Abstract (en)
[origin: WO2005093243A1] The invention relates to a water-cooled cylinder head for a multi-cylinder internal combustion engine, comprising a cylinder head housing (10) provided with gas exchange valves, boreholes (48, 49, 50) for receiving cylinder head screws, valve shaft guides (24 to 46) for the inlet and outlet valves controlling the gas exchange channels, combustion chamber spherical caps (64, 66, 68) that are defined by a water jacket (70, 72, 74) on the side opposing the combustion chamber, and respectively one spark plug dome having an opening (18, 20, 22) leading to the combustion chamber of the respective cylinder. According to the invention, in order to rigidify the cylinder head housing (10) and/or to support the combustion chamber spherical caps (64, 66, 68), a rib structure (76, 80, 82) is integrated into the cylinder head housing.
