Abstract

Das Einspritzsystem für die lastabhängige Einspritzung des Brennstoffes in einen Zylinder eines Dieselmotors in zwei Teileinspritzungen, einer Voreinspritzung (V) und einer Haupteinspritzung (H), ist so ausgelegt, dass bei kleinen Lasten - unter beispielsweise 20 - 50% der Voll-Last - keine Aufteilung der eingespritzten Brennstoffmenge auf die Vor­ einspritzung (V) und die Haupteinspritzung (H) erfolgt. Damit werden bei den geringen Gesamtbrennstoffmengen, die bei kleinen Lasten benötigt werden, Unregelmässigkeiten in der Brennstoffeinspritzung verhindert.
