Abstract
A cylinder head for an internal combustion engine has a body integrating in a single cast piece, the exhaust manifold. The exhaust conduits form separate subgroups merging into manifold portions superimposed and spaced apart from each other. A lower cooling jacket, an upper cooling jacket and an intermediate cooling jacket are formed in the head. The lower cooling jacket is longitudinally divided into a plurality of separate transverse chambers, while the upper cooling jacket has a portion extended longitudinally over the entire development of the head. The lower cooling jacket has a portion extending in the area of the body which separates the superimposed portions of the subgroups of exhaust conduits. The intermediate jacket forms a main outlet at an end of the head. The upper jacket has a first portion at the center of the head and a second portion forming an auxiliary circuit adjacent to said main outlet.
