Claims

[Claims for Utility Model Registration] (1) In a water-cooled internal combustion engine equipped with a cylinder block having a water jacket around each cylinder, a cooling system in which cooling water flows into the water jacket and into the water jacket. A water-cooled internal combustion engine characterized in that a rectifying wall is provided near the water inlet, which extends obliquely upward toward the cylinder side downstream of the cooling water inlet, and rectifies the flow of cooling water flowing from the cooling water inlet. water jacket. (2) A water jacket for a water-cooled internal combustion engine according to claim 1, wherein the baffle wall is provided only near the cooling water inlet. (3) The scope of the utility model registration claim, wherein the baffle wall is formed so that the side wall of the cylinder bore in the water jacket is spaced from the outer wall of the water jacket, and the baffle wall extends to connect the cylinders. 1st
A water jacket for a water-cooled internal combustion engine as described in .
