To secure detection accuracy of a temperature sensor in a general purpose engine.SOLUTION: A general purpose engine includes: an engine body 21; an output shaft 22 which outputs rotational force of the engine body; a cooling fan 40 which is rotationally driven by the output shaft; a cooling cover 50 which is fixed to the engine body so as to define a cooling air passage CP for guiding cooling air generated by the cooling fan along an outer wall 21e of the engine body; and a temperature sensor 60 which is fixed to the engine body in an area away from the cooling air passage CP. The structure can measure a temperature of the engine body with high accuracy and perform electronic control of fuel injection with high accuracy.SELECTED DRAWING: Figure 2

    【課題】汎用エンジンにおいて、温度センサの検出精度を確保し得るようにする。【解決手段】汎用エンジンにおいて、エンジン本体21、エンジン本体の回転力を出力する出力軸22、出力軸により回転駆動される冷却ファン40、冷却ファンにより生成される冷却風をエンジン本体の外壁21eに沿うように案内する冷却風通路CPを画定するべくエンジン本体に固定された冷却用カバー50、冷却風通路CPから外れた領域においてエンジン本体に固定された温度センサ60を備える。これによれば、エンジン本体の温度を高精度に測定でき、燃料噴射の電子制御を高精度に行うことができる。【選択図】図2
