Abstract

Es wird eine Kraftstoffeinspritzvorrichtung für Brennkraftmaschinen vorgeschlagen, die aus einer Kraftstoffhochdruckquelle (1) Kraftstoffeinspritzventile (9) gesteuert durch eine Steuereinrichtung (8) mit Kraftstoff versorgt. Das Kraftstoffeinspritzventil weist dabei ein Einspritzventilglied (14) auf, dessen Öffnungs- oder Schließstellung durch einen dieses Einspritzventilglied beaufschlagenden in einem Steuerraum (24) eingestellten Druck bestimmt wird. Dazu muß zur Durchführung einer Einspritzung der Druck im Steuerraum (24) entlastet werden, was mit einem Steuerventil (31) erzielt wird, das sequentiell zwei unterschiedliche Abschlußquerschnitte eines Abflußkanals (49) des Steuerraums (24) nacheinander aufsteuert. Damit ist es möglich, eine angepaßte Öffnung des Kraftstoffeinspritzventilglieds für eine Vor- und eine Haupteinspritzung zu bewirken.
