却装置。 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 that allows cooling oil to flow in from one side of the engine cylinder and flows out from the other side of the engine cylinder, and an end of the oil jacket part on the oil outflow side of the oil jacket. In order to discharge air bubbles accumulated in the cylinder block, an air bubble discharge passage is interposed between the upper part at the end of the oil jacket part on the oil outflow side and the part communicating with the oil pan connected to the lower part of the cylinder block. An engine cooling system characterized by:
