摘要

A device for the prevention of die-back of the motor in the case of a fuel injection system with a this flax vehicle equipped with a volumetric flow control valve (9), a fuel - high-pressure pump (4), a pressure regulating valve (17), one or more injectors (2) and a control unit (12), characterized in that the control unit (12) in the idling operation of the engine in a first operating mode is a pressure control exclusively by a regulation of the volumetric flow control valve (9), in this first operating mode monitors whether an operating point is present, in which a triggering of air from the fuel occurs, and in the case of the detecting of such a working point a second operating mode, in which a pressure regulation by means of a control of the pressure regulating valve (17) takes place.
