Abstract

An air/oil-cooled internal combustion engine capable of increasing accuracy in detection of the temperature of the air/oil-cooled internal combustion engine by a temperature sensor and carrying out the warm-up operation after the start-up of the air/oil-cooled internal combustion engine favorably. The air/oil-cooled internal combustion engine includes cooling fins that are provided on the circumferences of a cylinder block and a cylinder head; and a cooling passage that is provided in a combustion chamber upper wall covering a combustion chamber of the cylinder head and is used for cooling the combustion chamber upper wall with lubrication oil. The air/oil-cooled internal combustion engine has a temperature sensor configured to detect the temperature of the air/oil-cooled internal combustion engine by detecting the temperature of oil. The temperature sensor faces a cooling oil outlet portion of the cooling passage.
