Abstract

Ein Common-Rail-Kraftstoffeinspritzsystem besitzt eine Kraftstoffpumpe (11), eine Common-Rail (20) und eine Einspritzvorrichtung (23). Die Einspritzvorrichtung spritzt Hochdruckkraftstoff, der von der Common-Rail zugeführt wird, in einen Verbrennungsmotor ein und lässt einen Teil des Hochdruckkraftstoffs entweichen. Eine elektronische Steuereinheit (ECU) (50) begrenzt eine Wärmemenge des entweichenden Kraftstoffs der Einspritzvorrichtung, basierend auf einer Restmenge des in einem Kraftstofftank (10) befindlichen Kraftstoffs. Zu diesem Zeitpunkt wird ein Zielwert des in der Common-Rail vorherrschenden Kraftstoffdrucks auf einen niedrigeren Wert geändert und die Begrenzung des Kraftstoffdrucks wird mit dem geänderten Zielwert durchgeführt. Somit kann eine Verringerung des erzeugten Drehmoments des Verbrennungsmotors entgegen der Absicht eines Fahrers verhindert werden, während die Bauteile wie beispielsweise das Kraftstoffeinspritzventil geschützt werden.
