Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Steuerung der Kraftstoffeinspritzung in eine Brennkraftmaschine mittels zumindest eines Magnetventils, das aus einer Energieversorgungseinrichtung und einem elektrische Ladung speichernden Element versorgbar ist, das über den elektromagnetischen Verbraucher des Magnetventils nachladbar ist, wobei zumindest ein Betriebsparameter der Brennkraftmaschine erfasst wird. Es ist vorgesehen, dass in Abhängigkeit des zumindest einen Betriebsparameters der Brennkraftmaschine der Kraftstoffversorgungsdruck unter einen vorgebbaren Betriebswert reduziert wird.

Figure 00000001
The invention relates to a method and a device for controlling the fuel injection into an internal combustion engine by means of at least one solenoid valve, which can be supplied from an energy supply device and an element storing electrical charge, which can be recharged via the electromagnetic consumer of the solenoid valve, wherein at least one operating parameter of the internal combustion engine is detected becomes. It is provided that, depending on the at least one operating parameter of the internal combustion engine, the fuel supply pressure is reduced below a predeterminable operating value.
