Abstract

Die vorliegende Erfindung betrifft eine Brennkraftmaschine (1) mit einem Kurbelgehäuse (2) und einer darin rotierenden Nockenwelle (3). Erfindungswesentlich ist dabei , dass ein drehfest mit der Nockenwelle (3) verbundenes Lüfterrad (5) vorgesehen ist, das ein Profil aufweist, mittels welchem bei Rotation des Lüfterrades (5) ein zumindest ölnebelreduzierter radialer Korridor (6) um das Lüfterrad (5) herum entsteht, wobei im Bereich des Korridors (6) ein Absaugstutzen (7) zur Absaugung von blowby-Gasen vorgesehen ist. Hierdurch kann insbesondere eine Absaugung von weniger stark mit Öl belastetem blowby-Gas erreicht werden.

The present invention relates to an internal combustion engine (1) with a crankcase (2) and a camshaft (3) rotating therein. Essential to the invention is that a non-rotatably connected to the camshaft (3) fan wheel (5) is provided which has a profile by means of which upon rotation of the fan wheel (5) at least a Ölnebelreduzierter radial corridor (6) around the fan (5) around arises, wherein in the region of the corridor (6) a suction nozzle (7) is provided for the extraction of blowby gases. As a result, in particular an extraction of less heavily loaded with oil blowby gas can be achieved.
