Abstract (en)
[origin: EP0339453A2] A cast cylinder head for an internal combustion engine is described which has at least one recess each for an inlet and an outlet duct, the recesses each having a contour which can be produced by drawing cores. In order to obtain the best possible flow conditions, despite the restrictions imposed by the drawing cores, particularly when designing the inlet ducts, it is proposed that a tube-like insert (8) forming a duct shape favourable to the flow be held at least in the recess (7) for the inlet duct (6). This insert may be formed by means of a compression-moulded sheet metal hollow body. <IMAGE>
