Abstract: An air-cooled engine capable of enhancing detection precision of a temperature sensor includes a crankcase, a crankshaft, a fan case, and an engine cooling fan. The installation direction of the crankshaft defines the front and rear direction. The fan case is provided in a front part of the crankcase, and the engine cooling fan is accommodated in the fan case. The air-cooled engine includes a cooling wind passage, a wind passage terminal end wall, an oil splashing device, and a temperature sensor. The wind passage terminal end wall is provided in a rear end of the cooling wind passage, the oil splashing device is provided on the rear side of the wind passage terminal end wall and formed to splash engine oil in the crankcase onto the wind passage terminal end wall, and the temperature sensor is attached to a front part of the wind passage terminal end wall.
