Abstract
Es wird ein Verfahren zum Betreiben einer Kraftstoffhochdruckpumpe einer Kraftstoffeinspritzeinrichtung einer Brennkraftmaschine vorgeschlagen, wobei die Kraftstoffhochdruckpumpe (16) wenigstens ein Pumpenelement (24) aufweist, wobei das Pumpenelement (24) einen über einen Stößel (32) zumindest mittelbar durch die Brennkraftmaschine (10) in einer Hubbewegung angetriebenen Pumpenkolben (26) aufweist, der einen Pumpenarbeitsraum (46) begrenzt, der durch ein elektrisch gesteuertes Ventil (48) mit einem Zulauf oder einem Entlastungsbereich verbindbar ist, wobei durch die Kraftstoffhochdruckpumpe (16) Kraftstoff in einen Kraftstoffhochdruckspeicher (18) gefördert wird, mit dem wenigstens ein Kraftstoffinjektor (20) verbunden ist, und wobei die Kraftstoffeinspritzeinrichtung eine elektronische Steuereinrichtung (22) aufweist, durch die das Ventil (48) und der wenigstens eine Kraftstoffinjektor (20) angesteuert werden. Beim Starten der Brennkraftmaschine (10) erfolgt während eines ersten Förderhubs oder während eines ersten Förderhubs und wenigstens eines folgenden anfänglichen Förderhubs des Pumpenkolbens (26) des wenigstens einen Pumpenelements (24) keine Kraftstoffförderung durch den Pumpenkolben (26) in den Kraftstoffhochdruckspeicher (18). Dadurch kann die Belastung der Kraftstoffhochdruckpumpe beim Starten der Brennkraftmaschine (10) gering gehalten werden.It is proposed a method for operating a high-pressure fuel pump of a fuel injection device of an internal combustion engine, wherein the high-pressure fuel pump (16) at least one pump element (24), wherein the pump element (24) via a plunger (32) at least indirectly by the internal combustion engine (10) in a stroke-driven pump piston (26) which defines a pump working chamber (46) which is connectable by an electrically controlled valve (48) with an inlet or a discharge area, wherein the fuel high-pressure pump (16) fuel in a high-pressure fuel storage (18) to which at least one fuel injector (20) is connected, and wherein the fuel injection device has an electronic control device (22) through which the valve (48) and the at least one fuel injector (20) are driven.

Vorteile der ErfindungAdvantages of the invention
Das erfindungsgemäße Verfahren zum Betreiben einer Kraftstoffhochdruckpumpe mit den Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, dass die Belastung der Kraftstoffhochdruckpumpe, insbesondere von deren Stößel, beim Starten der Brennkraftmaschine verringert ist. The inventive method for operating a high-pressure fuel pump with the features of claim 1 has the advantage that the load of the high-pressure fuel pump, in particular of the plunger, when starting the internal combustion engine is reduced.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Verfahrens angegeben. Die Anwendung des Verfahrens bei einer Kraftstoffhochdruckpumpe einer Kraftstoffeinspritzeinrichtung mit den Merkmalen des Anspruchs 5 hat den Vorteil, dass ein sicheres Starten der Brennkraftmaschine auch ohne Kraftstoffförderung durch die Kraftstoffhochdruckpumpe ermöglicht ist. Die Anwendung des Verfahrens bei einer Kraftstoffhochdruckpumpe mit einem Rollenstößel gemäß Anspruch 6 ermöglicht es, dass sich zwischen der Rolle und der Ausnehmung während des Startens der Brennkraftmaschine eine ausreichende Schmierung aufbauen kann. Die Anwendung des Verfahrens bei einer Kraftstoffhochdruckpumpe mit mehreren Pumpenelementen gemäß Anspruch 7 ermöglicht eine teilweise Kraftstoffförderung der Kraftstoffhochdruckpumpe in den Kraftstoffhochdruckspeicher und eine Verteilung der Belastung auf die verschiedenen Pumpenelemente. In the dependent claims advantageous refinements and developments of the method according to the invention are given. The application of the method in a high-pressure fuel pump of a fuel injection device with the features of claim 5 has the advantage that a safe starting of the internal combustion engine is made possible without fuel delivery by the high-pressure fuel pump. The application of the method in a high-pressure fuel pump with a roller tappet according to claim 6 makes it possible that sufficient lubrication can build up between the roller and the recess during starting of the internal combustion engine. The use of the method in a high-pressure fuel pump with a plurality of pump elements according to claim 7 allows a partial fuel delivery of the high-pressure fuel pump in the high-pressure fuel storage and a distribution of the load on the various pump elements.
