Abstract
An oil deflector for an internal combustion engine has first and second oil-deflecting plates between a crankshaft and an oil pan. In order to configure the overall space, and in particular the overall height, of an oil-deflecting device so that it is as small as possible, it is proposed to arrange the oil-deflecting plates such that they overlap at a distance apart over the length of the crankcase. The longitudinal edge of the second oil-deflecting plate forms a main oil scraper edge. Strip-shaped ribs are arranged between the oil-deflecting plates, in their overlapping region, for the purpose of guiding oil in the direction of a suction point of the oil pan. The first oil-deflecting plate has apertures in the region of the width of a respective crank assembly assigned thereto. These apertures serve as secondary oil scraper edges.
