The power supply system The general data Fuel tank
The power supply system consists of a fuel tank, the fuel pump which is in a tank, and топливопроводов, and also the fuel and air filter. Systems of injection of petrol and diesel engines are described in different sections. The fuel tank - plastic, capacity 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 atmosphere through an adsorber. The adsorber is behind an internal wing of a back. The fuel reserve is shown on the panel of devices by the indicator. Thus fuel level is measured separately for each chamber by means of the lever gauge. The microprocessor in the block of the panel of devices on the basis of impulses of injection, speed of movement and electronic signals of the lever gauge counts current volume of fuel in a tank. |
