Abstract: The crankshaft bearing of a multicylinder internal combustion engine has an upper and a lower bearing part, as well as upper and lower bearing brackets with bearing bores connected therewith, in which brackets the main bearing pins of a crankshaft are mounted. The main bearing pins of the crankshaft are supplied with lubricant through oil grooves in the bearing bores. In order to guide the oil escaping from the bearing locations, which oil is flung-off by the rotating crankshaft cheeks, oil grooves are provided on the lateral surfaces of the bearing brackets. The groves are open on their radial interiors and drain downward in the installed position. This prevents severe foaming of the oil, since the oil flung-off the crankshaft can be captured directly and guided. The residence time of the oil in the crank chamber is reduced so that the oil flows more rapidly back into the oil pan and churning losses are reduced.
