Power supply systems, injection and release
The fuel system consists of the fuel tank, fuel-supply lines, the filter, the fuel pump and system of injection of fuel.
The fuel tank has two cameras. The tank is located under back seats. The available reserve of fuel is shown to the driver on the dashboard. And the fuel reserve for each camera is measured by the separate sensor. The microprocessor in the block of the dashboard counts the current content of fuel on the basis of impulses of injection, speed of the movement and electric signals of the lever sensor.
Ventilation of the fuel tank is carried out through the closed system of removal of air. At the petrol engine harmful vapors of gasoline gather in an adsorber and move under control in the engine.
