Power supply system General information Fuel tank
The power supply system consists of the fuel tank, fuel pump which is in a tank and fuel-supply lines, and also the fuel and air filter. Systems of injection of petrol and diesel engines are described in different sections. The fuel tank - plastic, with a capacity of 70 l, is fixed by collars under a back seat, before a back suspension bracket. The tank is divided into two compartments. The tank is connected with the atmosphere through an adsorber. The adsorber is behind an internal wing of a back. The reserve of fuel is shown the indicator on the dashboard. At the same time the level of fuel is measured separately for each camera by means of the lever sensor. The microprocessor in the dashboard block on the basis of impulses of injection, speed of the movement and electronic signals of the lever sensor counts the current volume of fuel in a tank. |
