摘要

Manufacturing at least one cylinder with cylinder crankcase for a reciprocating piston engine by casting, comprises producing a water jacket, which at least partially surrounds the cylinder for cooling, and forming at least one water distribution channel with longitudinal extension direction, adjacent to the water jacket, using at least one expendable core (10), which is at least partially cast in a casting material. An independent claim is also included for cylinder crankcase comprising at least one cylinder and a water jacket formed by the expendable core over molding at least in some regions with a casting material, where the water distribution channel is formed by the expendable core over molding at least in some regions with the casting material.
