WATER-COOLED CYLINDER HEAD FOR A MULTI-CYLINDER INTERNAL COMBUSTION ENGINE

摘要

A water-cooled cylinder head for a multicylinder internal-combustion engine, has a cylinder head housing which has charge cycle ducts, passage bores for receiving cylinder head screws, valve stem guides for inlet and outlet valves controlling the charge cycle ducts, and part-spherical combustion chamber caps which are bounded by a water cooling jacket on a side facing away from the combustion chamber. One spark plug dome respectively has an opening leading to the combustion chamber of the respective cylinder. For reinforcing the cylinder head housing and/or for supporting the part-spherical combustion chamber caps, a rib structure is integrated in the cylinder head housing.
