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 is provided to allow cooling oil to flow in from one side of the engine cylinder and to flow out from the other side of the engine cylinder, and to form an outer wall of the oil jacket. A cover is provided to cover the outer part of the
The cover covering the outer side of the oil jacket part on the oil spill side of the oil jacket is formed with an oil gear gallery that receives the oil spilled from the oil jacket part on the oil spill side. An engine cooling device characterized in that an oil discharge passage separate from the cylinder block is interposed between the oil pan and the oil pan connected to the lower part.
