Description
Die vorliegende Erfindung betrifft eine Kraftstoffsammelschiene für einen Verbrennungsmotor. Die vorliegende Erfindung betrifft darüber hinaus ein entsprechendes Herstellungsverfahren für eine Kraftstoffsammelschiene sowie einen entsprechenden Verbrennungsmotor.The present invention relates to a fuel rail for an internal combustion engine. The present invention also relates to a corresponding manufacturing method for a fuel rail and a corresponding internal combustion engine.
Unter dem Begriff der Common-Rail- oder Speichereinspritzung werden in der Kraftfahrzeugtechnik Einspritzsysteme für Verbrennungsmotoren zusammengefasst, bei denen eine Hochdruckpumpe den Kraftstoff bei Motorbetrieb in ein Rohrleitungssystem presst. An diesem als Kraftstoffsammelschiene (rail) dienenden Verteilerrohr sind Einspritzdüsen (Injektoren) zur Versorgung der Zylinder mit Kraftstoff angeschlossen.In automotive engineering, the term "common rail" or "accumulator injection" combines injection systems for internal combustion engines, in which a high-pressure pump presses the fuel into a pipeline system during engine operation. In this serving as a fuel rail (rail) manifold injection nozzles (injectors) are connected to supply the cylinder with fuel.
Grundsätzlich bekannt ist es aus
Die Erfindung stellt eine Kraftstoffsammelschiene für einen Verbrennungsmotor, ein entsprechendes Herstellungsverfahren für eine Kraftstoffsammelschiene sowie einen entsprechenden Verbrennungs-, insbesondere Dieselmotor gemäß den unabhängigen Ansprüchen bereit.The invention provides a fuel rail for an internal combustion engine, a corresponding fuel rail production method, and a corresponding combustion engine, especially a diesel engine, according to the independent claims.
Ein Vorzug dieser Lösung liegt in der bauraumgerechten, funktionsintegrierten und strömungsoptimierten Konstruktion der erfindungsgemäßen Kraftstoffsammelschiene unter Entfall der bei herkömmlichen Einspritzsystemen unabdingbaren Lötprozesse.An advantage of this solution lies in the space-compatible, function-integrated and flow-optimized construction of the fuel rail according to the invention, with the elimination of the soldering processes which are indispensable in conventional injection systems.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Patentansprüchen angegeben. So kann das (doppelwandige) Rohr der Kraftstoffsammelschiene mit einem Pulver gefüllt werden. Durch diese einfache bauliche Maßnahme wird eine Dämpfung und Verbesserung der akustischen Eigenschaften erzielt, die insbesondere der Reduzierung mechanischer Geräusche durch die Injektoren oder aufgrund von Druckpulsationen dient.Further advantageous embodiments of the invention are specified in the dependent claims. Thus, the (double-walled) tube of the fuel rail can be filled with a powder. By means of this simple construction measure, damping and improvement of the acoustic properties are achieved, which in particular serve to reduce mechanical noises through the injectors or due to pressure pulsations.
