Abstract

Beschrieben wird ein Verfahren zum Betrieb einer Brennkraftmaschine insbesondere eines Kraftfahrzeugs, bei dem eine Kraftstoffpumpe (13) eine Fördermenge Kraftstoff aus einem Kraftstoffspeicher (11) mit einem Vordruck zu einer Zumesseinheit (15) pumpt, wobei die Zumesseinheit (15) eine Hochdruckpumpe (16) mit einer Kraftstoffmenge versorgt, die von der Zumesseinheit (15) in Abhängigkeit einer Ansteuergröße (A_Z) eingestellt wird.A method for operating a is described Internal combustion engine, in particular of a motor vehicle, at a fuel pump (13) has a delivery rate of fuel from a fuel reservoir (11) with a pre-pressure a metering unit (15) pumps, the metering unit (15) a high pressure pump (16) with a fuel quantity supplied by the metering unit (15) depending a control variable (A_Z) is set.

Die Kraftstoffpumpe (13) wird in Abhängigkeit der Ansteuergröße (A_Z) der Zumesseinheit (15) angesteuert, um die Pumpenleistung an den Betriebspunkt der Brennkraftmaschine anzupassen und die mittlere Belastung der Kraftstoffpumpe (13) dadurch zu senken.

Figure 00000001
The fuel pump (13) is controlled as a function of the control variable (A_Z) of the metering unit (15) in order to adapt the pump output to the operating point of the internal combustion engine and thereby reduce the average load on the fuel pump (13).
