Claims

[Scope of utility model registration request]

In an engine in which a cylinder head and a cylinder block superimposed on the cylinder head from below are tightened and fixed with a through bolt passing through the cylinder block, the cylinder head, the cylinder block, and the cylinder block slide inside the engine cylinder. In order to cool the engine combustion chamber formed by the moving piston separately on the cylinder head side and the cylinder block side, an upper oil circulation system that lubricates the cylinder head side and an upper oil circulation system that lubricates the cylinder block side are provided. A lower oil circulation system for lubricating is provided separately, and the lower oil circulation system is provided with an oil jacket formed around the engine cylinder and holding cooling oil, and the through bolt is inserted into the oil jacket. It is installed through the inside of the oil jacket so that it is exposed at
Further, a cover is provided to cover the outer side of the oil jacket to constitute an outer wall of the oil jacket, and the cover is provided with an oil guide projection toward an exposed portion of the through bolt inside the oil jacket. An engine cooling system characterized by:
