ABSTRACT:
A fuel supply system with two series-connected pumps and fuel injection valves that inject fuel directly into a combustion chamber of an engine. The system includes a relief device. In a simple embodiment, the relief device can assure that the pressure in the pressure line can drop when the engine has been shutoff. The relief line may, however, also be embodied such that during the entire time of engine operation, the pressure in the pressure line can be lowered at any time as needed. The apparatus and the method are intended for an internal combustion engine of a vehicle.
