VAZ 2109 carburetor and injector fuel consumption per 100 km.

The production of the five-door hatchback VAZ-2109 began in 1987, three years after the appearance of the three-door version of the VAZ-2108. These two cars became a completely unique phenomenon for the Soviet automobile industry - first of all, with their front-wheel drive layout, modern design at that time and an improved interior compared to previous Zhiguli models. The VAZ-2109 was more popular because the five-door design was more convenient than the three-door one.

The production of a car of this model continued until 2004 in the Russian Federation and until 2011 in Ukraine - here the VAZ-21093 version was assembled from vehicle kits supplied to the country by AvtoVAZ. Currently, this model is replaced in production by the VAZ-2114 model.

VAZ-2109 1.1 carburetor

The VAZ-21091 model was equipped with a derated carburetor four-cylinder VAZ-21081 engine with a volume of 1.1 liters. It developed a power of 54 hp. and a torque of 79 Nm at 3600 rpm. The engine was paired with a 4-speed manual transmission, but production of this model did not last long - until 1991, since the engine power was clearly not enough.

Gasoline consumption VAZ-2109 1.1 carburetor per 100 km. Reviews

Yana, Odessa. My husband and I bought a VAZ-2109 with a 1.1 liter engine in 2013. At first we were surprised, we didn’t think there was such an engine, but it turned out that it was the original engine. The car was produced in 1990, but is in good condition and the engine is actually not as weak as it seems - there are four of us in the family plus a trailer - it drives fine. Consumption on the highway is about 5.5 liters, in the city – about 8.5 liters.
Vladimir, Kozlovsk. The engine is not original - after mine burned out, I had to replace the engine. I couldn’t find a 1.5 liter one from my family, but through friends I managed to get a 1100 cm3 engine. What can I say about the dynamics - there is none at all, acceleration is generally slow, it does not accelerate more than 100 km/h at all. But in operation it is quiet and economical - 8 liters in the city, 5.5-6.0 liters on the highway.

Reasons for increased costs

There are a number of factors that determine the fuel consumption of a UAZ. They can be divided into three groups, among which are those that depend on the owner himself, the faulty technical condition of the parts or the type of flammable liquid. The influence of the last factor has already been mentioned, so we will focus on others.

The car is not working properly

The average gasoline consumption of the VAZ 2109 per 100 km is significantly influenced by the factors of incorrect carburetor settings, stuck needle and fuel pump (increase by an average of 4 liters). An insufficiently warmed up engine increases consumption by another one and a half liters.

Driving method of VAZ owner

The fuel consumption of 2109 per 100 km is also affected by the owner’s driving style - the higher the speed of the SUV, the greater the volume of liquid leaving the tank. When you turn on the headlights, the overall consumption rate increases by 10 percent, and flat VAZ tires have the same effect.

When installing a trailer, gasoline consumption increases by another 60 percent.

VAZ-2109 1.3 carburetor

The base engine for the VAZ-2109 was the VAZ-2108 engine. This is an inline four-cylinder carburetor engine with a volume of 1289 cm3 and a power of 64 hp. and with a torque of 94 Nm. Initially, the engine was equipped with a 4-speed manual transmission, but later a more efficient 5-speed gearbox was installed for it. The model with this engine was in production until 1997.

Also produced in a small series was the VAZ-2109-91 model, equipped with a 1309 cm3 rotary piston engine. This engine developed a record 140 hp for that time. and a torque of 186 Nm, but it was too unreliable and whimsical, so production was curtailed in the early 1990s.

Fuel consumption VAZ-2109 1.3 carburetor per 100 km. Reviews

Dmitry, Pavlodar. Before my “nine” I had a “kopeck”. After that I wanted to buy a foreign car, but for the amount I had, I could only buy a piece of shit that was trashed. I found a car made in 2000, with a 1.3 liter carburetor. What can I say - I started repairing it literally 30 minutes after purchase, because the battery died. On the highway the consumption is about 7 liters, in the city – at least 8.5-9.0 liters.
Oleg, Novosibirsk. I bought a “nine” from a friend in 2011. She stood in the garage for almost three years, did not leave and did not start. He discounted it at a normal price, I took it for service and the master said that it was in export configuration - that’s why it was preserved in normal condition, even though it was manufactured in 1993. I did the repairs and after that it started working like clockwork. It starts with half a turn, consumption in the city is 7.5 liters, on the highway generally 5.5 liters. They’ve already offered to buy it more than once or twice, but for now I’ll go on my own.
Mikhail, Khanty-Mansiysk. I bought the car back in 2006 – and it was hard to call it a car. The box was completely destroyed, the engine was generally in the trunk, I’m generally silent about the wiring and everything else. But the body was in excellent condition, only the wings were overcooked. I completely silenced it, gave the engine a major overhaul, and replaced the gearbox with a five-speed gearbox - by the way, a 5-speed manual transmission is completely useless for it, because... It still doesn’t go more than 130 km/h. But for the city it will do - consumption is about 8 liters, on the highway 6.5.
Denis, Omby. VAZ-2109, engine 1.3 carburetor, 1994 The car was purchased in 2000, in 2005 I took it for myself after the death of my father. Of course, it has undergone a lot of repairs, but overall the car is not bad - it has soul. Gasoline consumption in the city is 10 liters, on the highway 7 liters, but I like to press on the gas - if I drove more calmly, then the consumption would of course be lower.

Using fuel with a VAZ carburetor

The amount of substance used depends directly on how the modification of a number of UAZ cars works - on a carburetor or on an injector. First, let’s determine the fuel consumption of the VAZ 2109 carburetor, since it is believed that this type of system has the highest consumption:

2109 fuel costs in the city are 8-9 liters per 100 km;
gasoline costs on the highway - 6-7 liters per 100 km, at a speed of 90 km/h;
gasoline costs on the highway are 7-8 liters per 100 km, at a speed of 120 km/h.

Malfunction of valves or flaps in a VAZ

One of the main factors in increasing the indicator is a closed or not fully open air damper. You should always check whether it is in the correct position - the handle is facing the owner, and the part itself is in a vertical position. The same problem with an improperly closed solenoid valve or fuel nozzle leads to increased fuel costs for VAZ.

If the sealed mode of the needle valve is violated, excess portions of liquid enter the cylinders.

Problems with EPHH

If the XX system jets have a diameter that is too large, then too concentrated, supersaturated oil will enter the combustion chamber. Their contamination also causes increased consumption and requires immediate cleaning. An even more important factor is the breakdown of the forced idle economizer, which requires immediate repair.

VAZ-2109 1.5 carburetor

In 1988, production of the VAZ-21093 model began, equipped with a VAZ-21083 four-cylinder carburetor engine. This engine developed a power of 68 hp. and at 3400 rpm it achieved a torque of 104 Nm. This model was in production until 2006, until it was completely replaced by versions with injection engines.

For the VAZ-21093, the engine was paired only with a 5-speed gearbox, which made it possible to achieve significant fuel savings, especially when driving outside the city.

Fuel consumption rate VAZ-2109 1.5 carburetor per 100 km

Alexey, Barnaul. Before my “nine” with a 1.5 engine, I had the same one, but with a 1.3 liter engine. So, in terms of dynamics, the one and a half car is much more interesting, although the difference in power is only a couple of horses, but it turns much more fun. Well, in terms of consumption, the maximum I could get in the city was 10-11 liters in winter, but on the highway you can safely invest 6 liters.
Ivan, Irkutsk. I took my “nine” in 2009. Why the “nine” - for my budget they decided to take it better than a foreign car that was trashed. She served me for about six years - after that my dear was so tired that she simply refused to ride. Well, this is not surprising, because the car is from 1996, and more than 10 years is a long time for our automobile industry. Although, in principle, the machine is unpretentious, and the average consumption was 8 liters - for a 1.5 liter carburetor this is not so much.
Vladimir, Krasnoyarsk. The purchase of the VAZ-2109 was due to numerous advice in the style of “it’s better to buy a domestic car than an imported bucket of bolts for the same money.” I don’t know what the condition of the imported bucket is, but the belching of the domestic auto industry after a closer acquaintance (and I completely disassembled it) is terrible. The engine is mounted on one cushion, the whole body is rotten, the seats are different from each other - and that’s not all. The only plus is the consumption of 9 liters in the city.
Denis, Novosibirsk. I drive a 1997 Nine. One of the last ones to be produced with a carburetor. I bought the car in 2013, with a mileage of almost 200 thousand km. Yes, it needs to be repaired - but this is done simply and without hemorrhoids, and spare parts cost 10 rubles a bucket, unlike foreign cars. Consumption on the highway is 7 liters, in the city from 9 to 11 liters - depending on how you load it.
Arsen, Arzamas. My first car - I bought it for 90 thousand rubles in 2006. I drove it for 2 years, it started to rust and rot, half of the components fell off, even though the car was 1996. On the plus side, you can easily fill up with 92 gasoline, and consumption in the city is up to 10 liters.
Anton, St. Petersburg. VAZ-21093, -1996, complete stuffing (wheels, high panel, heated seats, electric windows). At the time of purchase - and this was 2005 - it was cool! Compared to the “six”, the car is much better - the suspension is softer, the gears are longer and you can safely go 120 km/h on the highway. I used A-92 gasoline and drove without problems with a consumption of about 10-11 liters in St. Petersburg.
Kirill, Barnaul. The first car, I repaired it a lot and for a long time - but this is probably how it should be, so after three years of ownership I began to quickly understand cars. In general, I’m happy with everything, the consumption is on average 8 liters per hundred square meters, and you can even pour A-80 without any problems if you’re really tight on money.
Alexander, Feodosia. I bought the car from a guy who had it in his garage for 5 years. Despite the fact that the owner treated the car well, this is still a domestic auto industry. The interior is uncomfortable, everything creaks and cracks, the electrics constantly short out, the body probably begins to rot right as the car leaves the workshop. And the consumption is 9-10 liters on this trough, which practically does not move... In general, I drove it for a year and sold it to hell.

How to adjust the carburetor on a VAZ 2109 for minimum fuel consumption

Hello everyone, my friends asked me here on the drive, what is the secret of low consumption and what are the settings of my Solex 83 carburetor.

layout, 73 Solex, thanks to Andrey Cherny.

I will tell you in order what and how I did and tried, I will describe my thoughts about the setup.

There are 3 variants of accelerator pump elephants

and this is precisely the first question about my carburetor.

bent, right?

Well, here are the types of elephants:

standard

The standard elephant was hitting who knows where, and when the damper was opened, the drops that remained on the wall began to drip. I set it up so that when it opens, the jets shoot out without touching each other.

like this

what did all this give me, the Solex has 2 modes, I call them up to 100 km per hour

, and
after 100 km per hour.
Well, so if I drove in the city cycle without pressing the pedal to the floor, the car drove rather sluggishly! and when the pedal was pressed sharply, a simply indescribable failure appeared. Why? I noticed that despite the fact that we drive quietly and we have 1 chamber working, the supply goes to 2 chambers and in the second chamber there is stagnation of fuel, I checked at home and the stagnation was about 6mm of fuel. It was decided to abandon this elephant.

consumption is approximately 11 liters per 100 km in the city + failures.

90s tuning, my father gave it to me.

tuning 90 what it looks like in the carb

The elephant out of 90 saved me from failure, the car simply cruised up to 100 km/h, but the car became stupid after 100 km/h. Consumption increased to 12-13 liters.

I tried to adjust the elephant, but one horseradish at the beginning it turned out to be drops, and then a stream.

VAZ-2109 1.5 injector

Since 1998, serial production of the VAZ-21093i model began, equipped with a VAZ-2111-80 injection four-cylinder engine with a power of 74 hp. and with a torque of 118 Nm. Compared to carburetor engines, injection engines not only developed higher power and torque, but also had better elasticity at low speeds and were more economical. These engines were also offered with a 5-speed manual transmission.

Reviews about fuel consumption of VAZ-2109 1.5 injector

Alexey, Tomsk. I wanted a car since I was 18 years old, but naturally there was simply no money for it. Then the car appeared, but another problem arose - I needed a working car, so that killing would not be a pity and would be inexpensive at the same time. I decided to take the injection “nine” 2002. Her condition was more or less - well, what condition can a ten-year-old VAZ have? In principle, it justified itself - spare parts are inexpensive, you don’t mind killing it, and gasoline consumption is 10 liters per 100 km in the city, an injector after all.
Alexander, Barnaul. VAZ-21093, 2002, 1.5 injector. Purchased with a mileage of 120 thousand km. Everything that could possibly creak in it creaked, and probably even more. There were a lot of mistakes, everything had to be done constantly, but for the money that I paid, I shouldn’t have expected anything else. But low fuel consumption - up to 8 in the city and up to 7 on the highway, as well as the ease of repair and low cost of spare parts compensate for many shortcomings.
Kirill, Abakan. I bought a “nine” in 2014. The car was produced in 2003, with a one and a half liter injection engine. I bought it when I was a student - what else did I need? The condition is normal, the owner himself admitted that one wing was broken, but it was made very well. At the same time, the luxury package is another plus. Well, efficiency - in winter the maximum reaches 11 liters, in summer about 9, on the highway it depends on the speed - from 6 to 7 liters.
Denis, Yekaterinburg. I learned to drive in my father’s service VAZ-2109, with a carburetor. In my second year at university, I managed to save some money and buy my own “nine”, but I bought it with an injector - it’s faster than with a carb, and its consumption is lower. In the city I drove consistently 50-70 km/h, consumption was up to 8.5 liters per 100 km, on the highway - no more than 120 km/h, consumption was accordingly about 7 liters.
Vasily, Ufa. In general, I have a Toyota Corona, but I drive a VAZ-2109 in my free time. I actually bought it by accident - at a gas station I saw a car with an advertisement on the rear window, talked to the owner and bought it. She was in good condition, the car was well maintained, the engine was tuned for maximum efficiency. Believe it or not, in the city 10 liters is enough for me for 130 km, i.e. consumption is around 6.5-7.0 liters per 100 km.
Grigory, Sergiev Posad. VAZ-21093i, 2001. When purchasing, the budget was 100 thousand rubles - not much, but true. Naturally, I chose only the domestic auto industry, I didn’t even look at foreign cars. In principle, “nine” is the cheapest and most practical option. Yes, you have to tinker with it, but the spare parts are inexpensive, repairs are also simple and can be done in the garage, and the fuel consumption of 8 liters in the city is quite low and no worse than that of many foreign cars.
Pavel, Moscow. "Nine" 1999. My faithful student car, in which I honestly drove throughout my studies at the university, transported a bunch of girls and my future wife. What else does a student need - consumption in Moscow is a maximum of 10 liters with traffic jams, comfort is not so great, but it is there, spare parts are cheap and you can easily repair it on your own with your dad and you.

Practical calculation of fuel consumption for vehicles of various carrying capacities

10 Standardization of fuel and electricity consumption for locomotives per trip
Each trucking company carries out standard calculations of fuel costs of a truck (calculated in l/100 km) independently. Just like with electronic calculators on the Internet, the disadvantage of generally accepted calculation methods is that they are based on average indicators. In the formula Qн = 0.01 x (Hsan x S + Hw x W) (1 + 0.01 x D), the base indicator is consumption without load in running order (Hsan), which is individual for each truck. Indicators of travel distance (S), work with cargo in fuel (Hw) and kilometers (W) change. Correction factors D (in percentage) are introduced, which take into account, on average, the increase in consumption rates for winter, large cities, the age of the truck, and the use of air conditioning. Actual fuel consumption may not coincide with the standards, which affects the choice of route. Thus, when transporting cargo from Odessa to Krivoy Rog, the logical choice of route is through Nikolaev, Bashtanka, Novy Bug, the length of which is 305 kilometers. For a Mercedes tractor with a factory consumption standard of 19.8 liters per 100 km, calculation on an electronic calculator will give a result of 60.39 liters. Calculation using the standard formula, with the standard for working with a load in fuel (Hw) of 5 liters adopted by the enterprise, more accurate. It takes into account a load of 20 tons and is equal to 0.01 x (19.8 liters x 305 + 5 liters x 305) = 75.64 liters. To this figure you need to add an additional factor of 15% for traveling 20 km through Nikolaev, which will increase consumption by 0.74 liters. In reality, you need to add 10% of fuel consumption to the standard fuel consumption on the 68-kilometer section of the broken road between Yuzhny and Nikolaev, where fuel consumption increases by 10% (1.68 l). The length of broken sections of the highway between Bashtanka and Krivoy Rog is 120 km. In these areas, the speed of the truck does not exceed 40 km/h, and fuel consumption increases by 15% (about 5 liters). Therefore, on a broken route, you need to add 7 liters of diesel fuel to the standard consumption. The total consumption will be 83.06 liters. A longer route through Nikolaev, bypassing Kherson, Berislav, Novaya Kakhovka, Ordzhonikidze, will be 445 km. With a fuel consumption of 111 liters, it will reduce travel time by 2 hours and protect the truck suspension from premature repairs. An additional diesel fuel consumption rate is being introduced for road trains. For road trains, standard consumption planning takes into account the weight of the trailer and the load capacity of the trailer. The load indicator (full or incomplete) is taken into account in the values of Hw and W. At the same time, calculations based on average standards do not take into account the speed of movement, transportation of cargo along overloaded highways (driving in the “gas-brake” mode), routes on bad roads (with regular braking ). Calculating diesel fuel consumption for routes in mountainous areas is especially difficult. Such sections of the route are passed in lower gears, for which diesel fuel consumption increases significantly.

Experienced drivers and private carriers with their own trucks do not use online calculators and correction factors. Fuel consumption is calculated using our own, empirically derived formulas related to the vehicle’s load, the total weight of the tilt or tipper road train, and the characteristics of the flat or mountain route. For each driving mode and individual sections of the route, the driver draws up a separate sign.

By correctly measuring and calculating fuel consumption, the driver can plan the costs of the car’s route mileage and be confident in the successful completion of profitable cargo transportation.

VAZ-2109 1.6 injector

In 2001, the VAZ-210934-20 model appeared. As a power unit, it uses an injection four-cylinder 8-valve VAZ-11183-20 engine with a volume of 1596 cm3. It produces 81 hp. and a torque of 120 Nm and is combined with a 5-speed manual transmission.

Real reviews about fuel consumption of VAZ-2109 1.6 injector per 100 km

Evgeniy, Ekaterinburg. I’ll say right away that I bought the car to drive. There is nothing native left in her anymore. The engine is 1.6 liters and that friend rebuilt and rebuilt it for me, it now produces more than 100 horses. Consumption, of course, has also increased - in the city it’s about 14 liters, if you drive calmly it’s about 10 liters. But I like it and do everything at the traffic light.
Ilya, Samara. After I got my license in 2005, I had exclusively domestic cars for almost 8 years. The latest from our automobile industry is VAZ-210934-20, with a 1.6 liter injection engine. The car was produced in 2001, it has covered 150 thousand in 10 years. After the purchase, the engine, suspension and everything else were overhauled - the rest did not cause problems. I’ll tell you, the car is reliable and unpretentious, if you look after it, and it’s also economical - in the city it’s never been more than 9 liters, on the highway it’s about 5 liters in general.
Denis, Anzhero-Sudzhensk. I bought a car from my father - he still saved up the money to switch to a foreign car, but I got my own car. Its main feature is the engine, 1600 cubes. Consumption in the city is about 10 liters, well, for any car with such an engine it is almost identical. I drove it for a year and a half and decided that it was expensive to refuel with gasoline - I installed an LPG system. Consumption has increased, but this is also because I stopped saving - now in the city I have a stable 12-13 liters, but given the price of gas, this doesn’t bother me at all.
Kirill, Barnaul. I don’t care about those who criticize the domestic auto industry. Yes, it may be inferior in quality and reliability to foreign cars, but it is also much cheaper to buy and to operate. And if your arms are straight, then everything will be fine. I bought it with a mileage of 150 thousand - I only replaced the chassis, pump and cooling fan. The timing belt was changed at 175,000 km!!! The 1.6 liter engine performs very well, the brain did not float at all. And also economical - in mixed mode it never produced more than 7.5 liters.
Timofey, Sergiev Posad. "Nine" with a 1.6 liter injector, 2003. Before it there was a “five” - when I changed, it seemed like I was driving a foreign car. Consumption up to 12 in the city and 7 on the highway, I adjusted everything to suit myself - in general, it didn’t bother me at all for 3 years (although I still did minor repairs). Now I’m thinking of selling and buying a Skoda.
Vasily, Krasnoozerskoe. VAZ is a VAZ. You always know what to expect from him, you know that even with serious repairs you will be able to support him financially. And it carries its rear just like a foreign car. The downside is the constant noise in the cabin, everything creaks and rattles. Consumption on the highway is about 7.5 liters, in the city 10 liters.
