BACKGROUND OF THE INVENTION A cylinder head of an internal combustion engine is provided with a water jacket, through which cooling water flows to cool the cylinder head. In the case of a compact cylinder head, sufficient water jacket space between the valves cannot be secured, making it difficult to cool the valves and valve seats properly, which can cause uneven wear and seizure, so careful consideration must be given to the cooling structure. must be done. In some diesel engines, which are particularly subjected to thermal conditions, a passage is provided that runs from the outer wall of the cylinder head to the water jacket and penetrates between the valves in order to compensate for the lack of cooling water passages. It cannot be said that the effect is sufficient.
