Abstract:
A crankcase is provided for an internal combustion engine with at least one coated cylinder bore, which has a chamfer on a separating surface facing a cylinder head. A countersink is arranged on the chamfer. The geometry allows an additional grinding process on a separating surface facing a cylinder head to be omitted.
