Abstract

Bei einem Verfahren zum Betreiben einer Brennkraftmaschine wird eine Kraftstoffpumpe von einer Abtriebswelle der Brennkraftmaschine angetrieben. Die Kraftstoffpumpe fördert den Kraftstoff in eine Kraftstoff-Sammelleitung, von der er über mindestens eine Kraftstoff-Einspritzvorrichtung in mindestens einen Brennraum gelangt. Die Menge des von der Kraftstoffpumpe in die Kraftstoff-Sammelleitung geförderten Kraftstoffs wird durch eine Ventileinrichtung eingestellt, welche eine Druckseite der Kraftstoffpumpe wenigstens zeitweise mit einem Niederdruckbereich verbinden und von diesem trennen kann. Um auch bei hohen Drehzahlen kleinste Mengen von der Kraftstoffpumpe fördern zu können, wird vorgeschlagen, dass als Kraftstoffpumpe eine Kolbenpumpe mit mindestens einem Förderraum verwendet wird, dass eine Mehrzahl von Betriebsbereichen 1, ..., n der Brennkraftmaschine vorgesehen ist und dass wenigstens zeitweise in einem ersten Betriebsbereich der Brennkraftmaschine der Förderraum während jedes c1-ten Förderhubs und in einem n-ten Betriebsbereich der Brennkraftmaschine während jedes cn-ten Förderhubs durch die Ventileinrichtung für eine bestimmte Dauer vom Niederdruckbereich getrennt wird, wobei gilt: c1, ..., cn sind unterschiedlich.In a method for operating an internal combustion engine, a fuel pump is driven by an output shaft of the internal combustion engine. The fuel pump delivers the fuel into a fuel manifold, from which it passes through at least one fuel injection device in at least one combustion chamber. The amount of fuel delivered by the fuel pump into the fuel rail is adjusted by a valve means which can connect and disconnect a pressure side of the fuel pump at least temporarily with a low pressure region. In order to promote even at high speeds smallest amounts of the fuel pump, it is proposed that a piston pump is used with at least one pumping chamber that a plurality of operating areas 1, ..., n of the internal combustion engine is provided and that at least temporarily in a first operating range of the internal combustion engine during each c1-th delivery stroke and n-th operating range of the internal combustion engine during each cn-th delivery stroke is separated by the valve device for a certain duration from the low pressure region, where: c1, ..., cn are different.
