Abstract
The invention relates to a cylinder head (1) for an internal combustion engine having at least one cylinder, having at least one valve seat ring (3) for a lifting valve, wherein the valve seat ring (3) is surrounded by an annular cooling channel (4) for a coolant which is formed at least partially into the cylinder head (1), wherein the cooling channel (4) surrounds the valve seat ring at least partially and extends between at least one inlet (5, 15, 25) and at least one outlet (6). In order to reduce the valve wear, it is provided that, as viewed in a section perpendicularly with respect to the axis (3a) of the valve seat ring (3), the cooling channel (4) has at least one preferably substantially crescent-shaped bulge (10) in the region of the inlet (5, 55, 25) and/or the outlet (6).
