Abstract
In a crankcase of an internal combustion engine with lower and upper crankcase parts joined together along a separation plane extending through the axis of crankshaft bearings mounted in the transverse walls of the crankcase, the upper crankcase part has side walls with cut-outs formed therein and a cup-shaped member is disposed within the crank chamber formed between the transverse walls of the crankcase to cover the cut-outs. The cup-shaped member has an opening adjacent the respective cylinder of a cylinder block extending from the upper crankcase for accommodating a connecting rod extending between the crankshaft and a piston in the respective cylinder of the cylinder block.
