Abstract
Description
Die Erfindung betrifft eine Kraftstoffeinspritzvorrichtung für eine Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1.The The invention relates to a fuel injection device for an internal combustion engine according to the preamble of claim 1.
Eine
derartige Kraftstoffeinspritzvorrichtung mit einem Kraftstoffverteiler
ist aus der
Die erfindungsgemäße Kraftstoffeinspritzvorrichtung für eine Brennkraftmaschine mit den kennzeichnenden Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, dass der mindestens eine in einem Ring gehaltene Filter bei der Montage in den Innenraum des Kraftstoffverteilers vor Beschädigungen geschützt ist, wobei der Ring mittels einer Presspassung im zylinderförmigen Innenraum des Kraftstoffverteilers gehalten ist.The Fuel injection device according to the invention for one Internal combustion engine with the characterizing features of the claim 1 has in contrast the advantage that the at least one held in a ring filter during installation in the interior of the fuel rail from damage protected is, wherein the ring by means of a press fit in the cylindrical interior the fuel distributor is held.
Vorteilhafterweise wird mittels der Presspassung eine flüssigkeitsdichte Abdichtung zwischen dem Ring und dem zylinderförmigen Innenraum geschaffen, so dass auf zusätzliche Dichtungen verzichtet werden kann und der Kraftstoff ausschließlich vom Zulauf über den Filter zu den Anschlüssen strömen kann, wodurch die Betriebssicherheit der Kraftstoffeinspritzvorrichtung gesteigert werden kann.advantageously, becomes a fluid-tight seal by means of the press fit created between the ring and the cylindrical interior, so on extra Seals can be dispensed with and the fuel exclusively from Inlet over the filter to the terminals stream can, thereby improving the operational safety of the fuel injector can be increased.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Kraftstoffeinspritzvorrichtung für eine Brennkraftmaschine möglich.By in the subclaims listed activities are advantageous developments and improvements in the claim 1 specified fuel injection device for an internal combustion engine possible.
Zur Verbesserung der konstruktiven Ausführung des Kraftstoffverteilers bezüglich der Trennung des Zulaufs von den Anschlüssen sind entsprechend der Anordnung der Anschlüsse zum Zulauf ein oder zwei in Ringen gehaltene Filter im Innenraum angeordnet. Vorteilhafterweise ist der Einsatz der in Ringen gehaltenen Filter unabhängig von der Anordnung des Zulaufs zu den Anschlüssen, so dass bei einer Anordnung der Anschlüsse nur auf einer Seite des Zulaufs entlang einer Längsachse des Kraftstoffverteilers ein einziger Filter zwischen dem Zulauf und den Anschlüssen und bei einer Anordnung der Anschlüsse auf beiden Seiten des Zulaufs entlang der Längsachse jeweils ein Filter zwischen dem Zulauf und den Anschlüssen auf der einen Seite des Zulaufs und auf der anderen Seite des Zulaufs im Innenraum des Kraftstoffverteilers vorgesehen werden können, wodurch der in einem Ring gehaltene Filter bei verschiedensten Kraftstoffverteilern eingesetzt werden kann.to Improvement of the design of the fuel rail in terms of the separation of the inlet from the connections are according to the Arrangement of connections to the inlet one or two held in rings filter in the interior arranged. Advantageously, the insert is held in rings Filter independent from the arrangement of the inlet to the terminals, so that in one arrangement the connections only on one side of the inlet along a longitudinal axis of the fuel rail a single filter between the inlet and the ports and in an arrangement of the connections one filter on each side of the inlet along the longitudinal axis between the inlet and the connections on one side of the Inlet and on the other side of the inlet in the interior of the fuel rail can be provided, which the held in a ring filter in a variety of fuel manifolds can be used.
Zur weiteren Verbesserung der konstruktiven Ausführung des Kraftstoffverteilers sind beide Filter jeweils in einem Ring gehalten und die Ringe über eine radial vom zylinderförmigen Innenraum beabstandeten und mit mindestens einer Verbindungsöffnung versehene Hülse miteinander verbunden. Vorteilhafterweise sind die beiden Filter, die beiden Ringe und die eine Hülse als ein gemeinsames Bauteil ausgeführt, so dass die Filter in einem einzigen Arbeitsgang in den Kraftstoffverteiler montiert werden können, wodurch der Montageaufwand gesenkt und Montagefehler ausgeschlossen werden können.to further improvement of the design of the fuel rail Both filters are each held in a ring and the rings over a radially from the cylindrical one Interior spaced and provided with at least one connection opening Sleeve together connected. Advantageously, the two filters, the two Rings and the one sleeve executed as a common component, so the filters in a single operation can be mounted in the fuel rail, thereby the assembly effort is reduced and assembly errors are excluded can.
Zur weiteren Verbesserung der konstruktiven Ausführung des Kraftstoffverteilers sind die Filter in Form von Filterpatronen ausgeführt. Vorteilhaft ist dabei, dass bei einer großen Filterfläche der Filterpatronen die Maschenweite eng gewählt werden kann, so dass sich bei einer hohen Partikelspeicherfähigkeit sehr kleine Partikel in der Filterpatrone aufgefangen werden kann, wodurch eine lange Lebensdauer der Filter bei einer hohen Betriebssicherheit der Kraftstoffeinspritzvorrichtung erreicht wird.to further improvement of the design of the fuel rail the filters are designed in the form of filter cartridges. Advantageous is going to be that at a big one filter area the filter cartridges, the mesh size can be narrow, so that with a high particle storage capacity very small particles can be trapped in the filter cartridge, creating a long Life of the filter with a high reliability of the fuel injection device is reached.
Zur weiteren Verbesserung der konstruktiven Ausführung des Kraftstoffverteilers sind die Filterpatronen in der Hülse aufgenommen. Vorteilhafterweise ragen die Filterpatronen in den Hülsen hinein, so dass bei der Montage der Filter die Filter nicht beschädigt werden können, wodurch die Betriebssicherheit der Kraftstoffeinspritzvorrichtung gesteigert werden kann.to further improvement of the design of the fuel rail are the filter cartridges in the sleeve added. Advantageously, the filter cartridges protrude into the sleeves into it, so that with the assembly of the filters the filters are not damaged can, whereby the operational safety of the fuel injection device can be increased.
