According to the invention, the cylinder head (10) is formed of at least two mutually coupled hollow portions (21, 22), at least one of said portions (22) being constructed of a material of low thermal conductivity. The two portions (21, 22) of the cylinder head (10) are physically separated from each other. One of them (22) comprises at least one cavity acting as the intake cavity, the other portion having at least One cavity acting as the discharge cavity. <IMAGE>
