Abstract
This invention relates to a reciprocating internal combustion engine having a cylinder crankcase with a cylinder head with is designed to reduce the manufacturing and spare parts cost. A single design unified cylinder head is employed for liquid cooling and air cooling, the cylinder head having both cooling spaces for the liquid coolant and cooling fins for the cooling air. Coolant passageways in the cylinder head are connected to coolant spaces in the cylinder block portion of the cylinder crankcase by way of openings in the upper end of the cylinder block and openings in the cylinder head gasket which permit flow of coolant to the annuli in the cylinder head. In addition to the annuli, the coolant passageways in the cylinder head include a longitudinally extending header, horizontally extending web ducts extending radially inward from the annuli and vertically extending connecting conduits inclined relative to the cylinder axes interconnecting the web ducts and the header. Each connecting conduit extends through a pillar extending between the cover plate portion and the base portion of the cylinder head. The pillars are in the wind shadow of, and in a substantially parallel relationship to, injection nozzles installed in the cylinder head.
