INTERNAL COMBUSTION ENGINE HAVING A CYLINDER HOUSING MADE FROM AN ALUMINIUM ALLOY CASTING AND HAVING CYLINDER LINERS MADE FROM A CASTING WITH A ROUGH SURFACE

摘要

In an internal combustion engine for a motor vehicle, having a cylinder housing in the form of a light metal alloy casting with working cylinder sections including cylinder liners which consist of rough-surface iron castings and which are integrally cast into the working cylinder sections with housing webs formed between adjacent liners, the cylinder housing has cooling channels formed in the housing webs between adjacent cylinder liners and the working cylinder sections of the cylinder housing for directly cooling the cylinder liners.
