Abstract
Description
Die Erfindung betrifft eine Brennkraftmaschine mit einem Kurbelgehäuse, in dem eine Kurbelwelle drehbar gelagert ist, an der zumindest ein einen Kolben tragendes Pleuel angelenkt ist, wobei der Kolben in einem von einem Zylinderkopf unter Bildung eines Arbeitsraums abgedeckten Zylinder bewegbar ist, wobei das Kurbelgehäuse und der zumindest eine Zylinder getrennte Bauteile sind.The The invention relates to an internal combustion engine with a crankcase, in which a crankshaft is rotatably mounted, at least one a piston bearing connecting rod is articulated, wherein the piston in one covered by a cylinder head to form a working space Cylinder is movable, with the crankcase and the at least one cylinder are separate components.
Eine
derartige Brennkraftmaschine ist aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Brennkraftmaschine bereitzustellen, bei der, ausgehend von einer Luftkühlung, die Kühlleistung erhöht wird.Of the Invention has for its object to provide an internal combustion engine, in which, starting from an air cooling, the cooling capacity increases becomes.
Diese Aufgabe wird dadurch gelöst, dass auf das Kurbelgehäuse ein Zylindergehäuse aufgesetzt ist, in das ein den Zylinder bildendes Zylinderrohr eingesetzt ist, dass der zwischen dem Zylinderrohr und dem Zylindergehäuse gebildete Innenraum mit einem flüssigen Kühlmedium befüllt ist und dass das Zylindergehäuse außenseitig zumindest in Teilbereichen luftgekühlt ist. Das Zylindergehäuse umfasst dabei alle Zylinderrohre, die bevorzugt unverrippt in das Zylindergehäuse eingesetzt am oberen und des Zylindergehäuses zentriert und gehalten werden. Die solcherart gehaltenen Zylinderrohre ragen dann in bekannter Art und Weise in das Kurbelgehäuse hinein und sind gegenüber diesem abgedichtet. Die Kühlung der Zylinderrohre erfolgt durch ein flüssiges Medium, zum Beispiel Schmieröl oder Kühlwasser. Das Kühlmedium nimmt die Verbrennungswärme auf und führt diese zumindest teilweise über das luftgekühlte Zylindergehäuse ab. Zusätzlich kann in bekannter Weise das Kühlmedium von einer Kühlmittelpumpe durch einen Wärmetauscher zur weiteren direkten Abführung von aufgenommener Wärme gefördert werden.These Task is solved by the fact that the crankcase a cylinder housing is fitted, in which a cylinder forming cylinder tube is inserted, that between the cylinder tube and the cylinder housing formed interior with a liquid Cooling medium is filled and that the cylinder housing outside air-cooled at least in some areas is. The cylinder housing includes all cylinder tubes, the preferred unripped inserted into the cylinder housing Centered and held at the top and the cylinder housing become. The thus held cylindrical tubes then protrude in a known Way into the crankcase and are opposite this sealed. The cooling of the cylinder tubes takes place through a liquid medium, for example lubricating oil or cooling water. The cooling medium absorbs the heat of combustion at least in part via the air-cooled cylinder housing. additionally can in a known manner the cooling medium from a coolant pump through a heat exchanger for further direct discharge be promoted by absorbed heat.
In weiterer Ausgestaltung der Erfindung weist das Zylindergehäuse an den Außenflächen Kühlrippen auf. Dadurch wird eine weiter gesteigerte Wärmeabfuhr erreicht. In Weiterbildung der Erfindung ist ein Abgasrückführungskühler in das Zylindergehäuse integriert, der dann sowohl luftgekühlt als auch flüssigkeitsgekühlt ist. Dadurch wird bei hoher Kühlleistung ein kompakter Aufbau der Brennkraftmaschine erreicht.In further embodiment of the invention, the cylinder housing on the outer surfaces of cooling fins. Thereby a further increased heat dissipation is achieved. In training The invention is an exhaust gas recirculation cooler integrated into the cylinder housing, which is then both air cooled as is also liquid cooled. This will be added high cooling capacity a compact design of the internal combustion engine reached.
In weiterer Ausgestaltung der Erfindung weist die Brennkraftmaschine ein integriertes Kühlluftgebläse auf, das wiederum in weiterer Ausgestaltung insbesondere auch den luftgekühlten Zylinderkopf kühlt.In Further embodiment of the invention, the internal combustion engine an integrated cooling fan, which in turn in a further embodiment, in particular the air-cooled Cylinder head cools.
Der wesentliche Vorteil der erfindungsgemäß ausgebildeten Brennkraftmaschine ist es, dass, ausgehend von einer luftgekühlten Brennkraftmaschine mit Einzelzylinderrohren und aufgesetzten Einzelzylinderköpfen, die Kühlung insbesondere der Zylinderrohre in dem zu den Zylinderköpfen angrenzenden Bereich wesentlich erhöht wird. Dies wird durch die zuvor beschriebene Ausgestaltung erreicht, wobei die vorhandenen luftgekühlten Zylinderköpfe weiterverwendet werden. Lediglich das Zylindergehäuse mit den einzusetzenden Zylinderrohren, bei denen grundsätzlich auf die luftgekühlten Zylinderrohre zurückgegriffen werden kann und die Kühlrippen durch beispielsweise ein modifiziertes Fertigungsverfahren weggelassen werden, sind neu herzustellende Bauteile. Dabei ist die dermaßen ausgestaltete Brennkraftmaschine als Variante zu einer ausschließlich luftgekühlten Brennkraftmaschine zu sehen.Of the significant advantage of the invention formed Internal combustion engine is that, starting from an air-cooled Internal combustion engine with individual cylinder tubes and mounted individual cylinder heads, the cooling of the cylinder tubes in particular to the Cylinder heads adjacent area significantly increased becomes. This is achieved by the embodiment described above, the existing air-cooled cylinder heads continue to be used. Only the cylinder housing with the cylinder tubes to be used, where basically resorted to the air-cooled cylinder tubes can be and the cooling fins by, for example Modified manufacturing process can be omitted, are newly manufactured Components. This is the so-designed engine as a variant to an exclusively air-cooled Internal combustion engine to see.
