Abstract
A light metal cylinder crankcase for combustion engines has cylinder bushings with a running layer that forms the running surface and a rough, external bonding layer for bonding the cylinder bushings to the cylinder crankcase while pouring the cylinder crankcase. At least 60% of the bonding layer relative to the jacket surface of the bonding layer is connected with the casting material of the cylinder crankcase in a material tight manner.
