Abstract
Ein Kraftstoffsystem (112) für eine Brennkraftmaschine (114) mit Kraftstoff-Direkteinspritzung umfasst eine Hochdruck-Kraftstoffpumpe (122), welche von der Brennkraftmaschine (114) mechanisch angetrieben wird, und eine Hochdruck-Hilfskraftstoffpumpe (124). Um die Integration der beiden Hochdruck-Kraftstoffpumpen (122, 124) in die Brennkraftmaschine (114) zu erleichtern, wird vorgeschlagen, dass die mechanisch angetriebene Hochdruck-Kraftstoffpumpe (122) und die Hochdruck-Hilfskraftstoffpumpe (124) eine Baueinheit (120) bilden. A fuel system (112) for a direct fuel injection engine (114) includes a high pressure fuel pump (122) mechanically driven by the engine (114) and a high pressure auxiliary fuel pump (124). In order to facilitate the integration of the two high-pressure fuel pumps (122, 124) in the internal combustion engine (114), it is proposed that the mechanically driven high-pressure fuel pump (122) and the high-pressure auxiliary fuel pump (124) form a structural unit (120).
