Abstract

Die Erfindung betrifft eine Kraftstoffversorgungsanlage für eine Brennkraftmaschine mit einer den Kraftstoff aus einem Tank über eine Förderleitung zur Brennkraftmaschine fördernden Kraftstoffpumpe sowie mit einem Druckregler, der den für die Brennkraftmaschine relevanten Kraftstoffdruck wahlweise auf unterschiedliche Druckniveaus einstellt. Um Heißstartprobleme oder generell Betriebsprobleme durch Dampfblasenbildung einfach und sicher zu vermeiden, kann der Druckregler als elektronisches Druckregelventil mit integriertem Drucksensor ausgebildet sein. Alternativ ist der Druckregler in der Förderleitung angeordnet und es ist in einer vom Druckregler zum Tank führenden Rückführleitung eine Drossel vorgesehen, wobei der in der Rückführleitung stromauf der Drossel herrschende Kraftstoffdruck anstelle des bislang üblichen Atmosphärendrucks als Eingangs-Steuerdruck für den Druckregler herangezogen wird.

Figure 00000001
The invention relates to a fuel supply system for an internal combustion engine with a fuel pump which delivers the fuel from a tank via a delivery line to the internal combustion engine and with a pressure regulator which optionally adjusts the fuel pressure relevant for the internal combustion engine to different pressure levels. In order to easily and safely avoid hot start problems or general operating problems caused by the formation of vapor bubbles, the pressure regulator can be designed as an electronic pressure control valve with an integrated pressure sensor. Alternatively, the pressure regulator is arranged in the delivery line and a throttle is provided in a return line leading from the pressure regulator to the tank, the fuel pressure prevailing in the return line upstream of the throttle being used as the input control pressure for the pressure regulator instead of the previously usual atmospheric pressure.
