Abstract

Verfahren zum Einstellen einer Zumeßmenge eines Einspritzventils durch:
  • Einbringen einer vorbestimmten Anzahl von Drallkanälen (36) in die Drallscheibe (35),
  • Messen einer Ist-Durchflußmenge durch die bereits eingebrachten Drallkanäle (36),
  • Vergleich der gemessenen Ist- Durchflußmenge mit einer vorgegebenen Soll-Durchflußmenge, und
  • Einbringen zumindest eines weiteren Drallkanals (36), solange die gemessene Ist-Durchflußmenge kleiner als die vorgegebene Soll-Durchflußmenge ist.
