Abstract

Die Erfindung betrifft ein Kraftstoff-Versorgungssystem für eine mit Kraftstoffdirekteinspritzung arbeitende Brennkraftmaschine, nahe derer eine Kraftstoff-Hochdruckpumpe angeordnet ist, die von einer einem Kraftstofftank zugeordneten Förderpumpe mit Kraftstoff versorgt wird und wobei aus dem zwischen Hochdruckpumpe und Brennkraftmaschine liegenden Hochdruckabschnitt des Kraftstoff-Versorgungssystemes eine Kraftstoff-Leckmenge und/oder Kraftstoff-Spülmenge abgezweigt wird. Erfindungsgemäß wird zumindest ein Teil der Leckmenge oder Spülmenge mittels einer weiteren Kraftstoffpumpe der Vorlaufseite der Hochdruckpumpe zugeführt. Bevorzugt wird dabei die Leckmenge und/oder Spülmenge über eine geeignete Drosselstelle und/oder ein Druckbegrenzungsventil oder Druckregelventil begrenzt.
