ABSTRACT:
A cylinder head for an internal combustion engine includes a plurality of cooling water passages through which cooling water for cooling the cylinder head is injected. Each of the cooling water passages is so arranged that cooling water injected therethrough is caused to unidirectionally swirl around an outer wall for a fitting hole through which a fuel injection nozzle is fitted. Thus, there is no fear that stagnation of water stream due to collision of water streams flowing around the outer wall for the fuel injection fitting hole occurs or bubbles are produced. This leads to reduction of resistance against flowing of cooling water whereby a cooling efficiency of cooling water for the cylinder head can be increased.
