel will immediately indicate a malfunction.

If there is gasoline in the crankcase, smoke with a pungent odor will come out of the removed pipe.

Another way to check the carburetor is to tighten the “quality” screw with the engine running. Turn the regulator with a screwdriver and count the revolutions - at the end the engine should stall. If the power unit continues to operate with the screw tightened, it means that fuel enters the manifold directly. The carburetor must be removed, cleaned and adjusted.

If the “six” engine stalls safely, turn the screw back to the calculated number of revolutions

Do not try to save money by replacing standard carburetor jets with parts with a smaller flow area. The fuel mixture will become lean, the car will lose dynamics and power. You will increase your consumption yourself - you will begin to press the accelerator pedal more intensely.

Replacing the fuel pump membrane is not difficult:

1. Disconnect the fuel hoses.
2. Unscrew the 2 fastening nuts with a 13 mm wrench. The Zhiguli fuel pump is screwed to the flange on the left side of the engine (in the direction of travel)
3. Remove the pump from the studs and unscrew the housing with a screwdriver.
4. Install 3 new membranes, assemble the unit and attach to the engine flange, replacing the cardboard gasket. The VAZ 2106 gasoline pump has 3 membranes, they are always replaced together

Ignition elements

Problems in the spark generation system also cause the power unit to consume excess fuel. Example: due to misfire, a portion of the combustible mixture drawn by the piston into the combustion chamber completely flies out into the pipe during the next cycle. There was no flash, no work was done, gasoline was wasted.

Common ignition system problems that cause excessive fuel consumption:

1. Failure of a spark plug leads to cylinder failure - plus 25% to fuel consumption.
2. A breakdown of the insulation of high-voltage wires reduces the power of the spark, and the air-fuel mixture does not burn completely. The residues are pushed into the exhaust system manifold, where they can burn out without any benefit to the engine (popping noises are heard in the pipe).
3. Sparking worsens due to malfunctions of the distributor parts - breakdown of the cover, burnout of the contact group, wear of the bearing. The mechanical contact group must be periodically cleaned and the gap adjusted to 0.4 mm
4. When the membrane of the vacuum unit becomes unusable or the springs of the centrifugal regulator weaken, the ignition timing decreases. The spark is supplied late, engine power drops, and fuel consumption increases by 5-10%.

You should not remove the armor wire with your bare hands - put on a glove or use pliers

• Fuel consumption of the VAZ 2107: what it depends on and how to reduce it

The best diagnostic method for an inexperienced driver is to replace the distributor or high-voltage cables. If there is no spare distributor in the garage, clean or change the contact group - the spare part is inexpensive. Bearing play is checked manually by rocking the turntable up and down. Diagnose the integrity of the vacuum unit membrane by drawing air through the tube leading to the carburetor.

VAZ 2106 1.3 MT 64hp

Fuel consumption rate per 100 km

The model with this installation went all the way from the very start in 1976 to its removal from the assembly line in 1993. It is worth noting that for that Soviet period, the “six” was the embodiment of fashion. Especially considering the lack of imported competitors. The model consumes only gasoline and works exclusively with a 4-speed manual transmission. At the same time, the consumption cannot be called minimal. In the city, the VAZ consumes 9.5 liters, and on the highway - 7.6 liters. The maximum speed is only 145 km per hour. Naturally, acceleration to hundreds is corresponding - 18 seconds.

Real gas consumption

• Anton, Kirov. I got a 1992 1.3 liter device. Of course, there were few original spare parts in this “six”, but the engine did not let down. If you don’t tear it along the highway and warm it up every time in the winter, then it will serve faithfully for decades. By the way, consumption in this case will not be brutal either - up to 10 liters in the city and about 7 on the highway.
• Nikolai, Adler. For a long time there was a VAZ 2106 '85. And even though one and a half liters is more modern, 1.3 also shows good data. I drove this car, and I can tell you its fuel consumption down to hundredths. On average, in a free city I spent about 8.5 liters.
• Sergey, Ulyanovsk. The ’88 “Six” came to me in 2005 and served for another 5 years before being sold. I didn't particularly complain about the consumption. True, sometimes I had to drive with a stove even in the summer so that the engine would not get hot in traffic jams. So she takes her 10 AI 92.
• Mikhail, Tomsk. A very warm car. And it doesn’t matter how much volume is under the hood. Personally, I had a 1.3 liter 1994 model. The interior was completely warmed up in winter in just 9 minutes. But consumption in cold weather is about 9.5-10 liters.
• Oleg, Nizhnekamsk. I bought a new 1.3 MT in 2001. I drove it for almost 6 years and never complained about the engine. But he treated her like a family member. I changed the consumables myself, and sometimes even ahead of schedule. Well, the appetite of the “six” is not the smallest. I rarely left the city, so I filled it with 10 liters. per hundred.

Technical characteristics of Lada

If we talk specifically about the VAZ 2106, then this car fully corresponds to its price category, it is equipped with everything necessary, and has an attractive design.

The VAZ 2106's gasoline consumption per 100 km is low, about 7 liters on the highway, and about 10 liters in the city

. This is normal consumption for a car with such power, but it is worth noting that such fuel consumption of 2106 per 100 km is beyond the means of many car enthusiasts.

To avoid problems with servicing your VAZ 2106, you should pay attention to some things even when purchasing it:

• The price of the car itself;
• The approximate price you are willing to spend on its maintenance per year;
• Approximate cost of gasoline for a car per month;
• Unplanned capital investments;

Only by calculating the approximate costs of it for a year, and correlating it with your capabilities, can you determine your chances of properly servicing such a car.

Fuel consumption on a carburetor VAZ 2106 also does not exceed the norm, and is not particularly different from the usual consumption of this VAZ, because the volume of gasoline burned can fluctuate, depending on many factors: weather conditions, the condition of the car, driving habits, the quality of gasoline and oil.

Only after consulting with them, you will be able to make the right decision, or, perhaps, you will be insured against unpleasant situations and possible breakdowns.

VAZ 2106 1.6 MT 75hp

Since 1976, the car in this configuration has traveled across the vast expanses of the Union, and then the CIS. This unit is the most powerful carburetor unit in the entire line. In terms of bodywork, this version is completely no different from other versions. The motor has a larger volume and, accordingly, better performance. Production of this type stopped in 2006. In terms of consumption, the unit is not much different from the version with a volume of 1.3. In the city, 10.1 liters are consumed, and on the highway – 7.4 liters. The engine is powered by gasoline and works in tandem only with a manual gearbox. Maximum acceleration is up to 150 km per hour.

• Alexander, Alapaevsk. I recently bought myself a 2002 version 1.6 MT. I accelerated it to 160 km/h, so the official data lies a little. But in terms of consumption everything is accurate. In a mixed cycle, less than 10 liters does not come out. Usually I fill the tank with 20 and for 190-200 km it’s enough for me.
• Alexey, Ivanovo. I drove a 1.6 1996 for about 3 years. After that I made capital. By the way, consumption dropped slightly after the repair. Now sometimes it’s possible to get even beyond 8 liters per hundred. But this is only on a smooth highway.
• Evgeniy, Moscow. My “six” ate gasoline and oil in half. I really didn’t want to repair the engine, but apparently the time has come. If you don't take this cap into account. repair, the engine is not capricious and pulls well even when the car is full to capacity. On the highway, according to the passport, it took 7.5 liters.
• Sergey, Sarov. In the 90s this was my salvation. I took the 1991 model. and always repaired it myself. I didn’t even touch the engine, I only managed to change the oil and spark plugs. And he always thanked me for his precise work, drove the car, and lived on this money. I must say that the 1.6 engine did not rob me. I count 10 liters. per 100 km is a very small figure.
• Dmitry, Cheboksary. During the time I used (1990-1995) the “six” 1.6 I managed to change two boxes, 2 batteries and many other small things. But the engine withstood the service staunchly. In other words, this is the most reliable unit in the 2106. It didn’t tear on the highway, and it only consumed about 7 liters.

The VAZ 2106 as a car model has lived too long of a life. But these “workhorses” will roam the expanses of Eastern Europe for a long time to come. Although they are outdated, their simplicity and ease of repair allow them to compete with modern and technically advanced competitors.

Eats 9-10l, on 4 mortar

From personal experience I will say this, on Solex it will be faster. What about the expense? As you press your slippers, so will you eat. And to reduce consumption, take a 5x5 wooden block and place it under the accelerator pedal. The thicker the bar, the lower the consumption. Gee

There is an option, walk)

Nope) Even though she eats a little too much, I won’t leave my car)

Solex will only increase consumption, just show the machine to a good specialist (usually older, experienced men) who have normal Soviet jets, repair kits, and so on, because there is nothing to take from new ones. Of course, they won’t reduce your consumption by half, but they will help significantly.

I went to the best carburetor in town. He said it definitely wouldn’t be less than 11, since the sixes from the factory had a consumption of 10.6 per hundred square meters without warming up.

Well then, yes, this is kind of a normal expense. There are simply examples with a consumption of 20, or even 25 and 30. Those who ask what to do and climb into the carb with their own hands.

wow, it’s scary to imagine such consumption on a Lada) Of course, many people advise using gas, but I am a supporter of the fact that gas still has a negative effect on the engine.

Perhaps the second generation has a detrimental effect on the engine, but the 4th does not (such a generation does not shine for VAZ). The main thing is to correctly adjust the OZ and everything will be fine. Because the burning speed of propane and gasoline is different. And even when warming up, the engine still runs on gasoline. Five minutes on gasoline is enough. And on the 4th generation, a tiny amount of gasoline is mixed into the gas. So don't be afraid of gas. If you travel a lot, of course.

I'll think about it in my spare time)

wow, it’s scary to imagine such consumption on a Lada) Of course, many people advise using gas, but I am a supporter of the fact that gas still has a negative effect on the engine.

I had a consumption when, for the sake of experiment, I decided to remove the spring of the pneumatic drive of the second chamber, the car drove much better, but the consumption was 15 liters per 30-45 km)))

Haha with such a consumption under the hood the engine should stand at 5 liters)

wow, it’s scary to imagine such consumption on a Lada) Of course, many people advise using gas, but I am a supporter of the fact that gas still has a negative effect on the engine.

Have mercy on the car. Fuck this gas! If you are not satisfied with the consumption, take a foreign car. In my city it’s 5-5.5. There is no point in hoping that the Lada Ludet is like a good foreign car.

I thought I definitely won’t install gas)

On gas, all dvieks sneeze like sick people. I just feel sorry for them.

Well then, yes, this is kind of a normal expense. There are simply examples with a consumption of 20, or even 25 and 30. Those who ask what to do and climb into the carb with their own hands.

Well, that's fairy tales already

I went to the best carburetor in town. He said it definitely wouldn’t be less than 11, since the sixes from the factory had a consumption of 10.6 per hundred square meters without warming up.

It’s not true, the carburetor man lied, for sixes with a 1.6 engine, according to the passport, the consumption on the highway is 8 per hundred square meters with a quiet ride (on the highway 90-100). On mine, with the original OZONE carb, this was the case. Then I installed Solex 21073, the consumption was within the same limits, now it is Solex 21053-62, the consumption is 7-7.5. Consumption of 10 liters can only be achieved in the city, when you accelerate from traffic light to traffic light and are stuck in traffic jams.

VAZ fuel consumption.

VAZ fuel consumption is always acceptable. The developers are seriously thinking about reducing fuel consumption for different VAZ brands.

VAZ cars are domestically produced cars. VAZ is a Volga automobile plant, it is located in the Samara region in the city of Tolyatti. VAZ cars are distinguished by moderate fuel consumption and affordable prices.

Data on VAZ fuel consumption are described below in the table on fuel consumption of VAZ cars. VAZ cars are not only a means of transportation, but also an integral part of everyday human life.

Fuel consumption of a VAZ depends on its modification (brand), driving style and time of year. The table below shows the average fuel consumption of the VAZ brands of the 2107, 2114, 2110, 2106, 2112, 2109, 2115 family.

Do not overload the vehicle's on-board network

Rationale : remember that the mandatory low beam alone “eats” more than a liter of gasoline for every 1000 km of travel. Therefore, try to save on winter trips at night. Heater, heated rear window, engine cooling fan - everything increases fuel consumption. For example, when standing closely in traffic jams, the low beams can be turned off and turned on when moving.

A rare button turns on in vain. It is much more important to turn it off in time. Getting carried away, they forget to turn off the heated rear window.

Disadvantages : do not get carried away with this advice in cold weather, it can reduce visibility and create an emergency situation.

Table of fuel costs for VAZ brands.

The table describes the average costs for different VAZ brands . Fuel consumption is presented in three types - city, highway and mixed (average) fuel consumption. All data on fuel costs are from the VAZ car manufacturer. For almost all brands of VAZ cars, fuel consumption does not exceed 10 liters per 100 km, with the exception of the carburetor Niva.

Average fuel consumption VAZ

liter/100 km

120 km/h=10

120 km/h=9.8

VAZ has acceptable fuel consumption!

The car is given good dynamics and acceptable fuel consumption thanks to its reliable engine. VAZ has an affordable price for both a new and an old car. Old VAZ brands are acceptable to most people. The new VAZ engine demonstrates extreme efficiency, thanks to which the car has low fuel consumption and a reduced level of harmful emissions into the atmosphere.

VAZ - average quality cars, affordable price and acceptable fuel consumption.

What could cause increased consumption at VAZ?

1. Increased VAZ fuel consumption is observed in cars with a worn out engine. High piston wear will increase fuel consumption of any VAZ brand. Wear is determined by measuring compression in the VAZ engine block. If the compression is low, the piston needs to be replaced (rings, piston, block boring).

2. The increased flow rate is influenced by the coolant temperature, throttle position, mass air flow and detonation sensors.

3. High fuel consumption in VAZ cars is observed when the accelerator drive is faulty, the wheel alignment is adjusted correctly, or tire pressure is reduced.

4. An increase in fuel consumption in VAZ cars with carburetor engines is observed when there is a problem with the carburetor. These are holes in the diaphragms, incorrect adjustment of the choke cable, enlarged fuel jets, mixing up of air jets in two working chambers (chamber 1 = 165 mm, chamber 2 = 125 mm).

Timely completion of technical inspection will allow VAZ to maintain fuel consumption at the level declared by the manufacturer.

Condition of the internal combustion engine and fuel system

If the engine of your VAZ 2106 is already pretty tired, and the mileage without repair is already hundreds of thousands of kilometers, then it is possible that the reason for the increased fuel consumption is precisely the loss of engine power.
And moreover, it begins to consume excessively not only gasoline, but also oil. In this case, only engine repair will help solve this problem: replacing the piston rings, boring the cylinders if necessary, and replacing the pistons themselves.

Regarding the fuel system, we can also say that it must be in excellent condition in order for consumption to remain normal. The carburetor should not “flood” or over-supply fuel at idle speed. Adjust the carburetor if necessary.

If you somehow have an injection engine installed, then the increased consumption may depend on even larger factors. For example, the failure of one of the ECM sensors almost always entails an increase in the appetite of your car. This is especially true for sensors such as mass air flow sensor (MAF) - mass air flow sensor, TPS - throttle position sensor, IAC - idle air control and others...

Principles of fuel consumption for a VAZ 2106 car

In standard VAZ 2106 models, fuel consumption is carried out according to the classical scheme. The main part in the fuel supply system is the carburetor. The “six” can be considered one of the typical representatives of carburetor cars.

One of the indicators of stable operation of a machine is fuel consumption. Car enthusiasts note different indicators of this value, depending on the season, driving characteristics, and load on the car. But these are deviations within the normal range, acceptable and understandable. An increase in fuel consumption entails additional costs for maintaining the car. What are the reasons for the increase in fuel consumption by the VAZ “six” and whether they can be significantly reduced - these questions are pressing for owners of cars of this brand.

Fuel quality and octane number

I think many people have noticed that depending on the place of refueling, your VAZ 2106 always consumes gasoline differently.
If this has not been noticed, it means you haven’t been driving long enough yet. Everyone encounters low-quality gasoline in one way or another. Another question is how to protect yourself from this? Well, it’s difficult to give any sensible advice here. Unless you try, if possible, to refuel only in trusted places. But even there, there is outright slag! If you feel that there is surrogate in the tank, then ideally you need to drain all this crap and refuel with normal fuel. Otherwise, you risk damaging the engine.

Regarding the octane number. Here you should follow the manufacturer’s recommendations and fill in the gasoline that your engine requires. If it says 92, then be so kind as to only pour it if you want normal consumption.

Fuel supply diagram

To find out the reasons for the excessive consumption of the fuel mixture, you should understand how the fuel supply system of the 2106 car is designed. The gas tank in the six is ​​located in the luggage compartment, fixed and separated by a plastic partition. The tank is equipped with a neck for filling gasoline; it is brought out through the hatch of the rear right wing and sealed to prevent the penetration of dust and dirt particles into the tank.

To regulate the pressure of gasoline and air vapors, the gas tank is equipped with a plastic ventilation pipeline laid in a loop. The gasoline level indicator is fixed through a rubber gasket. This rheostat-type sensor is located on a flange, which is welded to the top of the tank. The sensor is a block element with a tube (fuel intake) with a mesh filter at the end. Changing the level of the fuel mixture causes the float-shaped sensor to start moving, changing the resistance of the rheostat. Because of this, the current that the sensor-pointer system passes through changes, and, accordingly, the pointer (arrow) moves.

The pipeline, consisting of special rubber in a fabric weave, is fastened and fixed to the fuel line. All holes for hoses or tubes are hermetically sealed with rubber bushings. To gently clean gasoline, a filter is placed in front of the pump. The power system cannot do without this filter, which retains mechanical particles and cleans the mixture to the required level. Other filters that contain the pump, gas tank or carburetor cannot cope with such tiny fragments. A mechanically driven fuel pump (diaphragm type) creates excess pressure and injects the fuel mixture into the carburetor.

Located to the left of the engine cylinder block, it also has a manual fuel pumping lever. The carburetor produces the desired composition of the air-fuel mixture and regulates its intake into the engine cylinders. The carburetor is controlled from the driver's seat using the accelerator pedal; it is connected to the drive lever of the first carburetor chamber by a system of rods and hinges.

Carburetors on VAZ models are of two types - “ozone” and “weber”.

Common “myths” about fuel economy

The tips listed above are simple and straightforward. Some relate to driving style, some require car monitoring, some require timely replacement of parts. But they all mean that the driver needs to do something while driving and “turn on his head.” But there is a whole category of “magic” advice that all work according to the same scheme. Here she is:

• The driver does not need to do anything. Fuel economy occurs “by itself”;
• There is a super-secret technology (military, foreign, NASA, local craftsmen, unrecognized geniuses, a forgotten patent - there are many options);
• Based on it, a completely unique device has been created that is mounted on a car (in the power supply system, exhaust gas removal system, anywhere);
• The device costs significant money, and tangible savings are revealed after a few weeks (months). Moreover, the savings are incomparable with all the above tips - they are simply not needed;
• A large number of seals, certificates, a completely incomprehensible explanation of the principle of operation, but inspiring respect due to the complex use of a mass of scientific terms;
• A huge number of grateful reviews on the site, without a return address or mail.
• A widespread option are various secret fuel additives, “ metal conditioners,” and so on.

There are “specialists” who install pyramids , which use “torsion bars” to reduce gasoline consumption.

For example, you can read rave reviews about GEET - muffler , or centrifugal muffler, which “saves” up to 30% of fuel, which is installed as close as possible to the exhaust manifold. Essentially, we are talking about removing the catalyst (which results in an increase in power), and injecting a foreign liquid containing water into the cylinder.

The arsenal of such “means” is very large: cavitators, fuel ionizers that create “separate ion fields,” special fuel “magnets” that “split” the fuel in advance by the force of a magnetic field. There are “ miracle candles ”, air ozonizers for better oxidation and combustion of the mixture, and even “miracle tablets”, “nanofilms”

The height of convenience for lazy people is a “miracle” that doesn’t even need to be installed - just plug it into the cigarette lighter - and you’re in the dark, 20-30% of your fuel is for nothing. This is a large group of fuel “ economizers ”.

Remember, there is not a single link in the process of converting fuel into mechanical energy where scammers do not “suck in”.

In conclusion, we will let the reader choose for himself those methods that can save his finances and not end up in the fool. However, there is another way to save fuel, which is superior to all others in efficiency and is absolutely honest.

This is a way to weigh the need for each trip and make them in extreme cases : going with elderly parents to the dacha, going with the family on vacation, going to the market for heavy shopping. If you work within an hour's walking distance of an office and spend that hour (or even two) back and forth every day sitting in a car in traffic jams, instead of getting on your bike and covering the distance in 20 minutes, think about this advice.

The main reasons for the increase in fuel mixture consumption

When increasing gasoline consumption when driving, the VAZ owner needs to pay attention to the following points.

1. Possible fuel leaks - check the fuel system, the fuel line under the car, the condition of the clamps, whether the gas tank is sealed.
2. Clean the carburetor jets.
3. Check (and if necessary, change) the filter element on the carburetor air filter.
4. Monitor the correct idle speed control and adjust the mixture quality screw.
5. Check the tank: the fuel level sensor (indicator) may be incorrectly adjusted or misaligned.
6. The engine is running on choke due to a malfunction of the air damper.
7. The cylinders of the piston group are worn out, which forces the car owner to use lower gears; which also entails overspending.
8. The power of the VAZ 2106 engine is reduced due to incorrectly set ignition timing.
9. The ignition distributor is broken (the vacuum regulator does not function).
10. The engine overheats - there is a reduced filling of the cylinders with a mixture and a decrease in power. In case of poor warm-up, there is also excessive consumption of gasoline, which is not completely burned in the engine, and loss of power.
11. Check the fuel pump, there is a possibility of a broken diaphragm.

The driver's driving style also causes increased gasoline costs: sharp and too frequent pressing of the brake pedal, constant driving in lower gears (for various reasons).

Practical recommendations

Fuel consumption is affected by:

• technical condition of the machine;
• operating features.

In order to achieve more economical consumption, it is necessary to promptly clean and replace certain components of the mechanism.

In particular, an increase in the amount of gasoline or gas consumed is often a sign that the engine has almost exhausted its resource. Wear of the cylinder-piston increases the gaps between the cylinder walls and the rings. Because of this, exhaust gases and the fuel-air mixture enter the piston space. For the same reason, compression in the cylinders drops. The warm air mixture cannot burn completely. Therefore, part of the mixture remains unused and simply flies out through the exhaust pipe. Engine wear affects its functioning. Because of this, the car accelerates poorly. The driver has to press the pedal harder to accelerate the car.

Taking all this into account, it is not difficult to conclude that in order to reduce gasoline or gas consumption, you must first diagnose the engine. You need to measure the compression, listen to whether the engine makes any unusual noises during operation. If worn components are found, they must be replaced.

Also, the consumption of gasoline or gas depends on the condition of the gas distribution mechanism. If carbon deposits that form on valve seats and edges are not promptly removed, this will lead to loss of compression due to a loose fit.

Cleaning the valves and, if necessary, repairing the cylinder head will significantly reduce gasoline/gas costs.

It is important to promptly diagnose the gas distribution mechanism and promptly replace worn parts

Fuel consumption also depends on the carburetor. If you install a contactless ignition system and a Solex carburetor, then this combination will reduce the amount of gasoline or gas consumed

It is very important to adjust the carburetor correctly. It will be possible to reduce consumption by installing jets with a reduced cross-section

However, this will lead to a decrease in the dynamics and power of the machine. After this adjustment you will have to forget about overtaking. It will be very difficult to accelerate such a car. Therefore, it is better to carry out adjustments without replacing the jets. It is necessary to adjust the carburetor in such a way as to achieve a “golden mean” between power and fuel consumption. If the carburetor is clogged and incorrectly adjusted, fuel dosing is disrupted. Therefore, regularly check the condition of the carburetor and wash it periodically.

Troubleshooting Gasoline Meter Problems

When driving a car on the highway, instrument indicators are the main thing the driver focuses on. Therefore, problems with the tank full indicator can lead to serious problems. To control the gasoline level, the tank has a fuel mixture level indicator. The gas tank of any VAZ car has a float indicator. It measures the voltage, and the indicator changes the value depending on the value of the fuel mixture.

When the gas tank is only five liters full, the light on the indicator turns on. If there is a malfunction or breakdown, the tank-indicator system does not work or fails. The initial stage of diagnosis consists of assessing the disorders.

To carry out diagnostics, remove the device and inspect it. If it is broken, you can replace it with a new one, or heat the broken area with a soldering iron. Sealant or epoxy will not help - gasoline corrodes these materials. Then they check the rheostat and the slider: if it is closed, then a new one is installed. Perhaps it is not pressed tightly, then it is shifted to the edge of the track, in this place the production of the rheostat is reduced.

To ensure that the device is working properly after these manipulations, check the resistance using an ohmmeter. If the indicators differ significantly from 345 Ohms, then you should simply replace the element with a new one.

Operation and gasoline consumption

The reasons for the high gasoline consumption of the VAZ-2106 also lie in operation. An aggressive driving style is not designed for economy. Sharp accelerations lead to significant waste of fuel.

Reasons for the high gasoline consumption of the VAZ-2106

To save money, you should switch to a calm style - with smooth presses on the gas pedal, approaching traffic lights in neutral, and performing maneuvers only when absolutely necessary.

You should also choose the right load on the engine, do not give increased speed, but run the engine a little “pull”.

It has been established that the speed of the VAZ-2106 power plant, at which the flow rate is most optimal, is in the range of 3000-5000 rpm. If you stick to this range as much as possible when driving, you will be able to reduce consumption, and significantly - up to 25%.

Music lovers will have to choose between music and gas mileage, especially for those who use significant audio equipment (subwoofer, large number of speakers). Heavy load on the on-board network affects consumption.

Trunk of VAZ-2106

Therefore, to save money while traveling, you should reduce the use of electrical appliances to the maximum (use only the most necessary - headlights, light and sound alarms).

Excess weight in a car means grams of fuel. Therefore, it is worth taking out the unnecessary things from the car and leaving the really useful things - tools, spare tire, etc.

Windows open while driving become a wind tunnel. That is, the air flow enters the cabin at high speed, thereby resisting movement. And the more the windows are open, the stronger the effect of the oncoming flow. Naturally, in the summer it is impossible to drive in a completely closed car (especially since there is no air conditioning in the VAZ-2106), but still, to save money, it is worth using the interior ventilation system (open deflectors), which, in general, are not very useful in the heat, but If you open the windows, then not all and not completely.

All these recommendations will not work a miracle, but they will not only allow you to return gasoline consumption to the established standard values, but also reduce it slightly (in some cases it is possible to reduce consumption to 6 liters on the highway).

Finally, we note that consumption is affected not only by the technical condition and operating features. Savings also largely depend on the fuel itself. If it is of poor quality and contains impurities, then much more of it will be consumed (it will not be able to burn fully, hence the drop in power and the need to press the gas pedal more to obtain the necessary driving dynamics). Therefore, refueling with high-quality fuel, even if it is a little more expensive, ultimately results in savings.

Remember that late ignition, incorrect electrode spacing and uneven, intermittent spark plug operation will increase fuel

by a few percent.
This figure may seem insignificant to you, but if you optimize the ignition, it can save you up to 10% of fuel
.

Monitor the temperature and condition of the engine. If the coolant temperature is lower than recommended by the manufacturer, fuel

increases by 10%, but much worse in this regard is driving on an insufficiently warmed up engine, which “eats” up to 20% of your
fuel
. Please note that wear on the engine cylinders and pistons reduces compression, and this in turn also leads to a significant increase your car's appetite: each missing compression unit will cost you 10%
of fuel
. Hence the rule: warm up the engine properly and monitor its condition if you want to save money.

Get things in order. The more you carry, the more fuel

it requires.
You should not travel with a year's supply of canned food in case of an emergency trip to the country; in the trunk and interior of the car there should be only the essentials: a spare tire, a jack, a first aid kit, a fire extinguisher, a set of the most necessary wrenches. Remember that every 100 kilograms of cargo will require an average of 10% gasoline in excess of the norm. The ideal order will allow you to save up to 30% of fuel
, which was wasted before harvesting.

Change all consumables on time. If you do not change air filters on time or use the wrong type of filter elements, this will cause the consumption of an additional 5%-10% of gasoline, and we already talked about the importance of maintaining spark plugs in order in step 1.

Fill with the correct fuel. If you drive on gasoline whose octane rating is lower than that prescribed by your car manufacturer, this may reduce the amount of your receipt at the gas station by some amount, but the consumption of such fuel

will be higher than normal by up to 50%! Truly: the miser pays twice.

Watch your driving style. This may be the most important thing you can do to reduce your fuel

. The less often you bother the gas pedal while driving, the less fuel your car consumes. We don't encourage you to drive at a snail's speed, just try to keep it constant for as long as possible. Don’t accelerate too much in vain, so as not to use aggressive, sharp braking, but at the same time, don’t slow down before each turn, otherwise your engine will then have to consume additional fuel to climb a hill or accelerate to normal speed.

What to do if fuel consumption in the VAZ-2114 has risen above normal? The factory documentation states that fuel consumption for this brand is 8.9-9.0 liters per “hundred” when driving around the city. In practice it turns out more. What actions should you take to reduce gasoline consumption? Below we will look at how to quickly and reliably achieve your goal.

Check the ECU

Increasing the “gluttony” of a car is not a reason to despair. The first thing to start with is to check the functionality of the fuel supply system. To solve the problem, understand the theoretical part. So, the ECM is an electronic system that controls the operation of the motor. This complex includes a group of nodes - the vehicle's ECU (electronic control unit), as well as sensors that collect information about the state of the nodes and transmit them for processing.

If any of the components malfunctions, the ECU displays an error, which is manifested by the “Check Engine” lamp lighting up on the dashboard. The difficulty is that the car owner only sees the fact of the problem. He cannot determine which part failed. To decrypt, special testers are used that read the code and provide complete information about the malfunction.

If the result confirms fears about the failure of the fuel system, carry out repair work and replace faulty components. Thanks to such actions, it is possible to reduce gasoline consumption and prevent more serious breakdowns. But what to do if all the indicators are normal, there are no error codes, and the sensors are working properly? In such a situation, start looking for another reason.

Study the technical characteristics and condition of the components

• First, check the air filter. If it is clogged or is due for replacement, install a new filter.
• Assess the condition of the spark plugs for contamination and the appearance of soot. If there are problems, clean the electrodes or replace the faulty element (about replacing spark plugs).
• Also check the ignition system wires. If the insulation is damaged or there is a spark breakdown to ground, repair the old ones or buy new wires.
• Now measure the compression and determine whether the valve timing is correct. An important point is the ignition timing, which, when properly adjusted, can also reduce gasoline consumption. The key parameter is the pressure in the fuel supply system. If it is reduced or increased, then this inevitably leads to increased “gluttony”.
• Pay attention to the injectors and check them for adequate flow rates.
• If the car is more than five years old, reflash the ECU (it is better to entrust the work to professionals).

What can really help reduce fuel consumption?

ON-BOARD COMPUTER

A useful thing for a car enthusiast is an on-board computer (Installing an on-board computer). The device, online, transmits the most important information for the driver - instantaneous fuel consumption, distance traveled, speed and other parameters. When you press hard on the gas, fuel consumption increases from 20 to 30 liters per “hundred”. Seeing such indicators on the display, you will definitely change your driving style. At the same time, it is possible to solve two problems - reduce gasoline consumption and make travel safer. Remember that aggressive driving, with a sharp increase in speed, increases the “gluttony” of the engine by an average of 20 percent.

DRIVING STYLE

The best driving option is to start smoothly, avoid sudden pressure on the gas pedal and avoid engine braking (the latter increases consumption by 3-5 percent). Also look at the engine warm-up sensor. If you start driving with a cold engine, fuel consumption increases by 10 percent.

TIRE PRESSURE

While operating the vehicle, monitor the tire pressure (). If this indicator decreases, pump up the tires. If the pressure is optimal, then add another 0.3 bar. In this case, the tire life increases and gasoline consumption is reduced.

ENGINE OIL QUALITY

Pay attention to the quality of the engine oil - it must have the required characteristics. Experts recommend using “semi-synthetic” from trusted manufacturers who value reputation. It has been proven that using good oil also reduces consumption.

What not to do

Many car owners, in pursuit of solidity and better cross-country ability, install wheels of greater width and height. As a result, rolling resistance increases, but fuel consumption also increases.

A popular way to save money for many is to buy gasoline with a low octane rating (contrary to the manufacturer’s recommendations). In such a situation, it will also not be possible to save money.

Practice has shown that the ratio of costs and mileage for the two types of fuel (AI-80 and AI-95) is approximately identical. At the same time, the use of low-quality fuel also reduces the service life of the engine. Therefore, filling the tank with bad or leaded gasoline is not recommended. If you take a risk, the ECU will detect incomplete combustion of the combustible mixture, which will increase the volume of fuel supplied to all cylinders.

About additives to reduce fuel consumption

Many car owners set the goal of reducing gasoline consumption at any cost. But the above actions do not always have an effect. The modern market is saturated with numerous additives, the addition of which to oil or fuel supposedly leads to savings. But such products can not only be ineffective, but also dangerous for the engine.

Today, additives are sold that are recommended to be added to gasoline, oil and the combustion chamber. In case of excessive engine wear, the use of such compounds can reduce friction, equalize compression in all cylinders and even increase engine power. But the main issue, which concerns reducing fuel consumption, cannot always be resolved. Using additives on a new or used engine is dangerous, because it often leads to the breakdown of an expensive component and the need for repair.

Another way to improve engine performance is to add special “power capsules” to the combustion chambers. According to the manufacturers, under the influence of high temperatures, the product melts and covers the metal surface of the piston with a protective layer. It is believed that such optimization leads to an increase in compression by 3-4 kg/sq. centimeter. In addition, the engine power increases (up to 15%) and its service life is extended by 2.4 times. It is also possible to reduce gasoline consumption by 17-21 percent. But remember that here you act at your own peril and risk.

Today, there are manufacturers producing coolant modifiers, the action of which is aimed at improving heat transfer and reducing the temperature of the walls of the combustion chamber. In addition, such products solve a number of other problems - they optimize heat transfer, restore thermal gaps, reduce fuel consumption and increase the volume of air in the incoming combustible mixture (this is achieved by reducing exhaust gases). The additive is added to the expansion tank through a special cap for adding coolant.

Some car owners decide to tune the throttle assembly - cutting special grooves in it. As a result, the composition of the incoming fuel is optimized and the pressure of the forced air flow increases. It is believed that this modification can reduce gasoline consumption by almost 20 percent. The downside is that the technique is new and not fully studied. For this reason, there are not many people who want to try it on themselves. And there are no positive reviews about the results yet.

A popular way to save on fuel is to add special additives (additives) to the engine oil. The action of the latter is aimed at reducing friction of moving engine elements and restoring worn elements. At the same time, the manufacturer creates additives based on ceramic reduction, nanotechnology and other things.

Results

Operating practice and common sense show that to really reduce gasoline consumption, simple manipulations are enough - timely replacement of consumables, adjusting the main parameters of the car (including circuit voltage, under different engine operating modes) and careful driving. At the same time, there is no need to make structural changes. If there is high fuel consumption, start by checking the system responsible for the fuel supply. Attention to the VAZ-2114 car and its proper operation is a guarantee of reliability and efficiency.

Many people believe that reducing gasoline consumption and avoiding excess consumption are the same thing. This is an incorrect comparison. Therefore, those who solve the problem of how to reduce fuel consumption on a VAZ (2105, 2106, 2107, 2109) need to understand all the intricacies.

Firstly, you should not trust yard technicians who are trying to reduce fuel consumption by installing various gaskets and modifiers. Some of them suggest installing a jet with a smaller hole diameter in the carburetor. Remember one important idea - if the car is well-oiled, then no additions will have any effect in terms of reducing fuel consumption. Even a new jet installed can reduce consumption by 3-4%, so is it worth it?

Each master has his own ways to reduce fuel consumption, as well as his own recommendations. By combining them into one list, you can get a kind of instruction that will help solve the problem of reducing consumption.

• You need to constantly check the air filter. It is through this that air enters the carburetor to enrich the fuel mixture with air. The less air, the higher the gasoline consumption. Checking the filter is not difficult - look at it in the sun or a light bulb. If the light does not pass through, it is better to replace it with a new one.
• It is best to fill the engine with light oils based on synthetics or semi-synthetics. They have a reduced viscosity, which means 6% fuel savings.
• Never drive on flat tires. It is this condition of the wheels that increases rolling resistance, and this guarantees overspending. Firstly, you need to pump air into the tires on cold wheels. Secondly, it is better to increase the pressure inside them by 0.3 bar. This, of course, will affect the suspension (the load will increase), but passengers will not notice this, the smoothness of the ride will be almost the same.
• When driving around the city, especially in traffic jams, maintain the same speed. By the way, try driving for several days at a speed of no more than 90 km/h. You will immediately feel that you have stopped at the gas station almost twice as often.
• Do not suddenly start moving the car. You must press the gas pedal carefully. A sudden start is a big overrun. The thing is that with a sharp start, a large amount of gasoline is immediately supplied to the engine. Firstly, this is already a large one-time expense. Secondly, it has a bad effect on the engine itself.
• You should also not brake sharply, especially for carburetor cars such as VAZ. In this case, fuel begins to be sucked in in large quantities through the idle jets.
• For those who don’t know, an air conditioner is a device that is powered by an engine shaft. Turning it on increases the load, and therefore increases gasoline consumption. This figure varies from 5% to 20%. So turn it on less often.
• Anything that will interfere with the movement of the car and create air resistance must be removed. This includes a top rack, tuning bells and whistles, and so on. This also includes the width of the wheels. It's better to leave the standard narrow ones. This will be especially noticeable on long trips.
• Be sure to check the ignition system. Its malfunctions can increase consumption by up to 30%. Such faults may include poor wiring or dirty spark plugs.
• Do not clutter your car or overload it. Empty the trunk of unnecessary items.
• You should not drive at high speeds, especially in the city, where you will have to stop at traffic lights and intersections all the time.

Distinctive features of the VAZ 2106 engine

The VAZ 2106 engine is a fairly successful modification of the previous version of the VAZ-2103 engine, during the creation of which modern technologies were used.

Manufacturers have set themselves the task of improving the finished part by any means:

1. The power was increased using the total effective volume of the engine. Particular attention was paid to improving the cylinder.
2. Such modifications influenced the appearance of the cylinder block 2106-1002011. Apart from the diameter, the presented motor design no longer has any distinctive features.
3. During the manufacturing process, specialists give an individual cylinder its own class. Today there are about five names that differ by one millimeter. They are assigned the following symbols - A, B, C, D and E. You can see the conditional class of the motor at the bottom of the base.
4. The main head of the motor block with the designation 21011-1005011-10 was left unchanged. To change the overall diameter of the cylinder, manufacturers had to use new gaskets.
5. Absolutely all standard and generally accepted pistons have many similar characteristics to each other. The presented engine is equipped with pistons from the 21011 engine, where the nominal diameter is 79 millimeters.
6. The new motor model has cylindrical holes, and the volumes have been improved several times. During operation in each individual area, absolutely all pistons will heat up gradually and evenly. This is how it was possible to compensate for possible thermal deformations. Manufacturers also placed temperature-control plates made of high-quality steel in the piston bosses.

How to increase the power of a VAZ 2106 engine and minimize all kinds of dynamic loads on the piston part of the engine? You need to pay attention to the presence of a hole that is intended only for the piston pins.

Spacious trunk and interior, clear controls. Everything is so simple that, it would seem, there is nothing to break here. Alas, there are problems, but I attribute them to being 20 years old. The car consumes 8 liters per 100 km.

With 1.5 engine

• Alexander, Lipetsk. VAZ-2106 satisfies all my needs - both in the family and at work. I bought it in 2005, in new condition. I've driven 166 thousand km, everything works stably, with a 1.5-liter engine you can achieve 8-9 liters.
• Yaroslav, Nizhny Novgorod. A good car, a worthy representative of the Soviet automobile industry. But I wouldn’t be upset if it had been taken off the production line during the USSR, and then I definitely wouldn’t have bought it. And so, I have a shah purely for the dacha and various household needs, that’s where it belongs. Consumption 8 l.
• Anton, St. Petersburg. I have a VAZ-2106 with a 1.5-liter unit. Quite a powerful and dynamic car. In addition, what helps the six accelerate quickly is not so much the engine as the lightweight design. I studied the model, consider the body of my shahi to be empty, without any security. Well, that's true, if you're being too picky. But the VAZ will work purely for the city. The car handles well in city traffic and never lags behind. And if anything can be piled up at traffic lights. The 1.6 engine consumes 8-9 liters per 100 km.

The engine starts with half a turn even in cold weather, and I also praise the energy-intensive chassis and the precise operation of the gearbox. The steering wheel is empty, although shortcomings in handling are noticeable only at high speeds. But I’m not afraid of this, since I mostly ride around the city. Average consumption is 9 liters per 100 km, I fill with 92nd gasoline.

With 1.6 engine

• Vasily, Irkutsk. Shah pleased me, a solid and unpretentious car, it pleases the eyes of me, my wife and our children. A good family car. There were no problems with installing child seats, everything was fine. Average consumption is 9-10 liters with a 1.6-liter engine.
• Svetlana, Novosibirsk. I like how the VAZ-2106 overcomes our broken roads, as if like a bulldozer. No speed bumps are scary for him. I have a 1.6-liter version, it consumes 9 liters/100 km.
• Andrey, Yaroslavl. The car is fire, I have a 1.6-liter modification. A six with such an engine is a very dynamic vehicle, capable of keeping up even with foreign cars, if, of course, you try hard. In addition, the car has great potential for tuning. I bought the car in 2006, in the last year of its production life. It's called successful. All the same, the car is worth the money, although until recently I doubted this bucket of bolts. A 1.6-liter engine with manual transmission consumes 9-10 liters in the city.
• Konstantin, Moscow region. I like the car, it’s a great option for traveling around the city and to the country. The mechanics and 1.6-liter engine work as they should, they have optimal acceleration dynamics. There is something similar in no other car for that kind of money. The six accelerates and brakes quickly, consumes 10 liters per hundred.
• Nikolay, St. Petersburg. A car for all occasions, equipped with a 1.6-liter gasoline engine, very modern by the standards of that time. But it is not entirely clear why the six were produced until 2006. And they bought it, including me. Oh, how I regretted it, oh, how I regretted it. Breakdowns are a dime a dozen, I no longer have time to go to the service station every time. Still, people are right when they say that it is better to service such cars in your own garage. The car consumes 10 liters per hundred.
• Sergey, Ryazan. I have owned the VAZ-2106 for five years now, and my husband and I drive comfortably. We have a seven with a 1.6-liter engine, a reliable and unpretentious car, with a mileage of 125 thousand km. Consumes 9-10 liters per 100 km.
• Alexey, Bryansk. I liked the six, I serve it myself. By the way, this is my first car. I made it a habit to check my car every morning before leaving. And as a result, no problems on the road. Consumption is 9 liters, under the hood is a 1.6-liter engine.
• Vitaly, Orenburg. A great car for the city, comfortable and soft. If you drive fast, there will be noticeable roll in corners, but this is not critical. In addition, the six is ​​designed for a quiet ride. At least I try not to exceed 70-80 km/h. A VAZ-2106 with a 1.6-liter engine consumes 10 liters. It is possible to fill with 92nd gasoline. I praise the car for its impenetrable suspension. Still, the chassis of the car is very durable, so to speak, for centuries. But the design and reliability of the car leave much to be desired.

With HBO (on gas)

• Andrey, Vologda region. I'm happy with the car, the car suits me in all respects. I have a gas version based on a 1.6-liter engine. The dynamics have disappeared a little, but this is not significant compared to the advantages that the ability to drive on gas brings. Consumption has remained almost unchanged and is 9-10 liters, but costs have been reduced by almost half. The car is used as a taxi.
• Dmitry, Tver region. The car is worth the money, I have a 1.6-liter version with gas equipment. Consumes 11 liters, and I think this is acceptable for this class, taking into account the age of the car.
• Oleg, Kaliningrad. My gas VAZ-2106 has covered 98 thousand miles. Everything seems to be fine, but the smell of gas in the cabin is annoying, especially when I press it to the floor. You have to open the windows, otherwise you might suffocate, no problem. Average consumption is 8-9 liters.
• Nina, Krasnodar region. This is my favorite car, an indispensable assistant in household matters. The gas 1.6-liter engine allows you to save money on the operation of the six. In the city the car consumes 8-10 liters.
• Oleg, Perm region. VAZ-2106 is a very unpretentious and durable city car, I bought it for working as a taxi. The car is from 2006 and I still drive it. Despite the mileage of 180 thousand km, I am satisfied with the car. It is easy to maintain, and many breakdowns can be solved even in the middle of the road, as long as you have the necessary set of tools at hand. I have a 1.5 liter version with gas. In the city you can keep within 10 liters, on the highway it turns out to be 7-8 liters per 100 km.

Outdated carburetor models of Zhiguli are not very economical. According to the passport specifications, the VAZ 2106 consumes 9–10 liters of A-92 gasoline per 100 km in the urban driving cycle. Real consumption, especially in winter, exceeds 11 liters. Since the price of fuel is constantly rising, the owner of the “six” is faced with the difficult task of minimizing fuel consumption by all available means.
