Control Valve, fuel quantity (common rail system) - V46-11-0013 VEMO

To supply fuel to the power unit of vehicles, such a small but very important element as a fuel quantity valve is used. As a rule, at first glance, the signs of a malfunction are invisible. Therefore, it is often not possible to detect a breakdown in the early stages. However, the failure of the fuel quantity valve leads to serious consequences. The pressure of the fuel exceeds the norm, because there is no control. This leads to a break in the hoses.

The functionality of a control valve

The VEMO brand Control Valve, fuel quantity (common rail system) is represented by a vacuum valve. Although the general structure of the device is a body with this very valve, as well as with a spring and a membrane. It has three holes. Two - for the output of fuel, the third - for supply to the intake manifold. As the engine revs up, fuel consumption rises significantly. As a result, a vacuum is created in the third output. It collects the spring and lifts the membrane. The valve in the fuel quantity valve opens slightly. With sufficient pressure, the check valve directs fuel into the tank through a special return hose.
