Abstract

The crankcase (1) comprises a cast gate in the V-angle, serving as a bracket (3) for fastening of the pump plug housing (2). The bracket has threaded bores (4) for clamping bolts (5) of the pump plug casing. The bracket has also plain bores (7). They may connect a main oil flow duct (8) of the crankcase to the lubrication bores (9) of the pump plug casing.

Description

Die Erfindung bezieht sich auf eine Befestigung eines Steckpumpengehäuses an einem Kurbelgehäuse eines V-Motors.The invention relates to an attachment of a plug-in pump housing on a Crankcase of a V-engine.

Zur Erzielung höherer Einspritzdrücke geht man dazu über die Reiheneinspritzpumpen durch Einsteckpumpen zu ersetzen. Da man Kosten sparen möchte ist man bestrebt, die Einsteckpumpengehäuse direkt auf einem Kurbelgehäuse von in Serie befindlichen Brennkraftmaschinen zu befestigen.To achieve higher injection pressures, one goes over the in-line injection pumps to be replaced by plug-in pumps. Since you want to save costs, you endeavor to the plug-in pump housings directly on a crankcase from series Attach internal combustion engines.

Der Erfindung liegt die Aufgabe zugrunde ein Steckpumpengehäuse so auf einem Kur­ belgehäuse einer schon in Serie befindlichen Brennkraftmaschine zu befestigen, daß die Änderungen am Kurbelgehäuse minimal sind, und daß nach wie vor die Anbrin­ gung konventioneller Reiheneinspritzpumpen anstelle der Steckpumpen möglich ist.The invention has for its object a plug-in pump housing so on a course to fix a housing already internal combustion engine that the changes to the crankcase are minimal, and that still the mounting conventional in-line injection pumps instead of plug-in pumps is possible.

Gelöst wird diese Aufgabe dadurch, daß das Kurbelgehäuse in seinem V-Winkel einen Anguß aufweist, welcher als Konsole zur Befestigung des Steckpumpengehäuses fun­ giert, daß die Konsole Gewindebohrungen zur Aufnahme von Befestigungsschrauben des Steckpumpengehäuses aufweist, und daß die Konsole mit einer Bohrung ver­ sehen ist, welche einen Hauptölstromkanal des Kurbelgehäuses mit Schmieröl­ bohrungen der Steckpumpen verbinden.This problem is solved in that the crankcase has a V-angle Sprue has, which fun as a console for attaching the plug-in pump housing yaw that the console tapped holes for receiving fastening screws of the plug-in pump housing, and that the console ver with a bore see which is a main oil flow channel of the crankcase with lubricating oil Connect the holes in the plug-in pumps.

Durch die Erfindung wird erreicht, daß das Kurbelgehäuse einer in Serie befindlichen Brennkraftmaschine lediglich eines Angusses bedarf, der als Konsole für die Befesti­ gung des Steckpumpengehäuses dient, ansonsten kann das Kurbelgehäuse unverändert bleiben. Falls geringere Anforderungen an die Abgasqualität gestellt werden ist es weiterhin möglich eine konventionelle Reiheneinspritzpumpe zu verwenden, da die ur­ sprüngliche Befestigungsart dieser Reiheneinspritzpumpe am Kurbelgehäuse von der Konsole unbeeinflußt bleibt.The invention ensures that the crankcase is one in series Internal combustion engine only needs a sprue, which acts as a bracket for the fasteners  supply of the plug-in pump housing is used, otherwise the crankcase can remain unchanged stay. If there are lower exhaust gas quality requirements, it is it is still possible to use a conventional in-line injection pump because the original Original mounting method of this in-line injection pump on the crankcase from Console remains unaffected.

Ein weiterer Vorteil der Erfindung ist darin zu sehen, daß die Nockenwelle der Ein­ steckpumpe vom gleichen Rädertrieb antreibbar ist wie die Nockenwelle der ursprüng­ lich vorgesehenen Reiheneinspritzpumpe. Ferner kann die Einsteckpumpe über eine Bohrung in der Konsole auf einfache Art und Weise an den Schmierölkreislauf der Brennkraftmaschine angeschlossen werden.Another advantage of the invention is the fact that the camshaft of the one plug-in pump can be driven by the same gear train as the camshaft of the original In-line injection pump. Furthermore, the plug-in pump can Drilling in the console in a simple way to the lubricating oil circuit of the Internal combustion engine can be connected.

Ein Ausführungsbeispiel der Erfindung ist in einer Zeichnung dargestellt.An embodiment of the invention is shown in a drawing.

Die Zeichnung zeigt im Querschnitt einen Ausschnitt aus einem Kurbelgehäuse 1 im Bereich eines V-Winkels, der als V-Motor ausgebildeten Brennkraftmaschine. Auf dem Kurbelgehäuse 1 ist ein Steckpumpengehäuse 2 einer Einsteckpumpe befestigt. Zur Befestigung ist das Kurbelgehäuse 1 mit einem Anguß versehen, der eine Kon­ sole 3 bildet. Die Konsole 3 ist mit Gewindebohrungen 4 versehen, in welche Befesti­ gungsschrauben 5 eingeschraubt sind, die das Steckpumpengehäuse 2 fest mit der Konsole 3 verbinden. Die Lage des Steckpumpengehäuses 2 gegenüber der Konsole 3 wird durch Zylinderpaßstifte 6 fixiert. Zum Zwecke der Ölversorgung der Steckpum­ pen weist die Konsole 3 Bohrungen 7 auf, welche einen Hauptölstromkanal 8 der Brennkraftmaschine über Schmierölbohrungen 9 im Steckpumpengehäuse 2 mit den Steckpumpen 10 verbinden. The drawing shows in cross section a section of a crankcase 1 in the area of a V-angle, the internal combustion engine designed as a V-engine. A plug-in pump housing 2 of a plug-in pump is fastened on the crankcase 1 . To attach the crankcase 1 is provided with a sprue that forms a con sole 3 . The console 3 is provided with threaded holes 4 , in which fastening screws 5 are screwed, which firmly connect the plug-in pump housing 2 with the console 3 . The position of the plug-in pump housing 2 relative to the bracket 3 is fixed by cylinder dowel pins 6 . For the purpose of supplying oil to the plug-in pumps, the console has 3 holes 7 which connect a main oil flow channel 8 of the internal combustion engine via lubricating oil holes 9 in the plug-in pump housing 2 to the plug-in pumps 10 .

Eine Nockenwelle 11 der Einsteckpumpe kann vom gleichen Rädertrieb wie die kon­ ventionelle Reiheneinspritzpumpe angetrieben werden. Auf eine explizite Darstellung des Rädertriebes wurde verzichtet.A camshaft 11 of the plug-in pump can be driven by the same gear train as the conventional in-line injection pump. The wheel drive was not explicitly shown.

Die Erfindung gestattet den Anbau der Steckpumpe, ohne daß das in Serienfertigung befindlichen Kurbelgehäuse wesentlich abgeändert zu werden braucht. Das Kurbelge­ häuse 1 wird lediglich mit einem Anguß versehen, der als Konsole 3 dient.The invention permits the installation of the plug-in pump without the crankcase, which is in series production, having to be significantly modified. The crankcase 1 is only provided with a sprue that serves as a console 3 .

Für die Fall, daß geringere Anforderungen an die Abgasqualität gestellt werden, kann nach wie vor eine konventionelle Reiheneinspritzpumpe anstelle der Einsteckpumpen angebracht werden, da die Konsole 3 der üblichen, hier nicht dargestellten, am Kur­ belgehäuse 1 befindlichen Befestigung nicht im Wege steht.In the event that lower demands are made on the exhaust gas quality, a conventional in-line injection pump can still be installed instead of the plug-in pumps, since the console 3 is not in the way of the usual fastening (not shown here ) located on the cure housing 1 .
