Abstract

Es wird ein Verfahren zum Ermitteln oder Steuern eines Betriebsparameters einer Pumpe beschrieben, bei der die durch den Pumpvorgang der Pumpe erzeugten Druckspitzen in einem Kraftstoffspeicher gemessen werden und die Winkelposition der Druckspitze zum Ermitteln eines Betriebsparameters oder zum Steuern der Pumpe verwendet wird.

Figure 00000001
A method for determining or controlling an operating parameter of a pump is described, in which the pressure peaks generated by the pumping process of the pump are measured in a fuel reservoir and the angular position of the pressure peak is used to determine an operating parameter or to control the pump.
