Claims

[Scope of utility model registration request]

Cooling of the engine combustion chamber formed by the cylinder head, the cylinder block that overlaps with the cylinder head from below, and the piston that slides inside the engine cylinder of the cylinder block is separated between the cylinder head side and the cylinder block side. In order to achieve this, an upper oil circulation system that lubricates the cylinder head side and a lower oil circulation system that lubricates the cylinder block side are provided separately. A cover is provided to cover the outer side of the oil jacket to form an outer wall of the oil jacket, and the cover and the cover are arranged in the oil jacket to form an outer wall of the oil jacket. An engine cooling device characterized by being provided with a partition member that partitions between an engine cylinder and allows oil to flow to the engine cylinder side.
