Summary:To secure detection accuracy of a temperature sensor in a general purpose engine. A general purpose engine includes an engine main body (21), an output shaft (22) that outputs a rotation force of the engine main body, a cooling fan (40) that is rotated and driven by the output shaft, a cooling cover (50) that is fixed to the engine main body to define a cooling air passage (CP) which guides cooling air generated by the cooling fan along an exterior wall (21e) of the engine main body, and a temperature sensor (60) that is fixed to the engine main body in a region away from the cooling air passage (CP). Accordingly, it is possible to measure a temperature of the engine main body with high accuracy and perform electronic control of fuel injection with high accuracy.
