Abstract

Verfahren zum Ansteuern eines kapazitiven Stellgliedes eines Kraftstoffeinspritzventils einer Brennkraftmaschine zur Erzielung eines konstanten Hubs, bei welchem die Bestimmung der Energiebeträge (E), welche dem Stellglied zugeführt werden, in Abhängigkeit von dem auf das Stellglied wirkenden Kraftstoffdruck (p) erfolgt.

Figure 00000001
Method for controlling a capacitive actuator of a fuel injection valve of an internal combustion engine to achieve a constant stroke, in which the energy amounts (E) which are fed to the actuator are determined as a function of the fuel pressure (p) acting on the actuator.
