so something is wrong with you!

The stock car should consume 0.7-0.9 l/hour at idle 880 rpm

Continuing the line of the “nine”, beloved by domestic car enthusiasts, the “Samara 2” or VAZ 2114 model was released. A new dashboard was installed in the car, the exterior was modernized, and the interior was improved. The car was released in 2001 and immediately received positive feedback from its owners. It turned out to be so popular that production continued until 2013. Among the advantages of the car are:

1. Attractive appearance.
2. Reliable, economical and dynamic engines.
3. Economical average fuel consumption on all modifications of the VAZ 2114.
4. Maintainability.
5. Optimized chassis.
6. Reasonable price for any of the configurations.

The cars are equipped with a range of engines with volumes of 1.5 and 1.6 liters, the second unit is offered in versions with 8 and 16 valves.

• 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.

The main culprits of overspending

If fuel consumption increases sharply, the first thing to do is check the filter. Debris in the fuel or air filter can significantly increase gasoline consumption. What can we say if even low tire pressure leads to the same result. But the main reason for the “gluttony” is the sensor. He is not the only one in the VAZ 2114 device, so let’s dwell on this point in more detail. Increased consumption may be caused by a malfunction of the following devices.

1. Lambda probe - installed in the exhaust system, it regulates the working mixture. Most often, the device fails due to low quality gasoline, incorrect mixture, pinched valves, broken oil rings, and an incorrectly set advance angle.
2. Speed ​​sensor - if traction has dropped, idle speed is floating, the speedometer is unstable, and fuel consumption is high, then it is most likely to blame. You can find it on the top cover of the gearbox.
3. Phase sensor – we discussed all the nuances of this device in the previous article.
4. Electric fuel pump - the symptoms are still the same. You can accurately determine whether there is a problem with it using a pressure gauge.
5. Injectors - failures during acceleration, low engine dynamics symbolize their clogging.

In addition, if consumption has increased, the following nuances may also be to blame:

• Low engine compression;
• Broken ignition;
• High voltage cable rupture;
• Faulty spark plugs;
• Unregulated gas distribution system.

Most self-taught mechanics cannot understand why, after replacing a sensor, the on-board computer continues to give an error. I have already talked about how to reset its readings many times; to do this, simply disconnect the battery terminals for a few minutes.

This is roughly what the main points that can change the standard fuel consumption look like. Watch what kind of gasoline you fill up, and also be prepared for increased consumption in winter. And that’s all for me, follow the development of the blog and leave reviews! Not a nail or a rod!

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.

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.

Reviews from VAZ Lada 2115 owners. Car engine

The increase in consumption is influenced by driving style; to reduce it, you do not need to accelerate and brake too actively, keep the engine in the range of 2000-3000 rpm. Malfunctions of the air flow sensor or absolute pressure sensor, lambda probe, and camshaft position sensor have a noticeable effect on gasoline consumption.

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.

Specifications

This is an improved model of the well-known VAZ 21099. The sedan that replaced it has become more popular than its predecessor. It features a number of positive innovations, which include a more modern assembly, economy, and the necessary comfort for the driver.

In Samara, the front optics have been modernized, the design has become streamlined and modern, and the stylish updated trunk lid attracts the attention of many consumers. The modified sedan can be equipped with electric windows, fog lights or heated seats. The on-board computer has become a classic feature for this car.

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.

The truth is in the numbers

So, the amount of gasoline consumed over a period of 100 km is an indicator of fuel consumption by your car, which is directly influenced by the technical characteristics of the car’s power unit. The most popular injector on the VAZ 2114 is the 1.5 (78 hp) and 1.6 (81 hp) liter engine. Accordingly, the consumption of these models differs slightly; the difference is clearly visible in the photo. Also, the design of such a power unit may have 16 or 8 valves, but this does not change anything in our question. Like other models of four-wheeled vehicles, the “fourteenth” demonstrates minimal consumption on the highway. If you control the speed within 70-90 km/h, you can achieve the level of small cars - 5 liters. As for driving around the city, it all depends on your driving style. An experienced conqueror of the streets of a metropolis will not spend more than 10 liters over the same 100 kilometers, but in another case, the “appetite” can grow to “Volgov” 13-14 liters. The photo above shows the declared average, maximum and minimum consumption levels of both engine types. Oddly enough, the actual consumption is not much different from the factory one.

Many drivers are often interested in how much power a car consumes at idle speed? As for measuring spent gasoline while standing, the measurement procedure is completely different. Here we cannot use a kilometer segment, but only a time one. Therefore, the usual 100 km replaces one hour of engine operation. "VAZ 2114" for the allotted period of time consumes no more than 1-1.3 liters of gasoline. If this number is higher, pay attention to the idle speed sensor.

How much does a new sensor cost... High voltage wires

1. Regularly replace the air and fuel filter. In this case, preference should be given to factory elements.
2. Monitor the condition of the spark plugs and replace them according to the recommendations.
3. Periodically measure the tire pressure level and monitor the condition of the brake system parts.
4. Refuel your car only at time-tested gas stations.
5. Maintain cleanliness of components and assemblies of the engine compartment.
