Abstract
Description
Die Erfindung betrifft eine Kraftstoffversorgungseinrichtung nach dem Oberbegriff des Anspruchs 1.The The invention relates to a fuel supply device according to Preamble of claim 1.
Aus
der Offenlegungsschrift
Problematisch in solchen Systemen ist, dass vorlaufgetriebene und/oder rücklaufgetriebene Saugstrahlpumpen eine ausreichende Größe aufweisen müssen, dass in jedem Betriebszustand eine zur Kühlung ausreichende Menge Kraftstoff gefördert werden kann. Weiterhin ist die Stromaufnahme der Kraftstoffpumpen relativ hoch.Problematic in such systems, it is flow-driven and / or return-driven suction jet pumps have a sufficient size have to, that in each operating condition sufficient for cooling amount of fuel be encouraged can. Furthermore, the power consumption of the fuel pump is relative high.
Der Erfindung liegt die Aufgabe zugrunde, eine Kraftstoffversorgungseinrichtung anzugeben, mit der die Nachteile des Standes der Technik vermindert werden können.Of the Invention is based on the object, a fuel supply device indicate that reduces the disadvantages of the prior art can be.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The The object is achieved by the Characteristics of claim 1 solved.
Bei einer erfindungsgemäßen Kraftstoffversorgungseinrichtung zur Kraftstoffversorgung einer Brennkraftmaschine sind wenigstens eine erste und eine zweite elektronisch geregelte Kraftstoffpumpe vorgesehen, die Kraftstoff aus einem Kraftstoff-Vorratsbehälter über eine Vorlaufleitung zur Brennkraftmaschine befördern. Erfindungsgemäß steht jede Kraftstoffpumpe mit wenigstens einer separaten Saugstrahlpumpe in Antriebsverbindung. Da die Fördermenge der einzelnen Kraftstoffpumpen durch das Vorsehen wenigstens zweier elektronisch geregelter Kraftstoffpumpen reduziert ist, kann die Größe der Saugstrahlpumpen vorteilhaft beschränkt bleiben. Trotzdem ist die Menge des geförderten Kraftstoffes zur Kühlung in jedem Betriebszustand ausreichend. Gleichzeitig ist eine Erhöhung der maximalen Förderleistung möglich. Weiterhin ist eine Verringerung der Stromaufnahme möglich.at a fuel supply device according to the invention for the fuel supply of an internal combustion engine are at least a first and a second electronically controlled fuel pump provided the fuel from a fuel reservoir via a flow line to Transport internal combustion engine. According to the invention each fuel pump with at least one separate suction jet pump in drive connection. As the flow rate the individual fuel pump by providing at least two electronically controlled fuel pumping is reduced, the Size of the suction jet pumps advantageously limited stay. Nevertheless, the amount of fuel delivered for cooling in sufficient for every operating condition. At the same time is an increase in maximum capacity possible. Furthermore, a reduction in power consumption is possible.
Günstige Ausgestaltungen und Vorteile der Erfindung sind der Beschreibung sowie den weiteren Ansprüchen zu entnehmen.Cheap designs and advantages of the invention are the description and the other claims remove.
Besonders vorteilhaft werden die genannten Vorteile erreicht, wenn jede Saugstrahlpumpe von der jeweiligen Kraftstoffpumpe unabhängig antreibbar ist.Especially Advantageously, the advantages mentioned are achieved when each suction jet pump can be driven independently of the respective fuel pump.
Die zweite elektronisch geregelte Kraftstoffpumpe weist vorzugsweise eine separate Vorlaufleitung innerhalb des Kraftstoff-Vorratsbehälters auf. Dadurch kann eine Fördermenge der einzelnen Kraftstoffpumpen in allen Betriebszuständen vermindert werden. Durch die verminderte Fördermenge ist die Stromaufnahme der einzelnen Kraftstoffpumpen geringer und ein Wärmeeintrag jeder Kraftstoffpumpe in den Kraftstoff reduziert. Dies erlaubt eine Vergrößerung der maximalen Systemleistung.The second electronically controlled fuel pump preferably has a separate flow line within the fuel tank. Thereby can be a flow rate the individual fuel pump reduced in all operating conditions become. Due to the reduced flow rate the current consumption of the individual fuel pumps is lower and a heat input every fuel pump is reduced in the fuel. This allows an enlargement of the maximum system performance.
Bevorzugt ist in jeder Vorlaufleitung ein separates Rückschlagventil angeordnet. Damit kann bewirkt werden, dass jede der Kraftstoffpumpen unabhängig von der oder den anderen eine Saugstrahlpumpe antreiben kann.Prefers a separate check valve is arranged in each flow line. This can cause each of the fuel pumps to be independent of the one or the other can drive a suction jet pump.
Es ist günstig, wenn die Vorlaufleitungen vor einem Kraftstofffilter zusammengeführt sind. Damit kann die Reinigungskapazität eines gemeinsamen Kraftstofffilters trotz separater Vorlaufleitungen der Kraftstoffpumpen ausgenutzt werden.It is cheap, when the supply lines are brought together in front of a fuel filter. This can reduce the cleaning capacity a common fuel filter despite separate supply lines the fuel pumps are exploited.
In einer günstigen Ausgestaltung ist stromauf vor dem jeweiligen Rückschlagventil ein Anschluss für eine oder mehrere Saugstrahlpumpen vorgesehen. Die Zahl der Saugstrahlpumpen kann den jeweiligen Gegebenheiten angepasst werden. Ein Antrieb der Saugstrahlpumpen ist durch die Verschaltung sichergestellt.In a cheap one Embodiment upstream of the respective check valve is a connection for one or more suction jet pumps provided. The number of suction jet pumps can be adapted to the respective circumstances. A drive The suction jet pump is ensured by the interconnection.
Eine vorteilhafte Verringerung der Anzahl von Komponenten ist möglich, wenn die Kraftstoffpumpen ein gemeinsames Steuergerät aufweisen. Es ist jedoch auch möglich, für jede Kraftstoffpumpe ein separates Steuergerät vorzusehen.A Advantageous reduction in the number of components is possible if the fuel pumps have a common control unit. However, it is also possible, for every Fuel pump to provide a separate control unit.
Im Folgenden wird die Erfindung anhand eines in der Zeichnung beschriebenen Ausführungsbeispiels näher erläutert. Die Zeichnung, die Beschreibung und die Ansprüche enthalten zahlreiche Merkmale in Kombination, die der Fachmann zweckmäßigerweise auch einzeln betrachten und zu sinnvollen weiteren Kombinationen zusammenfassen wird.in the The invention will be described below with reference to a drawing embodiment explained in more detail. The The drawing, the description and the claims contain numerous features in combination, which the skilled person expediently consider individually and sum up to meaningful further combinations.
