VAZ 2114 tank volume: finding out the real numbers

Specifications 2114

Before we look at the main question - how much volume the VAZ 2114 tank holds, let’s look at the main technical characteristics of this car.
Its engine parameters are as follows:

• working volume - 1499 cm3;
• total power - 77 hp;
• maximum rotation speed - 5200 min-1;
• maximum torque - 116 N/m.

In turn, the main operating parameters of the VAZ 2114 car look like:

• acceleration time from 0 to 100 km/h - 14 s;
• maximum possible speed - 157 km/h;
• fuel consumption in urban conditions (per 100 km) - 9.9 l;
• fuel consumption on a suburban highway (per 100 km) - 6.2 l;
• fuel consumption when traveling in mixed conditions (per 100 km) - 7.5 liters.

Now consider the main weight and dimensions of the car:

• total length - 4122 mm;
• full width - 1650 mm;
• height - 1422 mm;
• ground clearance - 165 mm;
• wheelbase size - 2460 mm;
• front track - 1400 mm;
• rear track - 1370 mm;
• weight (curb) - 985 kg;
• weight (total) - 1410 kg;
• fuel tank volume (full) - 43 l.

As you can see from the table above, the gas tank on the VAZ 2114 holds exactly 43 liters. Is this really so? Let’s look at it below.

Actual tank volume on the 14th model

As mentioned, the manufacturer claims that the volume of the 2114 tank is 43 liters (in some cases you can find a figure of 42.5 liters). And this figure is indeed very close to reality.

At the same time, it is worth considering a number of facts that can significantly affect capacity:

1. Errors in the manufacture of the tank.
2. Time of year and temperature.
3. Fuel system volume.

The first of these factors is usually insignificant. But, as practice shows, sometimes the difference in the volumes of two identical tanks can reach (as a result of low production accuracy) 2 liters. Thus, on some machines the total volume can reach 45 liters (which is extremely rare).

This should also include the difference in weather conditions. In cold weather, the fuel contracts, and in warm weather, it expands. This factor also affects how many liters the tank on a VAZ 2114 can hold (if we take into account the full volume of gasoline that can fit in hot summers and winter frosts, the difference can reach 1.5 liters).

Well, finally, you should remember that the fuel system itself also holds a certain amount of fuel. On average, when the tank is completely empty, up to 2 liters of gasoline can remain in it. As a result of this number of features, the amount of fuel contained in the tank may differ from that declared by the manufacturer, either more or less.

If at a gas station you managed to fill 50 liters of fuel into an almost empty tank, then this can become a good reason to complain about the accuracy of the filling device and the operation of the station itself. Such a large difference in volumes cannot be attributed to any of the above errors.

It is also worth noting that if the vehicle is operated incorrectly and refueled with low-quality fuel, sediment can accumulate at the bottom of the tank, which over time can (albeit insignificantly) reduce its volume. In order to avoid such a situation, the tank should be inspected every few years.

If the warning light on the panel lights up, it means you can fill the tank with up to 35 liters of fuel without fear of it overflowing.

Consumption and travel distance

If we take into account the volume of the VAZ 2114 tank and the data on gasoline consumption (given in the table above), we can draw the following conclusions about the possible travel range.

When driving at a constant speed of 90 km/h, the maximum range can be almost 700 km without additional refueling.

When traveling in the so-called “mixed” city/highway mode, consumption will increase, which means the range will decrease (up to 640 km).

And when traveling only in city mode (taking into account standing in traffic jams and a large proportion of driving in low gears), fuel consumption will be maximum - almost 10 l/100 km. It is also worth considering that these figures are for new cars. For used cars they will be slightly higher.

Signs of breakdown

There are several situations in which the pump or its components can be at fault. This will definitely have to be checked. Otherwise, you can spend a lot of money buying and installing a new fuel pump, but in the end it turns out that the problem is completely different.

1. The engine will not start. This is not a clear sign of problems with the pump, but still. Therefore, first check the condition of the spark plugs, the presence of a spark, and the absence of traces of oil on them. Also check the electronic control unit.
2. Pressure inside the fuel system. If the pump is operating normally, it will create a pressure of 3.2 bar. Depending on the type of engine in your VAZ 2114, the characteristics may differ slightly: For a 1.5-liter engine, the optimal values ​​are 285-325 kPa;
3. For a 1.6-liter engine, these characteristics in optimal operating mode will range from 375 to 390 kPa.

There is no signal that is not sent to the pump. This happens when you turn the ignition key. During normal operation, the pump begins to vibrate slightly when turning the key. If this does not happen, be sure to check the wiring. Troubles the power unit. This is also not an ideal sign of a fuel pump failure. But you still have to check. It is likely that the culprit in this situation will be the pump. The engine jerks. Moreover, this happens at low speeds or even at start. There are two possible reasons for the situation - a breakdown of the pump itself or a problem with the fuel pump grid, which will have to be replaced.

New and old coarse filter Many people purchase the entire fuel module assembly at once, which includes a filter, sensor, float, intake chamber and the pump itself. Such a purchase will cost approximately 3,000 rubles. It is much more profitable and practical to buy a separate pump, which costs up to 1000 rubles. This is due to the fact that when the pump fails, the remaining elements almost always remain intact and are fully suitable for further use.

Fuel tank design

The main function of a fuel tank is to store a certain amount of fuel. At the same time, everything must be organized so that the likelihood of a fire hazard is minimized.

On VAZ cars the fuel tank is located under the rear seats. Due to this placement, in the event of serious accidents and car overturns, the tank in most cases remains undamaged. VAZ fuel tanks are made of leaded steel sheets. Thanks to a thin layer of lead that protects against corrosion, the service life of the tank is significantly increased. The outside of the fuel tank is covered with dark enamel.

The fuel storage volume of the VAZ 2108 and other similar models is 43 liters. This takes into account the reserve, but it is not recommended to fill the tank to the brim. You should always leave a free volume of about four liters. It is especially important to do this in the summer, since the fuel expands as the temperature rises. If the tank is filled to the brim, then after swelling it may simply burst. The volume of the VAZ gas tank is designed in such a way that the autonomous mileage is enough for 500 kilometers, and this is considered a normal road segment in modern conditions.

The tank is securely fixed to the car body using flexible and durable plate-type clamps. Rubber gaskets must be placed under the clamps to ensure a tighter connection.

The tank mounting plates are very flexible and durable

Gasoline is poured through the neck on the right (in the direction of travel) rear side of the body. It is closed with a screw cap.

Main elements of the fuel tank

The neck is connected to the tank cavity through the filler hose. The other two tubes are integrated with a seven-liter separator installed outside the tank and designed to capture gasoline vapors. As a result of wear, the separator may split along the seam and gasoline will begin to leak out. It can be replaced without dismantling the tank. Moreover, you can temporarily cover the separator seam with a gasoline-resistant sealant.

The separator tank holds seven liters of fuel

In order not to remove the separator (it is necessary to dismantle the bumper and filler pipe), experienced car owners simply disconnect the hoses of the element and cut it out with metal scissors. In place of the separator, a fine fuel injection filter is installed, which performs similar functions.

Instead of a separator, you can install a fine fuel filter

Some separators are equipped with a double-acting valve to minimize fuel leakage. The valve admits and releases gasoline vapor. Once in the tank, the vapors condense and thereby reduce fuel consumption.

The fuel system of the VAZ 2112 car is quite simple

The tank of VAZ cars produced after 2000 is equipped with a fuel level sensor (FLS), which regulates the amount of gasoline in the tank and sends data to the electronic control unit (ECU). The sensor is fixed through a rubber gasket and can be easily removed through the rear seat.

The fuel level sensor is installed on all VAZ models produced after 2000

Why is a subwoofer needed and what types of this speaker are known?

Whatever the subwoofer, its role is predetermined - it only complements the existing speaker system and is not needed for full bass reproduction. This means that without a subwoofer, some bass will play normally. For example, this applies to low frequencies of 80-200 Hz.

Installing a subwoofer in a VAZ 2114

There are two main types of subs: in a box and without it.

Let's start with case models:

• They are delivered in a box, the size (volume) of which may vary;
• In turn, such subwoofers can be either active or passive (see Which subwoofer is better: consider active or passive). The former initially have a built-in power amplifier along with a frequency divider or crossover, as it is also called. Subwoofer passive has neither an amplifier nor a crossover, but costs several times less than the first;
• The second type of subs comes without a housing. Such models crash into the rear parcel shelf or seat of the car.

Subwoofer in the wing of a VAZ 2114

For hatchbacks, such as the VAZ 2114, it is recommended to install an active subwoofer (see The best active subwoofers for cars and their review), since the shelf above the trunk will not prevent bass from penetrating into the body. The same applies to station wagons, but for sedans an open speaker embedded in the rear seat is more suitable.

Major damage to the gas tank

When using a fuel tank for a long time, situations arise that require repair. First of all this:

• holes and cracks resulting from mechanical stress and corrosion;
• clogging of pipes and hoses directly connected to the tank;
• damage to the connecting seam at the junction of the tank halves.

Small cracks are usually sealed. This is a rather labor-intensive procedure, but the functionality of the tank can be completely restored. In case of major damage or holes, the tank is replaced with a new one. Dirt gets into the hoses along with low-quality fuel. In this case, the mesh through which gasoline enters the tank may become clogged. Therefore, it must be periodically washed and changed. In addition, you should only refuel at proven gas stations and do not abuse additives to reduce fuel consumption. The weakest point of the tank is the seam, which is constantly subjected to severe stress. This can be avoided if the tank is made in one piece. The fuel tank can also fail due to deformation of the neck, formation of dents after an accident, separation of partitions inside the tank, etc.
