Abstract

For an internal-combustion engine in a V-arrangement, a crankcase has a parallelepiped-shaped construction with a rectangular cross-section. The base side of the crankcase corresponds approximately to the lateral projection in the area of the cylinder heads. In addition, the crankcase has at least one chamber. Preferably, several chambers are provided corresponding to the number of cylinders of the internal-combustion engine. These chambers point from the longitudinal side of the crankcase into the interior. Auxiliary assemblies, heat exchangers, filters and oil supply spaces are arranged in these chambers.
