Abstract
Die Kraftstoffeinspritzeinrichtung für eine Brennkraftmaschine weist eine Kraftstoffhochdruckpumpenvorrichtung (14) auf, durch die Kraftstoff unter Hochdruck zu zwei Kraftstoffhochdruckspeichern (18, 20) gefördert wird, mit denen jeweils zumindest ein Injektor (22) verbunden ist, durch den Kraftstoff an einem Zylinder der Brennkraftmaschine eingespritzt wird. Die Kraftstoffhochdruckpumpenvorrichtung (14) ist über jeweils eine hydraulische Leitung (32, 33) direkt mit den beiden Kraftstoffhochdruckspeichern (18, 20) verbunden. Die beiden Kraftstoffhochdruckspeicher (18, 20) sind durch eine weitere hydraulische Leitung (34) direkt miteinander verbunden.The fuel injection device for an internal combustion engine has a high-pressure fuel pump device (14) through which fuel is delivered under high pressure to two high-pressure fuel reservoirs (18, 20), to which at least one injector (22) is connected, injected by the fuel to a cylinder of the internal combustion engine becomes. The high-pressure fuel pump device (14) is connected via a respective hydraulic line (32, 33) directly to the two high-pressure fuel accumulators (18, 20). The two high-pressure fuel accumulators (18, 20) are directly connected to each other by a further hydraulic line (34).
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Kraftstoffeinspritzeinrichtung für eine Brennkraftmaschine nach der Gattung des Anspruchs 1.The The invention is based on a fuel injection device for an internal combustion engine according to the preamble of claim 1.
Eine
solche Kraftstoffeinspritzeinrichtung ist durch die
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Kraftstoffeinspritzeinrichtung mit den Merkmalen gemäß Anspruch 1 hat demgegenüber den Vorteil, dass statt des gemeinsamen Hochdruckraums an der Kraftstoffhochdruckpumpe wie beim Stand der Technik nur die weitere hydraulische Leitung erforderlich ist, die kostengünstig ist und deren Platzbedarf gering ist. Durch die die beiden Kraftstoffhochdruckspeicher verbindende hydraulische Leitung ist sichergestellt, dass in beiden Kraftstoffhochdruckspeichern zumindest annähernd dieselben Druckverhältnisse herrschen.The Fuel injection device according to the invention with the features of claim 1 has the other hand the advantage that instead of the common high-pressure chamber to the high-pressure fuel pump As in the prior art, only the further hydraulic line is required, which is inexpensive and their space requirements is low. By connecting the two high-pressure fuel storage hydraulic line is ensured that in both high-pressure fuel tanks at least approximately the same pressure conditions to rule.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Kraftstoffeinspritzeinrichtung angegeben. Die Ausbildung gemäß Anspruch 2 ermöglicht eine einfache Ausbildung der Kraftstoffhochdruckpumpe, da an dieser keine Zusammenführung der Auslässe der beiden Pumpenelemente erforderlich ist.In the dependent claims are advantageous embodiments and further developments of the fuel injection device according to the invention specified. The training according to claim 2 allows a simple design of the high-pressure fuel pump, because of this no merging of the outlets of the two Pump elements is required.
