6.1. A power supply system and injection of fuel of the petrol engine - the general information
General information
Are a part of fuel system: established in a back part of the car (under a pillow of a back seat) the fuel tank with an adsorber on absorbent carbon, fuel-supply lines, the electric fuel pump, and also the electronic system of consecutive injection operated by the control unit.
The reserve of fuel is shown to the driver on the dashboard. Gather on the petrol engine of couple of gasoline in an adsorber and move in engine combustion chambers.
Style of driving of the car has significant effect on fuel consumption. Several councils for the reasonable handling of the accelerator pedal are given below.
After start of the engine at once start even if it occurs on a frost;
At a car stop for a while more on 40 with, switch off the engine;
Move always on the highest transfer;
At the movement on long distances whenever possible support uniform speed. Avoid the movement at high speeds. Drive the car circumspectly. Without need you do not brake;
You transport the car excessive freight. If the luggage carrier is not used, remove it from a roof;
Check air pressure in tires. Do not allow excessive pressure decrease.
