ABSTRACT:
A cylinder head, for a water cooled internal combustion engine, which reduces the thermal stresses. The gas-changing channels and the oil-return channels are located on one side. A main water overflow, in conjunction with an oppositely located auxiliary water overflow, makes possible a precise or directed flow along the valve land portion and around the turbulence chamber or the injection nozzle channel, whereby the flow is kept along the cylinder head bottom by a roof-shaped wall on the side remote from the cylinder block. The strength of the cylinder head is increased, and the oil removal is improved, by associating an oil-return channel with each cylinder. Specially shaped cylinder head screw channels increase the compression or pressure against the combustion chamber walls and effect a more uniform pressure distribution. A more favorable sealing behavior is attained by compensation or expansion curvatures in the cylinder head cover plate.
