Description
Die Erfindung geht aus von einer Kraftstoffversorgungseinrichtung für eine mehrzylindrige Brennkraftmaschine.The The invention is based on a fuel supply device for a multi-cylinder internal combustion engine.
Es
ist Stand der Technik (siehe z. Bsp.
Aus der Druckschrift 37 88 406 T2 ist ein Kraftstoffeinspritzsystem für eine Brennkraftmaschine bekannt, bei dem ein ungedrosselter Hochdruckbereich des Kraftstoffes zwischen einer Hochdruckpumpe und einem Ventilsitz eines Einspritzventils vorgesehen ist. Durch eine Verringerung des Hochdruckgesamtvolumens des Einspritsystems soll während eines instationären Betriebs der Brennkraftmaschine ein schnelles Ansprechen der Brennkraftmaschine erzielt werden.Out the document 37 88 406 T2 is a fuel injection system for one Internal combustion engine is known in which an unthrottled high pressure area the fuel between a high pressure pump and a valve seat an injection valve is provided. By reducing the High pressure total volume of the injection system should during a unsteady Operation of the internal combustion engine, a quick response of the internal combustion engine be achieved.
Aufgabe der Erfindung ist es daher, eine Kraftstoffversorgungseinrichtung für eine mehrzylindrige Brennkraftmaschine bereit zu stellen, bei der einerseits das für die Common Rail-Kraftstoffversorgung notwendige Speichervolumen aufgenommen werden kann, ohne daß die gemeinsame Verteilerleiste (Common Rail) aufgrund des notwendigen Kraftstoffvolumens zu Bauraumproblemen im Zylinderkopfbereich der Brennkraftmaschine führt.task The invention is therefore a fuel supply device for one multi-cylinder internal combustion engine to provide, on the one hand that for the common rail fuel supply necessary storage volume can be included without the common distribution bar (Common Rail) due to the necessary fuel volume to space problems in the cylinder head area of the internal combustion engine leads.
Die Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst.The The object is achieved by the achieved in claim 1 features.
Dadurch, daß ca. 40–70% des Kraftstoffvolumens in den beiden Zuleitungen für das Common Rail gespeichert wird, können die Injektoren versorgenden Verteilerleisten in ihren Abmessungen, insbesondere die Innendurchmesser, entsprechend kleiner dimensioniert werden.Thereby, that approx. 40-70% the fuel volume in the two supply lines for the common rail saved the injectors supplying distribution strips in their dimensions, in particular, the inner diameter, correspondingly smaller dimensions become.
In den Unteransprüchen sind weitere vorteilhafte Ausgestaltungen und Verbesserungen der erfindungsgemäßen Kraftstoffversorgungseinrichtung enthalten.In the dependent claims are further advantageous embodiments and improvements of Fuel supply device according to the invention included.
Eine vorteilhafte Entkopplung der von der Kraftstoffförderpumpe erzeugten Druckpulsationen findet über eine in einem Verteilerstück angeordnete Drossel statt.A Advantageous decoupling of the pressure pulsations generated by the fuel delivery pump takes place via a in a manifold arranged throttle instead.
Eine einfache und wirkungsvolle Reduzierung des Leitungsquerschnitts findet statt, wenn die in den beiden Ausgängen des Verteilerstückes angeordnete Drossel als Blende ausgebildet ist.A simple and effective reduction of the cable cross section takes place when the arranged in the two outputs of the distributor piece Throttle is designed as a diaphragm.
Eine vorteilhafte Funktionsintegration ergibt sich, wenn die Verteilerleiste und die Injektoren zusammen in einem Ansaugstutzen der Brennkraftmaschine integriert sind.A advantageous functional integration results when the distribution bar and the injectors together in an intake manifold of the internal combustion engine are integrated.
Der für eine mehrzylindrige Brennkraftmaschine mit Benzin-Direkteinspritzung erforderliche Kraftstoffdruck wird mit Hilfe einer Kraftstoffförderpumpe erzeugt, die mit Hilfe der Nockenwelle der Brennkraftmaschine angetrieben wird.Of the for one multi-cylinder internal combustion engine with gasoline direct injection required fuel pressure is using a fuel pump generated, which is driven by means of the camshaft of the internal combustion engine becomes.
