Abstract
The description relates to a crankcase made of light metal for an internal combustion engine with a parting plane (4) running through the crankshaft axis between a case upper part and a case bottom part, whose bearing walls (2), which connect the case outer walls (1), are provided with inserts (3) made of an iron material, in which the bearing shells of the crankshaft bearing and the bearing bolts (7) provided on both sides of the bearing shells are borne. To achieve favorable construction features it is suggested that the bearing walls (2) forming a continuous light metal bridge between the case outer walls (1) accommodate the inserts (3) that are lower than the bearing walls (2) in recesses (8) starting from the parting plane (4) and are provided, in the area of the bearing bolts (7), with through holes (9) for the bolt heads (10).
