ABSTRACT:
A cylinder head, for an internal combustion engine, enhances engine efficiency while ensuring favorable coolant flow. The cylinder head includes a main casting body41having a hollow water jacket formed therein, to allow coolant flow therethrough. The main casting body41includes a plurality of cylindrical plug hole walls91which have plug holes90formed therein inside a head-side water jacket60. The cylinder head also includes partitions100, formed inside the head-side water jacket60, and these partitions connect the plug hole walls91together form a dividing wall, which divides the water jacket into an exhaust port section and an intake port section. Coolant entering the water jacket is divided into two substreams, which flow initially in substantially opposite directions, and which are reunited after flowing around opposite ends of the dividing wall.
