Automobiles VAZ-2114 are popular in Russia. These are inexpensive and laconic machines that are available to the middle class. However, practice shows that many car owners are concerned about fuel consumption per 100 km: VAZ-2114 often consumes fuel in a volume exceeding the declared consumption.
It is worth considering that there is a passport andthe actual fuel consumption of VAZ Lada 2114. Quite often these two parameters do not match. If you believe the manufacturer, this car with a power plant with a volume of 1.5 liters in a mixed cycle should consume 6.8 liters of gasoline per 100 kilometers of run. Thus the expense on a line makes 5.2 l, in a city - 8.9 l.
Fuel consumption per 100 km (VAZ-2114 with a motorvolume of 1.6 liters) will be 7.2 / 5.4 / 9.8 liters in mixed mode, along the highway and around the city, respectively. As you can see, the figures are very attractive, which means that the car is economical.
However, if you believe the reviews, then at the VAZ-2114the fuel consumption per 100 km is much higher than the one declared by the manufacturer. With an engine capacity of 1.5 liters, the maximum consumption of gasoline when driving in urban conditions is 12 liters. With a motor volume of 1.6 liters, the consumption is 13.5 liters per 100 kilometers. As for traffic on the highway, here the parameter is practically the same as the declared parameter - 5.5-6 liters per 100 kilometers of run. In mixed mode, the car "eats" about 7.5-8 liters per hundred.
Some owners have a much higher fuel consumption, but often there are some malfunctions with the engine or some element of the fuel system.
The list of malfunctions that cause increased consumption of gasoline by the engine can be great. Here are the main ones:
Sometimes solve the problem of huge fuel consumptionVAZ-2114 can be independently. First of all, you need to check the degree of contamination of the fuel filter and check it for debris. If there is debris inside or suspected contamination, then it is better to replace it. This element is inexpensive, and its price on average is 300 rubles. You can replace it yourself - it's easy and does not require specialist intervention.
The second filter is air. Through it passes air, which is then mixed with gasoline and fed into the combustion chamber. And if he is dirty, he will not be able to pass enough air. As a result, the air-fuel mixture will not be enriched with oxygen, and a poor fuel mixture will logically lead to an increased consumption of gasoline. Often car owners manage to reduce gasoline consumption by about 3 liters per 100 kilometers by simply replacing the air filter. It is easy to change it - it is in a large black box under the hood.
One of the first and important sensors, workwhich can affect the increased consumption of gasoline, is a lambda probe. It is located on the exhaust pipe, and its main task is to assess the state of the exhaust gases. In terms of content in the exhaust of oxygen, the system regulates the volume of the working mixture. Accordingly, in the event of a sensor failure, the system will not be able to fine-tune the working mixture that needs to be supplied to the combustion chambers. From this, consumption can increase.
However, in the event of a sensor failure, the system of thiswarns the driver with a "Check" light on the dashboard. You can also see the error using an on-board computer. Often this sensor breaks down due to poor quality of gasoline, oil entering the combustion chamber, clamping the valve.
Also cause a large fuel consumption per 100 km(VAZ-2114) can be a speed sensor. Its main task is to transmit information about the speed of the car to the control unit. The latter monitors the operation of the motor, adjusting the throttle. The problem with this sensor will be displayed on the on-board computer, or an error reading device. It is almost impossible to replace it independently without specialized knowledge. Characteristic symptoms of a speed sensor failure:
Crankshaft Position and Distribution Sensoralso called a phase sensor. It determines the cycle of the engine and, depending on this, generates a signal. Such a sensor is not installed on all VAZ vehicles. In the event of a malfunction, the "Chek" will light up on the instrument panel, and in addition to the increased gasoline consumption, there will be a drop in engine power, detonation of fuel in the combustion chamber, and stopping the engine on neutral transmission.
Injectors through which the injection is carried outfuel in the combustion chamber, too, can cause a large flow. They become clogged and need to be cleaned. There are different options for cleaning: you can turn to the service station, and you can buy a special additive to gasoline, which cleans the entire fuel system of the car, including the injectors.
Usually normal gasoline consumption during operationThe engine in idle mode is 0.8-1 liter per hour. If these indicators are not exceeded, then it means that everything is normal with the system. If the consumption is increased, then it is worth checking the same sensors. However, special attention should be paid to the idle speed sensor, which automatically regulates idling speed. It is located on the throttle knot and fixed with a pair of cogs. The device does not have an electronic system, so its failure will not be displayed on the dashboard in the form of a "Check". To judge its malfunction is possible only by certain criteria:
This sensor is designed to adjustdosage of the mixture. It determines and reports to the computer the throttle position. Given that the device is part of the throttle assembly and connected to the electronic system, a "Check" will light up on the instrument panel in the event of a malfunction of this sensor. The symptoms of the fault are exactly the same as in the case of an idle sensor.
Actions are banal: you need to use high-quality gasoline, replace the consumables in time (fuel and air filters, oil, oil filter), monitor the condition of the sensors, and in case of a suspicion of a malfunction, you need to contact specialists.
Now you know what fuel consumption is 100 km from VAZ2114, and what elements can affect the increased consumption of gasoline.
