ABSTRACT:
An aluminum cylinder head for an internal combustion engine has a layer of material of dispersion-hardened sintered aluminum disposed in its bottom wall which forms a combustion chamber wall, the layer comprising an insert or inserts at the sealing surface which delimits the combustion chamber and at the bridge between the intake and exhaust ports in the head for increasing the resistance of the head member to thermal shock at the bridge and for retaining for the sealing surface a high residual hardness at elevated temperatures.
