Abstract
Description
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 invention
Die erfindungsgemäße Kraftstoffeinspritzeinrichtung mit den Merkmalen gemäß Anspruch 1 hat demgegenüber den Vorteil, dass von der Förderpumpe eventuell zu viel geförderter Kraftstoff bereits im Vorratsbehälter abgesteuert wird, so dass durch den Filter nur die tatsächlich von der Hochdruckpumpe angesaugte Kraftstoffmenge strömt. Der Filter kann somit entsprechend kleiner dimensioniert werden, die Betriebsdauer bis zu dessen erforderlichem Austausch kann verlängert werden und die Gefahr einer Verstopfung durch versulzten Kraftstoff ist infolge der verringerten Durchflussmenge ebenfalls verringert. Außerdem kann der Öffnungsdruck der Einlassventile der Hochdruckpumpe niedrig eingestellt werden, so dass deren maximale Fördermenge erhöht werden kann, da diese keine Verbindung mit dem Rücklauf der Förderpumpe im Vorratsbehälter aufweisen. Weiterhin kann die Hochdruckpumpe einfacher ausgebildet sein, da an dieser das Druckventil entfallen kann und auch keine Verbindungen vom Druckventil zum Rücklauf erforderlich sind.The Fuel injection device according to the invention with the features according to claim 1 has in contrast the advantage of that of the feed pump possibly too much subsidized Fuel already in the reservoir is diverted so that through the filter only the actual of the amount of fuel sucked in the high-pressure pump flows. Of the Filter can thus be dimensioned correspondingly smaller, the operating time Up to its required replacement can be extended and the danger An obstruction by spoiled fuel is due to the reduced Flow rate also reduced. In addition, the opening pressure the intake valves of the high pressure pump are set low, so that their maximum flow rate elevated This can not be connected to the return of the feed pump in the storage container exhibit. Furthermore, the high pressure pump can be made simpler be because this can be omitted the pressure valve and no Connections from the pressure valve to the return are required.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Kraftstoffeinspritzeinrichtung angegeben.In the dependent claims are advantageous embodiments and refinements of the fuel injection device according to the invention specified.
