At operation of the car, often drivers face a problem of increase in fuel consumption. The reasons of a big consumption of gasoline there is a set. But, nevertheless, more exact answer can be received only after special diagnostics.
Main reasons of increase in fuel consumption
Very big consumption of gasoline can be connected with various malfunctions in the electronic system operating the car motor. In such situation it is necessary to address to the service center which specialists are capable to find and remove the cause of this problem quickly in due time.
Pressure in a fuel system - raised or lowered can also influence a big consumption of gasoline. In the first and rather rare option just it is necessary to install the special regulator. And here the second case can take place because of wear of the fuel pump, damage by its abrasive parts which contain in fuel of poor quality, and contamination of the fine filter. For normalization of pressure in a fuel system, so, and decrease in a consumption of gasoline, it is necessary to carry out works on elimination of these problems and malfunctions.
One more reason of very big consumption of gasoline - contamination of injectors. It leads to misoperation of the engine and as result - to gasoline combustion empty in the catalyst of the car and a final collector. At contamination of the air filter the loading pays off incorrectly, and fuel consumption considerably increases. To avoid emergence of this problem, it is regularly important to make washing of injectors and in due time to replace air filters.
One more answer to a question why there was a big consumption of gasoline, lies on a surface. The working conditioner, especially, if a large number of time is spent in traffic jams, takes away an essential share of the spent energy of the motor for operation of the compressor.
If the car is not equipped with the mode of blocking of the hydraulic torque converter, it practically always influences very big consumption of gasoline. Therefore it is very important to avoid use of the transmission in emergency operation and in due time to carry out its diagnostics.
In the winter the consumption of gasoline will be more if not to reach the optimum temperature of the engine. Also fuel consumption is influenced by style of driving: sharp braking or, on the contrary, driving at a high speed. Quiet and measured driving will help to save on fuel.
How to measure fuel consumption?
To define a car gasoline consumption, it is necessary to fill in a full tank of fuel. Can make it to top of a mouth and it will not turn out as some fuel tanks are equipped with the non-return valve which is doing not pass gasoline outside through a jellied opening. But, nevertheless, it is necessary to try to fill a tank with the maximum accuracy.
Now, having dropped indications of the odometer on zero, it is possible to go. And it is important to do it on the direct route with a speed of 90 kilometers per hour, without braking and without accelerating. What the bigger distance will be overcome by, the end result will be that more precisely.
After the trip it is necessary to go to a touch the gas station and from the same gun to fill in gasoline in a tank to top. It will give the chance to define amount of the spent gasoline, and the odometer will show the passable way in kilometers. Now the number of the spent liters needs to be divided into kilometers and to increase by hundred. The received number - a gasoline consumption on 100 kilometers.
At measurement it is very important to consider quality of the filled fuel and also the fact that at some gas stations the required amount of gasoline is not always filled in.
