VAZ 2114 in detail about fuel consumption

The VAZ car has been mass-produced since 2001. In the new model 2114, the creators installed a modernized instrument panel and changed the lining on the radiator. What is the fuel consumption of VAZ 2114? This question causes a heated discussion among car owners. So, some indicate a low consumption of gasoline, while others - about the "voracity" of the car. Fuel consumption 2114 VAZ depends on many external and internal factors, knowing which, you can control consumption.

Technical specifications

To determine the consumption rate of VAZ 2114 gasoline on the highway and in the city, it is necessary, first, to familiarize yourself with the technical equipment of the car. Automotive since 2014 has completely changed the concept of equipment. TSo, she showed the world a car with an 8-speed engine, a volume of 1,5 liters, and with 16 steps and a volume of 1,6 liters. A common characteristic of the models is the presence of a manual gearbox with 5 steps. Fuel consumption in the 8-valve VAZ 2114, according to the test drives, is quite large.

Engine	Consumption (track)	Consumption (city)	Consumption (mixed cycle)
1.6 5-mech	Xnumx l / xnumx km	Xnumx l / xnumx km	Xnumx l / xnumx km

To understand the problem of high gluttony, you should know what the fuel consumption rate is for Lada 2114 and the reasons for its increase. The average fuel consumption of a VAZ 2114 per 100 km can always be found in the technical data sheet of the car. According to the documentation, the gasoline consumption of the car is from 8 to 10 liters per 100 km.. However, numerous reviews show that for some owners this figure increases by 2-4 times. So, what influences high consumption?

Possible reasons for the increase in consumption

The actual fuel consumption of a VAZ 2114 car may increase due to the following factors:

• gasoline consumption increases if the filter responsible for air supply is clogged;
• another reason is unstable tire pressure;
• if the filter is clogged;
• gasoline consumption on the injection VAZ 2114 increases in the presence of breakdowns, for example, an oxygen supply sensor or DSA;
• low-quality fuel;
• the reasons for the increase in consumption may be a non-standard radius or a low level of compression. 

The simplest reasons

Increased fuel consumption appears due to filter contamination. This is the simplest reason that it is not difficult to deal with on your own.

So, if you notice that your car began to "eat" much more than usual, then immediately check the filter for clogging.

This factor is able to increase the cost of the car by 3 liters. To get rid of the problem, you need to replace the filter.

The second factor in the increase in fuel consumption is considered to be a violation of the stability of the pressure in the VAZ tires. This problem creates a lot of trouble, especially if the car has non-standard wheel radii. After all, if you have large tires, then turning them yourself is almost impossible. To solve the problem of gasoline consumption and pressure, it is better to contact a service station.

Effect of valves on fuel consumption

You can analyze the functionality of the valves using a special lambda umbrella device. Malfunctions of the oxygen supply system can be seen on the on-board computer panel, or after diagnostics by specialists. Valves stop working for the following reasons:

• refueling a car with low-quality gasoline;
• unexpected valve clamping;
• rings do not allow the optimal amount of oil to pass to the valve;
• advance angle set incorrectly.

Influence of sensors on flow

Fuel consumption for Lada 14 in the city or outside it may increase if the speed sensor fails. So, during the run, he is responsible for transmitting information about the speed to the control unit. Fuel consumption may increase due to incorrect data, causing the control system to release more gasoline. The method for diagnosing the problem is the same as the previous methods. The sensor device is located on the box.

The first signals of a malfunction of the speed sensor may be such reasons:

• if at idle you notice that the engine stalls;
• evidence of a sensor malfunction - there are malfunctions or failure of the speedometer;
• "floating" idle turns;
• increased fuel consumption;
• engine thrust has dropped.

The effect of a gasoline pump on consumption

Gasoline consumption can increase significantly in the event of a malfunction in the fuel pump. This VAZ model is equipped with an electric type of pump. If the parts wear out, then the pressure of transporting gasoline drops. This problem results in a significant increase in fuel consumption. Among the signs of a malfunction are:

• troit engine;
• drop in power of a VAZ car;
• increased consumption of gasoline;
• often the engine stalls.

The role of the nozzle in the consumption of VAZ

For the fuel consumption of a VAZ car, the condition of the injectors is of no small importance. During operation, they become contaminated with dust and dirt. You can solve the problem in various ways, for example, clean them yourself or use the service of a specialist. Indicators of the need for cleaning:

• an increase in gasoline consumption was noticed;
• the exhaust pipe became more toxic and the smoke turned black;
• the optimal operation of the motor is disrupted;
• when accelerating at about 100 km per hour, dips are observed.

Ways to reduce fuel costs

The most important rule is to timely diagnose a car, because fuel consumption largely depends on malfunctions inside the car. In order to keep the consumption of gasoline normal, you should follow these recommendations:

• carry out periodic replacement of the air supply filter;
• periodically diagnose the functioning of the spark plugs;
• help control the cost of gasoline - keeping the engine compartment of the VAZ clean;
• give preference to trusted gas stations and high-quality gasoline;
• control the operation of the brake system.
