Abstract (en)
[origin: US4781158A] An air-cooled block cylinder head adapted for mounting on an open-deck cylinder casing of an internal combustion engine. In order to maintain a tight seal of the cylinder head to the cylinder casing, the combustion chamber floor of the cylinder head is designed to be deflected in a manner that does not adversely affect the sealing of the cylinder head to the cylinder casing. This is achieved by designing the cooling chamber side of the cylinder head floor with a gradually changing floor wall thickness in the area directly above the cylinder combustion chamber. In the preferred designs, the combustion chamber floor is designed to be concave or convex. The cylinder head also includes features for effectively cooling the combustion chamber floor and for isolating the exhaust conduit.
