Abstract

Die vorliegende Erfindung betrifft ein Verfahren zum Betreiben einer Brennkraftmaschine mit Direkteinspritzung in einem Kraftfahrzeug, bei dem Kraftstoff mindestens zeitweise gleichzeitig von mindestens zwei Kraftstoff-Hochdruckpumpen in mindestens eine Kraftstoffsammelleitung gefördert wird. Im normalen Betrieb der Brennkraftmaschine wird abhängig von mindestens einer Betriebsgröße der Brennkraftmaschine eine Förderung von Kraftstoff mittels einer Kraftstoff-Hochdruckpumpe ein- und/oder ausgeschaltet.
