ABSTRACT:
A cylinder block and crankcase for a liquid-cooled internal-combustion engine is to be constructed by composite casting, a magnesium case being cast around an aluminum power unit block. The cylinder block and crankcase is conceived such that the aluminum power unit block is significantly used for the distribution of force between the cylinder head and the crankshaft bearing caps as well as for the guiding of the cooling water, in which case, the magnesium case is free of a cooling water guidance and predominantly used for the guiding of lubricating oil and, in addition, is correspondingly designed for the proportional stiffening against bending and torsion loads.
