Abstract

Eine Kraftstoffdrucksteuereinrichtung für eine Zylindereinspritzverbrennungsmaschine, die in der Lage ist, die Maschine ohne Ausfall neu zu starten trotz des Ansteigens des Kraftstoffdrucks bedingt durch Temperaturanstieg unmittelbar nach dem Anhalten des Maschinenbetriebs. Der Kraftstoff wird von einer Hochdruckkraftstoffpumpe 5 zu einer Kraftstoffzufuhrleitung 2 zugeführt, um durch Kraftstoffventile 1 in Verbrennungskammern 20 von Zylindern eingespritzt zu werden. Eine ECU 10 schätzt eine Zunahme DELTAP des Kraftstoffdrucks PF innerhalb der Kraftstoffzufuhrleitung 2 nach Anhalten des Maschinenbetriebs, basierend auf einer Wassertemperatur THW und einer Ansaugtemperatur THA, zum Einschränken eines Maximalwertes Po derart, dass ein Summenwert PM des gewünschten Kraftstoffdrucks Po und die Zunahme DELTAP nicht den kritischen Betätigungsdruck Pi des Kraftstoffeinspritzventils 1 übersteigen.
