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. The present invention relates to a method for operating a direct injection internal combustion engine in a motor vehicle, in which fuel is conveyed at least temporarily simultaneously from at least two high-pressure fuel pumps into at least one fuel manifold. In normal operation of the internal combustion engine, a delivery of fuel by means of a high-pressure fuel pump is switched on and / or off depending on at least one operating variable of the internal combustion engine.
