Abstract:
In a method for casting a cylinder head of a piston engine in a region of cooling channels for valve seat rings, a separate core is provided for defining cooling channels, and the cooling channel core is mounted in a bottom plate of a casting mold at various points thereof. The cooling channels for the valve seat rings have a cooling channel region formed by two interconnected rings and at least one cooling fluid supply channel and at least one cooling fluid drain channel. The two rings are disposed at a distance from the valve seat rings, adjacent to them.
