Abstract

Bei einem Verfahren zur Ansteuerung eines Einspritz­ ventils für eine Brennkraftmaschine, wobei eine Mag­ netspule des Einspritzventils mit einem Spannungsim­ puls beaufschlagt wird, fließt durch die Magnetspule vor dem Spannungsimpuls ein geringerer Strom, als zum Öffnen des Einspritzventils erforderlich ist. Dazu wird vorzugsweise der Magnetspule vor dem Anle­ gen des Spannungsimpulses eine pulsierende Spannung zugeführt. In a method for controlling an injection valve for an internal combustion engine, a Mag Injector net coil with a voltage im pulse is applied, flows through the solenoid before the voltage pulse a lower current than is necessary to open the injector. For this purpose, the solenoid is preferably in front of the app against the voltage pulse a pulsating voltage fed.
