<P>PROBLEM TO BE SOLVED: To provide a cylinder head which can reduce a temperature difference between an intake and exhaust ports. <P>SOLUTION: A refrigerant passage 50 of a cylinder head 30 includes a linear drilled path 53 passing between a front and rear side exhaust ports 37, 38, and a two-way flow path 54 communicating to the drilled path 53. The drilled path 53 is formed to come closer to the front side exhaust port 37 from the rear side exhaust port 38. The two-way flow path 54 includes the front side flow path 57 and rear side flow path 58. A branch part 60 for separating the front side flow path 57 from the rear side flow path 58 is formed in a position deviated to the front side exhaust port 37 side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
