Abstract
In a fluid-cooled cylinder head for a series of cylinders of a multi-cylinder internal combustion engine provided with a combustion chamber for each cylinder, the cooling water chambers co-ordinated with the individual combustion chambers are separated from each other, so that individual small casting cores can be used instead of a large casting core forming all the cooling water chambers of the cylinder head. The appropriate number of small casting cores can be inserted into the mould according to the number of cylinders, so that cylinder heads for cylinder blocks with different numbers of cylinders can be manufactured, using several casting cores. The cooling water chamber for each combustion chamber is so designed that a single unipart casting core can be used, which is so shaped that the cooling water is directed against the wall of the combustion chamber and against the sparking plug dome.
