ABSTRACT:
In a fuel injection system for a multi-cylinder Diesel engine which is provided with magnetic valve-controlled fuel injection nozzles, and which has two fuel supply conduits (common rails) for two different groups of fuel injection nozzles and at least one high-pressure pump connected to the fuel supply conduits for delivering high-pressure fuel thereto, each fuel supply conduit includes a pressure sensor which is connected to means for shutting off the fuel supply to a fuel supply conduit when the sensor senses a pressure loss in that conduit so that the pressure can be maintained in the other fuel supply conduit and the engine can be operated on a limited basis by the cylinders supplied by the groups of injection nozzles supplied with fuel by the other fuel supply conduit.
