Claims

[Scope of utility model registration request]

Cooling of the engine combustion chamber formed by the cylinder head, the cylinder block superimposed on the cylinder head, and the piston sliding 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, and the lower oil circulation system is formed around the engine cylinder. An oil jacket for retaining cooling oil is provided, and a cover covering the outer side of the oil jacket is attached to the cylinder block to form an outer wall of the oil jacket, and the cover is attached to the cylinder block. An engine cooling device characterized in that, in the upper edge mounting portion, a bubble removing gear for extracting air bubbles accumulated in the oil jacket from the oil jacket is formed by the cover and the cylinder block.
