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.
