Abstract

Ein Kraftstoffsystem (12) für eine Brennkraftmaschine (10) umfasst einen Kraftstoffbehälter (14). Ferner ist mindestens eine Kraftstoffpumpe (16, 22) und eine Kraftstoff-Sammelleitung (26) vorgesehen. Diese wird von der Kraftstoffpumpe (22) gespeist. Mit einer Ventileinrichtung (38) kann der Druck in der Kraftstoff-Sammelleitung (26) gesteuert werden. Über mindestens eine Kraftstoff-Einspritzvorrichtung (28) gelangt der Kraftstoff in einen Brennraum (30) der Brennkraftmaschine (10). Um ein rasches Wiederanlassen einer heißen Brennkraftmaschine (10) zu ermöglichen, wird vorgeschlagen, dass die Ventileinrichtung (38) so ausgebildet ist, dass sie mindestens bei normalem Druck in der Kraftstoff-Sammelleitung (26) in nicht betätigtem Zustand geschlossen ist.
