Title: Verfahren zum betrieb einer brennkraftmaschine
Inventor: VORBACH MARCO
IPC: F02D45/00
Filed: 2003-07-02
Abstract: Die vorliegende Erfindung betrifft ein Verfahren zum Betrieb einer Brennkraftmaschine, bei dem eine Ventilnadel eines Einspritzventils von einer Schliessposition über eine Zwischenposition zur einer Öffnungsposition und wieder zurück verstellt wird. Die Verstellung erfolgt mittels eines von einem Ansteuersignal (SA) beaufschlagten piezoelektrischen Stellglieds. Um die Verschmutzungsgefahr des Einspritzventils zu vermindern und den Verschleiss der Ventilnadel gering zu halten, weist das Ansteuersignal (SA) zur Ansteuerung des piezoelektrischen Stellglieds beim Übergang der Ventilnadel von der Schliessposition zur Zwischenposition eine grössere Flankensteilheit auf, als beim Übergang der Ventilnadel von der Zwischenposition in die Öffnungsposition.
