Abstract

Die Vorrichtung enthält einen Dosierkolben, der als Druckverstärker (1) mit einem Stufenkolben ausgebildet ist, um eine Brennstoffmenge festzulegen und auf Einspritzdruck zu bringen und mindestens ein Steuerventil (3), um eine oder mehrere Einspritzdüsen (5) mit Brennstoff zu versorgen. Der Druckverstärker (1) und das Steuerventil werden von einem elektrisch geregelten, hydraulischen System betätigt, das von einer Pumpe mit Arbeitsöl unter einem wesentlich geringeren Druck als dem Einspritzdruck beaufschlagt wird. Durch die Steuerventile (3) wird eine individuelle Einspritzung ermöglicht.
