Abstract
An internal combustion engine with a crankcase upper part and a crankcase lower part, wherein an oil windage tray is provided, which is flanged onto the crankcase upper part from below, projects into the crankcase lower part, forms a wall for an oil mist roller initiated by the rotation of a crankshaft, and includes at least one carpenter's plane-like slot for separating oil droplets. At least two slots are provided in the rotational direction of the crankshaft and thus in the rotational direction of the oil mist roller, wherein a return opening, through which oil mist-free gases or gases with at least a reduced oil mist content flow back, is provided in the wall of the oil windage tray after each slot, as a result of which friction is reduced.
