Abstract
Fuel injection system having a feed pump by which fuel is pumped out of a fuel tank to the intake side of a high-pressure pump pumps fuel into a reservoir as a function of engine operating parameters. A fuel metering device is provided for adjusting the fuel quantity pumped into the reservoir by the high-pressure pump. An electrically actuated blocking valve is disposed between the feed pump and the high-pressure pump, and by means of this valve the high-pressure pump can be disconnected completely from the feed pump. By means of the blocking valve, it can still be attained that no fuel is pumped by the high-pressure pump even if the fuel metering device does not provide complete sealing.
