Abstract
Abstract A water cooled internal combustion engine which comprises a cylinder head cast integrally with both the cylinder block and the housing of an overhead camshaft, and which includes a cooling water room extending over all cylinders of the engine, a cooling water distributor channel extending in the longitudinal direction of the engine and arranged immediately above the exhaust ducts, which themselves extend transversely of the engine to an exterior cylinder head side wall, and jet bores communicating the distributor channel with the cooling water room of each cylinder.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
153 words
A water cooled internal combustion engine comprising a cylinder block, a cylinder head cast integrally with the cylinder block, an overhead camshaft housing cast integrally with the cylinder head and the cylinder block, an overhead camshaft located in said camshaft housing, intake and exhaust valves and fuel injection nozzles suspended in the cylinder head, means forming exhaust ducts which extend transversely of the engine to an exterior wall on the exhaust side of the engine, means forming a cooling water chamber extending over all cylinders of the engine, means forming a cooling water distributor channel extending in the longitudinal direction of the engine and positioned immediately above the exhaust ducts, said cooling water distributor channel communicating with the cylinder head cooling water chamber of each cylinder via means forming a bore directed towards a cylinder head wall area adjacent the intake and exhaust valves and the fuel injection nozzle of the associated cylinder.
Claim 2
Dependent Claim
