Abstract: A device is provided for preventing the engine from stalling in a vehicle equipped with a diesel injection system, particularly a common-rail injection system. The device comprises a volume flow control valve, a high-pressure fuel pump, a pressure control valve, one or more injectors and a control unit. The control unit carries out a pressure control by controlling the volume pressure control valve in the idle state of the engine in a first operating mode, monitors whether a working point is present at which a release of air from the fuel is carried out and, in the event such a working point is detected, initiates a second operating mode in which a pressure control is carried out by controlling the pressure control valve.
