Abstract
The oilpan of a low-noise crankcase is bolted to the downwardly extending ankcase sidewalls and has omega-shaped crosspieces extending transversely to the oilpan sidewalls and to the sidewalls of the crankcase, and the crosspieces are in alignment with the main bearing walls of the crankcase. The crosspieces form part of the oilpan and are connected to its sidewalls in such a manner that forces are propagated, the sidewalls being reinforced as compared to the bottom of the oilpan which is not reinforced. The oilpan is bolted to the crankcase by additional bolts located in pockets in the crosspieces on both sides of the cylinder axes, and are attached to the crankcase as far away from the outer walls thereof as possible.
