列多気筒空冷エンジンの冷却装置。[Claims for Utility Model Registration] A plurality of cylinders 3 are arranged in series within the cylinder block 2, and a coolant jacket 13 is formed within the head block 4 fixed to the upper surface of the cylinder block 2. Part of the lubricating oil is supplied to oil-cool the head block 4, and the cylinder block 2 and head block 4 are air-cooled with cooling air from a cooling fan 7 disposed on a rotating shaft 6 protruding from one side of the cylinder block 2. In the oil-cooled in-line multi-cylinder air-cooled engine configured as above, independent head blocks 4 are fixed to the upper surface of the cylinder block 2 in correspondence with each cylinder 3, and an auxiliary combustion chamber 1 is formed in each head block 4.
The outer periphery of the head block 2 is surrounded by a coolant jacket 13, and an oil passage 14 for supplying part of the engine lubricating oil to the coolant jacket 13 is connected to each head block 4.
It is formed between the intake valve 15 and the exhaust valve 16 in the valve, and is configured to individually supply cooling lubricating oil to each coolant jacket 13, and a cooling oil lead-out path from each coolant jacket 13. 17 are merged and connected to an oil cooler 18, and an oil return path 21 from the oil cooler 18 is formed in one headblock 4.
