Ölabscheidekammer nach dem Oberbegriff des Anspruchs 1.The invention relates to an internal combustion engine with a
Oil separation chamber according to the preamble of
Aus der DE 36 25 836 A1 ist eine Ölabscheideplatte in einer Zylinderkopfhaube für eine Brennkraftmaschine bekannt, die eine Kammer in der Haube abschließt. Diese Platte weist Entlüftungsöffnungen sowie eine Ölablaßöffnung auf.From DE 36 25 836 A1 is an oil separator plate in a cylinder head cover known for an internal combustion engine that closes a chamber in the hood. This plate has ventilation openings and an oil drain opening.
Aufgabe der Erfindung ist es, eine Ölabscheidekammer in einer Zylinderkopfhaube einer Brennkraftmaschine zu schaffen, die eine Abspaltung von Öl aus einem Ölnebel und einem gezielten Abfluß von Öl in einen Ölsammelbehälter gewährleistet.The object of the invention is an oil separation chamber in one Cylinder head cover of an internal combustion engine to create a split of oil from an oil mist and a targeted drainage of oil into one Oil collection container guaranteed.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des
Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die
Unteransprüche.This object is achieved by the characterizing features of
Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, daß ein aus dem Zylinderkurbelgehäuse aufsteigender sog. Ölnebel über Öffnungen in einer Ölabscheideplatte sich im abgeschlossenen Raum einer Zylinderkopfhaube niederschlagen kann und sich das absondernde Öl über labyrinthartig von Leitrippen begrenzten Kanälen auf der Deckelinnenfläche, Ablauf- bzw. Abtropföffnungen zugeführt wird und das Öl in einen Ölsammelbehälter abtropfen kann.The main advantages achieved with the invention are that a the so-called oil mist rising through the openings in a cylinder crankcase Oil separator plate in the closed space of a cylinder head cover can precipitate and the separating oil over labyrinth of Guide ribs limited channels on the inner surface of the cover, drain or Draining openings is supplied and the oil drip into an oil collection container can.
Zur Absonderung des Öls aus dem Ölnebel dienen die Leitrippen, welche zu diesem Zweck eine größtmögliche Länge im Haubendeckel aufweisen. Der Ablauf des Öls zu einer Seite des Motors hin wird durch die schräg eingebaute Brennkraftmaschine möglich, die quer angeordnet im Fahrzeug vorgesehen ist. Die Luft im Haubenraum wird über eine Auslaßöffnung nach außen abgelassen. The guide ribs serve to separate the oil from the oil mist have the greatest possible length in the hood cover for this purpose. Of the The drain of the oil to one side of the engine is built in through the oblique Internal combustion engine possible, which is provided transversely arranged in the vehicle. The air in the hood space is released to the outside through an outlet opening.
Die Luftöffnungen in der Ölabscheideplatte sind vorzugsweise in spritzölarmen Bereichen der Brennkraftmaschine angeordnet. Diese liegen etwa randseitig der Haube im höhergestellten Abschnitt der Platte, in bezug auf die geneigte Einbaulage des Motors gesehen.The air openings in the oil separating plate are preferably low in splash oil Arranged areas of the internal combustion engine. These are around the edge of the Hood in the raised section of the plate, with respect to the inclined one Installation position of the motor seen.
Es sind im wesentlichen zwei längsverlaufende Leitrippen sowie mehrere querverlaufende Leitrippen vorgesehen, die unter Verwendung der Wandungen der Zündkerzenrohre Kanäle bilden, die insgesamt eine derartige Ausrichtung aufweisen, daß das Öl Ablauföffnungen in der Leitrippe über lange Wege zufließen kann. Insgesamt bilden die Begrenzungen und die Leitrippen um die Zündkerzenrohre Sektoren, welche jeweils Abtropföffnungen im Rand der Haube aufweisen und somit ein gezielter Abfluß des Öls sichergestellt ist.There are essentially two longitudinal guide ribs and several transverse guide ribs are provided using the walls of the spark plug tubes form channels that together have such an orientation have that the oil drain openings in the guide rib over long distances can flow. Overall, the boundaries and the ribs form around the Spark plug tubes sectors, each draining openings in the edge of the hood have and thus a targeted drainage of the oil is ensured.
Die zwei wesentlichen in Längsrichtung verlaufenden Leitrippen erstrecken sich jeweils zu beiden Seiten der Zündkerzenrohre, wobei die tiefergelegene Leitrippe die Abtropföffnungen besitzt, so daß das sich ansammelnde Öl von der gesamten Fläche den Ablauföffnungen im Rand der Haube zuführbar ist.The two main longitudinal ribs extend on both sides of the spark plug tubes, with the lower guide rib has the drainage holes so that the accumulating oil from the whole Surface can be fed to the drain openings in the edge of the hood.
Die längs- und querverlaufenden Rippen sind über Abschnitte bogenförmig ausgeführt und laufen in die Wandungen der Zündkerzenrohre ein, so daß sich fließende Übergänge ergeben und das Öl nicht in seinem Fluß gehemmt wird.The longitudinal and transverse ribs are arcuate over sections executed and run into the walls of the spark plug tubes, so that flowing transitions result and the oil is not inhibited in its flow.
Zwischen den äußeren und den mittleren Zündkerzenrohren sind Durchflußkanäle vorgesehen, wobei zwischen den beiden mittleren Zündkerzenrohren eine querverlaufende Sammelrinne als Durchflußkanal angeordnet ist. Die Sammelrinne weist einen in der Ebene der Platte mündenden Auslauf auf. An einer Längsseite ist die Sammelrinne von einer querverlaufenden Leitrippe begrenzt, so daß abgesondertes Öl des einen Sektors gezielt ableitbar ist.There are between the outer and middle spark plug tubes Flow channels provided, being between the two middle Spark plug tubes a transverse gutter as a flow channel is arranged. The collecting trough has an opening in the plane of the plate Spout on. On one long side, the collecting trough is of a transverse one Guide rib limited, so that separate oil of the one sector can be selectively discharged is.
Die Luftöffnungen in der Ölabscheideplatte können über größere Flächenbereiche angeordnet werden, wobei diese vorzugsweise zwischen den Seitenlängswänden und einer längsverlaufenden Leitrippe angeordnet sind. The air openings in the oil separator plate can be larger Surface areas are arranged, these preferably between the Side longitudinal walls and a longitudinal guide rib are arranged.
Diese wird in vorteilhafter Weise so geneigt, daß sich mit einer querverlaufenden Leitrpippe eine trichterförmige Ölführung zu dem zwischen zwei Zündkerzenrohren angeordnetem Durchflußkanal ergibt.This is advantageously inclined so that with a transverse Leitrpippe a funnel-shaped oil guide to the between two Spark plug tubes arranged flow channel results.
