Abstract

Es wird ein Kraftstoffeinspritzsystem mit einem HC-Injektor (16) vorgeschlagen, bei dem der Förderdruck einer Vorförderpumpe (5) zur Kraftstoffversorgung des HC-Injektors (16) herangezogen wird. Wenn der HC-Injektor (16) Kraftstoff in den Abgasstrang der Brennkraftmaschine einspritzt, wird der Druck im Niederdruckbereich des Kraftstoffeinspritzsystems kurzzeitig angehoben.
