とする内燃機関のシリンダヘツド。 In an internal combustion engine in which a cylinder head made of aluminum alloy is formed with two intake ports and two exhaust ports for the combustion chamber recessed in the lower surface of the cylinder head, thermal expansion of the aluminum alloy, such as a steel plate, is better. A cap body formed into a bowl shape so as to surround almost the entire combustion chamber with a material plate having a small ratio is placed in the cylinder head so that the cap body is not exposed to either the combustion chamber or the cooling water jacket. A cylinder head for an internal combustion engine, characterized by being cast in.
