• low pressure in the fuel system due to a faulty fuel pump;
• filter contamination - fuel or air;
• problems with sensors - speed, camshaft position, oxygen supply;
• dirt in the injectors.

Ways to reduce fuel consumption of a VAZ 2114 with an injector • It is a long-known fact that the larger the radius of the wheel, the more effort must be made to turn it.

Varieties

Nowadays, having a car in your arsenal is considered not a luxury, but an additional convenience. After all, many car owners can get to work by car, and it’s convenient, simple and easy to bring the harvest from the dacha in their own car. Among the numerous models of domestic cars, the VAZ-2110 is in greatest demand among buyers. When purchasing this model, regardless of the type of engine, which can be either 8 valves or 16 valves, everyone, without exception, is interested in the fuel consumption of the VAZ-2110 car and, of course, the technical characteristics of the iron four-wheeled friend. We will try to analyze these questions further in the article.

Sequence of diagnostic work

Before intending to bring consumption to factory values, it is advisable to narrow the range of reasons, starting with electronic, fuel systems, sensors, filters.

The sequence of inspection stages for the VAZ-2110 includes:

How much does a new sensor cost?

Of course, car parts are not cheap, but if necessary, they must be purchased in order for the vehicle to work properly. The sensor should be purchased only in specialized stores where there is a guarantee, and where you can actually get competent advice. This spare part costs around 350 rubles. As a rule, such options are very reliable and durable. It makes no sense to buy cheaper ones, since their characteristics are in no way inferior to those that cost 350. It’s not worth buying cheaper ones, because these are mostly Chinese parts that are short-lived and of poor quality. If you find it difficult to choose, then ask the seller which sensor is better to choose. Basically they are all similar, the only difference is the price. Please note that this part can also be purchased online. The main thing is not to be cheap, but also not to spend all your money on one spare part.

As we can see, any part of the machine becomes unusable over time, so it needs to be replaced. As for the idle speed sensor, this device also needs to be replaced from time to time for the accuracy of the indicators. Quite often, due to a faulty sensor, a car begins to have problems with the engine, the speed deteriorates, etc. With such problems, it is quite dangerous to drive a car, since there is no guarantee that the engine will work without “whims,” and on the road this is very dangerous . You shouldn’t risk your most valuable assets; it’s better to send the car in for repairs or fix it yourself. A car, like any other device, must be used carefully and repaired as needed, then it will serve for a long time and reliably.

• They are made of quality materials;
• They can overcome any obstacles;
• They cope with any trails and conditions.

Injectors are the most important part

Lack of control of the engine condition leads to a decrease in efficiency and, as a result, the engine “troubles” due to contamination of the injectors. They are located in the ramp, which, in essence, is the “vital organ” of the motor. There is weak atomization of gasoline, incorrect and unstable formation of the mixture. The way to eliminate the problem is to clean the injectors. The conventional expression “cleaning the injector” is a wrong term, because... there is no such device. There are only parts of the injection system, such as a pump, ramp, injectors, etc. To protect injectors, special means are offered on the car market, but:

• they do not provide 100% protection;
• it is difficult to find high-quality “chemistry”;
• it can cause damage to the car.

Note. The reason is loose dirt and other waste products that successfully clog the holes through which the fuel-air mixture is supplied. So its supply is partially or completely blocked.

Next, we will find out which sensors affect fuel consumption.

For example, a knock sensor only prevents detonation knock when refueling a car with low-quality gasoline and commands the control unit to set a later ignition. If it’s summer and you drive on normal roads, but at the same time you notice an abnormal appetite in the fuel-injected 8-valve VAZ 2114, then it’s time to conduct a full diagnosis of the car’s condition.

What is the real gasoline consumption of VA3 2114? Symptoms of a problem

• malfunction of the oxygen supply sensor;
• low level compression;
• problems with the air flow sensor;
• late ignition, clogged catalyst.

In such a distribution system, injectors are installed on the intake tract of each individual cylinder, and when equipped with a sequential type of unit, fuel is supplied directly to the combustion chamber. Using the example of a 2111 injection engine with a fuel injection system and an ECM control system to Euro-2 standards with one oxygen sensor for VAZ 21083, 21093, 21099 cars.

How to avoid high fuel consumption

To reduce fuel consumption, it is necessary to remove additional elements that increase aerodynamic drag when driving. For example, a plastic trim on the leading edge of the hood or deflectors around the side windows lead to additional fuel costs (within 0.2-0.3 liters per 100 km). A negative impact is caused by low air pressure in the tires or incorrect operation of the brake mechanisms, when the pads touch the surfaces of the drums or discs when the pedal is released.

CAUSES

An error in the operation of the oxygen sensor can be detected at a service station by going through the diagnostic procedure, or the on-board computer will give you a hint. Considering that today the cost of gasoline is quite high, it is easy to guess that increased consumption can make a noticeable hole in the family budget of an ordinary person, when every trip becomes literally golden.

Functions of mass air flow sensor

There is no need to rush to replace the device, since it is likely that it just needs to be repaired. If you are not good at this, then it is better not to risk repairing the sensor yourself. In order to organize its work, you must have certain knowledge and skills. If you have never done this, then seek help from a specialist, as incorrect repairs can lead to serious problems with the operation of the engine and other components of the car. If you understand the insides of your vehicle, then proceed as follows:

8kl engine 2111 1.5 mt 77 hp

This engine was the first to be equipped with the VAZ 2114, or as it was called - “Samara-2”. Thanks to the power of 77 horsepower, the car accelerated to 100 km/h in 13 seconds, while the maximum speed reached 165 kilometers per hour. The manufacturer claims that in urban driving mode the engine consumes 8.

According to reviews from real owners, the gasoline consumption per 100 km of the VAZ during everyday use is slightly different. Usually the figure differs from the passport number in a larger direction:

• in the city - 7.5-9.5 liters;
• on the highway - 4.5-6.2 liters;
• mixed cycle - 7.3 l.

Even with aggressive driving, the car does not overcome the psychological barrier of 10 liters, which makes it an excellent choice for people who do not want to incur huge expenses on gasoline. Differences in fuel consumption figures depend on driving style and the condition of the car, in particular, the serviceability of all units and components.

Bottom line

A car with an injector and built-in computer technology can easily be tuned, which gives it a more modern look, aesthetic beauty, and more comfortable operation. The above indicators of gasoline costs according to real data and according to the technical data sheet do not have significant differences

. It all depends on the care of the car, parking location, and weather conditions.

Despite the fact that the production of this car has already ended, you can see many happy VAZ owners on the roads, which indicates its reliability, high wear resistance, economy in maintenance and fuel consumption. The plant in Togliatti, where the car was produced, has been famous for many years for the high quality of the vehicles produced, which are optimally suited to the conditions of use in our region.
