Abstract

The invention relates to a bearing bridge connecting the main bearing seats of a reciprocating-piston combustion engine in the longitudinal direction of the crankshaft. To reduce the power loss caused by the oil flowing back into the crank case space striking the rotating drive parts, and the oil ageing rate, it is proposed to provide the bearing bridge between the main bearing seats with a shape which screens off the rotating drive parts of the combustion engine with respect to the crank case space.
