Abstract
Description
Die Erfindung betrifft eine Brennkraftmaschine mit einer Ölumleiteinrichtung gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to an internal combustion engine with a Ölumleiteinrichtung according to the preamble of claim 1.
Aus
der
Der Erfindung liegt die Aufgabe zugrunde, für eine Brennkraftmaschine eine verbesserte Maßnahme anzugeben, mit der eine optimierte Beruhigung des in einen Ölsammelbehälter zurückfließenden Schmieröls erzielt wird.Of the Invention is based on the object for an internal combustion engine indicate an improved measure with which an optimized Calming the lubricating oil flowing back into an oil collecting tank is achieved.
Die erfindungsgemäße Brennkraftmaschine zeichnet sich dadurch aus, dass die innerhalb des Ölsammelbehälters angeordnete Ölumleiteinrichtung derart ausgebildet ist, dass das aus dem Kurbelgehäuse in den Ölsammelbehälter zurückströmende Schmieröl zumindest teilweise gezielt in einen Bereich des Ölsammelbehälters zurückfließt, zwischen dem und einem mittleren Bereich des Ölsammelbehälters eine Trennwand vorgesehen ist. Mit der erfindungsgemäßen Ölumleiteinrichtung erfolgt eine kontrollierte Rückströmung bzw. Rückführung des in den Ölsammelbehälter zurückfließenden Schmieröls in Bereiche des Ölsammelbehälters, die vorzugsweise von einem mittleren Bereich des Ölsammelbehälters getrennt sind. Somit kann eine Entgasung und Beruhigung des zurückfließenden Ölluftgemisches, insbesondere durch die längeren Führungswege, erreicht werden, bevor das Schmieröl zu einem mittleren Bereich des Ölsammelbehälters zurückfließt.The inventive internal combustion engine is characterized characterized in that within the oil collecting container arranged Ölumleiteinrichtung is designed such that from the crankcase into the oil reservoir backflowing lubricating oil at least partially specifically in an area of the oil collection tank flows back, between that and a middle one Area of the oil collection container provided a partition is. With the Ölumleiteinrichtung invention there is a controlled backflow or return of the flowing back into the oil reservoir Lubricating oil in areas of the oil collecting tank, preferably separated from a central region of the oil collecting container are. Thus, a degassing and calming of the returning oil-air mixture, especially through the longer routes, be reached before the lubricating oil to a medium The area of the oil collection container flows back.
In einer Ausgestaltung der Erfindung wird mit Hilfe der Ölumleiteinrichtung das aus dem Kurbelgehäuse in den Ölsammelbehälter zurückströmende Schmieröl mindestens in einen Randbereich des Ölsammelbehälters umgeleitet. Somit erfolgt eine Beruhigung und eine Entgasung des zurückströmenden Ölluftgemisches, bevor diese Ölanteile in einen mittleren Bereich des Ölsammelbehälters gelangen, wo üblicherweise ein Saugschnorchel einer Ölpumpe für die Ölabsaugung positioniert ist.In An embodiment of the invention is using the Ölumleiteinrichtung that from the crankcase into the oil reservoir backflowing lubricating oil at least redirected to an edge region of the oil collection container. Thus, a calming and degassing of the back flowing Ölluftgemisches, before these oil fractions in a central region of the oil reservoir get where usually a Saugschnorchel an oil pump is positioned for the oil extraction.
Die Erfindung beruht auf dem allgemeinen Gedanken, das aus einem Kurbelraum zurückfließende Schmieröl bzw. Ölluftgemisch kontrolliert in den Ölsammelbehälter zurückzuführen, so dass eine Absaugung des Schmieröls aus einem mittleren Bereich des Ölsammelbehälters erst dann vorgenommen wird, wenn das zurückströmende Schmieröl bzw. Ölluftgemisch mit Hilfe der Ölumleiteinrichtung entschäumt und in einem Randbereich des Ölsammelbehälters gelangt ist.The Invention is based on the general idea that from a crankcase Backflowing lubricating oil or oil-air mixture controlled return to the oil sump, so that a suction of the lubricating oil from a middle Only then made the area of the oil collection container is when the back-flowing lubricating oil or oil-air mixture defoamed with the help of the oil diverter and in an edge region of the oil collection container passes is.
In einer weiteren Ausgestaltung der Erfindung sind mindestens in den Randbereichen der Ölumleiteinrichtung perforierte Abschnitte vorgesehen. Vorzugsweise ist die Ölumleiteinrichtung aus einem Blech hergestellt, welches in den Randbereichen mit mehreren Öffnungen versehen ist, wobei zur Beschleunigung des Beruhigungsvorgangs das Blech in den äußeren Bereichen in Richtung eines Ölsumpfes geneigt ist. Hierdurch erfolgt eine optimierte Rückführung sowie eine beschleunigte Beruhigung des Schmieröls bzw. des Ölluftgemisches. Darüber hinaus dienen die Öffnungen in der Ölumleiteinrichtung auch der Ventilation im Kurbelraum.In a further embodiment of the invention are at least in the Edge portions of the Ölumleiteinrichtung perforated sections intended. Preferably, the Ölumleiteinrichtung is off a sheet metal produced in the marginal areas with multiple openings is provided, to accelerate the reassurance process, the sheet in the outer areas towards an oil sump is inclined. This results in an optimized feedback and accelerated calming of the lubricating oil or of the oil-air mixture. In addition, the openings serve in the oil diverter also the ventilation in the crankcase.
Nach einer Ausgestaltung der Erfindung ist die Trennwand als eine Ölschottwand ausgebildet. Durch die Anordnung einer oder mehrerer Ölschottwände im Ölsammelbehälter werden die Ölbewegungen innerhalb des Ölsammelbehälters wirkungsvoll reduziert und die Rückführung des Schmieröls in Richtung einer Absaugungsstelle bzw. eines Saugschnorchels der Ölpumpe optimiert gestaltet. Da der Ölübertritt aus den Randbereichen in einen Ölabsaugraum über mehrere in den Ölschottwänden vorgesehenen Öffnungen erfolgt, wird mit Hilfe der Ölumleiteinrichtung das aus dem Kurbelraum zurückströmende Schmieröl in vorteilhafter Weise in den Bereich zurückgeführt, aus dem kein Schmieröl abgesaugt wird. Demnach verlängert sich die Beruhigungsdauer des Schmieröls bzw. des Ölluftgemisches und eine verbesserte Entgasung des Ölluftgemisches wird somit erzielt.To According to an embodiment of the invention, the partition wall is an oil bulkhead educated. By arranging one or more oil bulkheads in oil sump the oil movements become effectively reduced within the oil sump and the return of the lubricating oil in the direction a suction point or a Saugschnorchels the oil pump Optimized design. Since the oil transfer from the Edge areas in a Ölabsaugraum over several provided in the oil bulkheads openings takes place, with the help of the Ölumleiteinrichtung the off the crankcase flowing back lubricating oil advantageously returned to the area, from which no lubricating oil is sucked off. Therefore extended the settling time of the lubricating oil or of the oil-air mixture and an improved degassing of the oil-air mixture is thus achieved.
