Abstract:
A cylinder head (1) for an internal combustion engine has a body (2) integrating, in a single cast piece, the exhaust manifold and including a lower cooling jacket (18) and an upper cooling jacket (19). The lower cooling jacket (18) is longitudinally divided into a plurality of separate transverse chambers (180) associated to various engine cylinders, while the upper cooling jacket (19) has a portion (196) extended longitudinally over the entire development of the head (1) and communicating with separate transverse chambers (198) located on the intake side of the head (1). The exhaust conduits (9) integrated in the head form separate subgroups (16, 17) of exhaust conduits (9) merging into manifold portions (16a, 17a) superimposed and spaced apart from each other. The abovementioned lower cooling jacket (18) has a portion (20) thereof which is extended in the area of the body (2) of the head (1) which separates the superimposed portions (16a, 17a) of the abovementioned subgroups (16, 17) of exhaust conduits (9).
