Cooling structure of cylinder head and method for manufacturing cylinder head |
摘要 |
In a cylinder head, a cooling water passage with a circular shape (an elliptical shape) in cross section in radial direction is formed at an area (lower layer deck) closer to a combustion chamber than a water jacket in which a cooling water flows. The cooling water passage of the cylinder head is formed by casting by providing a hollow core in a mold and removing the hollow core.
