First Claim
1. A cylinder head of an internal combustion engine comprising:
- a pair of intake ports communicating with a combustion chamber; and
an inter-ports flow path for flowing cooling water formed between port walls on opposing sides of the pair of the intake ports, wherein,wall thickness of the port walls on the opposing sides is thinner than wall thickness of the port walls on reversing side of the pair of the intake ports,the opposing side is the side on which the port walls of the pair of the intake ports face each other, andthe reversing side is the side opposite to the opposing side and is the side on which the port walls of the pair of the intake ports face away from each other.

Abstract
In a cylinder head according to an example of the present disclosure, a pair of intake ports communicating with the common combustion chamber are formed so that the wall thickness of the port walls on opposing sides is relatively small and the wall thickness of the port walls on reversing sides is relatively large. Herein, the opposing side is the side on which the port walls of the pair of the intake ports face each other. The reversing side is the side opposite to the opposing side. That is, the reversing side is the side on which the port walls of the pair of the intake ports face away from each other. An inter-ports flow path for flowing the cooling water is formed between the port walls on the opposing sides of the pair of the intake ports.
