Power supply systems, injection and release
The fuel system consists of a fuel tank, топливопроводов, the filter, the fuel pump and system of injection of fuel.
The fuel tank has two chambers. The tank is located under back seats. The available stock of fuel is shown to the driver on the dashboard. And the fuel stock for each chamber 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 movement and electric signals of the lever sensor.
Ventilation of a fuel tank is carried out through the closed system of removal of air. At the petrol engine harmful pairs of gasoline gather in an adsorber and move under control in the engine.
