Abstract
In a water-cooled, multi-cylinder internal combustion engine, which comprises a cylinder block, a cylinder head, and a cooling jacket, all cast in one piece and wherein the cylinder head comprises, for each cylinder of the cylinder block and on one longitudinal side thereof, an intake and exhaust duct as well as valve guide sockets and on the other longitudinal side a mounting socket for an injection nozzle or sparking plug, forming a connection between the end wall of the cylinder and the cooling jacket, at least one fin is provided on the side where the mounting socket is arranged to make an additional connection between the end wall of the cylinder and the cooling jacket. This arrangement compensates for the differential section modulus between the two longitudinal sides of the cylinder head regarded as a bending section, that is to say, the neutral axis of the cylinder head is shifted, at least approximately, back into the plane which contains the cylinder axes. This achieves an even distribution of combustion forces from the end wall of the cylinder to the cooling jacket and by comparison with the conventional arrangement reduces noise emission from the exposed longitudinal si…
