Abstract

Die Erfindung betrifft ein Verfahren zum Steuern eines Kraftstoff-Einspritzsystems für eine Brennkraftmaschine, insbesondere für ein Kraftfahrzeug, mit einem Absteuerventil , welches zum Aufbauen eines Einspritzdruckes in einem Hochdruckraum zwischen einer Hochdruckpumpe und einer Einspritzdüse einen Kraftstoffzulauf wahlweise mit dem Hochdruckraum verbindet, wobei ein Einspritzsteuersignal das Absteuerventil für eine vorbestimmte erste Zeitspanne schließt und anschließend wieder öffnet. Hierbei schließt nach dem Einspritzsteuersignal wenigstens ein weiteres Steuersignal das Absteuerventil für wenigstens eine vorbestimmte zweite Zeitspanne ganz oder teilweise.
