Abstract
A crankcase for an internal-combustion engine is constructed with a crankcase top and bottom sections made of a light-metal material. Bearing points for a crankshaft and at least one cylinder space are provided. In the region of the bearing points for the crankshaft, respective parts are cast into the crankcase bottom and top sections. The cast-in parts are constructed of a material with a higher modulus of elasticity and a lower coefficient of thermal expansion than the light metal material for the crankcase bottom and top sections. The cast-in parts are constructed for each bearing point as separate, spatially mutually separated members.
