。 In an engine cylinder head that has an exhaust port that communicates with the exhaust port of the combustion chamber and a cooling water passage through which cooling water passes, the exhaust port is made of a triple-walled cylinder with a heat-resistant metal plate covering the entire circumference of a cylindrical insulating material. The exhaust port cylinder member passes through the cooling water passage and is fused to the cylinder head body at the inlet and outlet ends of the exhaust port and the exhaust valve guide, so that the outer periphery of the exhaust port cylinder member is cooled. An engine cylinder head characterized by facing directly into a water passage.
