To provide a water-cooled engine such that deposits such as glass, straw, etc., caught on a wind suction face of a radiator can be efficiently removed.SOLUTION: A water-cooled engine comprises wind suction faces on a side where a radiator fan is present and the opposite side as both faces of a radiator, and is configured to suck normal-rotation wind from the wind suction face to the radiator with sucking force of the radiator fan which rotates normally under normal rotation control 3a over a motor, and also jet reverse wind from the wind suction faces of the radiator with feed force of the radiator fan which reverses under reversing controls 3b, 3d over the motor. On receiving a reversing command signal 4a, an electronic control device performs the reversing controls 3b, 3d a plurality of times, and performs a rotation stop control 3c between the successive reversing controls 3b, 3d.SELECTED DRAWING: Figure 1
【課題】ラジエータの吸風面に詰まった草や藁等の堆積物を効率的に除去できる水冷エンジンを提供する。【解決手段】ラジエータの両面のうち、ラジエータファンのある側と反対側の面を吸風面とし、モータの正回転制御3aで正回転するラジエータファンの吸引力により、吸風面からラジエータに正回転風を吸入すると共に、モータの逆回転制御3b・3dで逆回転するラジエータファンの圧送力により、ラジエータの吸風面から逆回転風を噴出させるように構成され、逆回転指令信号4a)受信に基づいて、電子制御装置が複数回の逆回転制御3b・3dを行うと共に、相前後する逆回転制御3b・3dの間に挟まれた回転停止制御3cを行うように構成されている。【選択図】 図1
