The invention relates to the technical field of motorcycles, and discloses a motorcycle engine efficient cooling structure which comprises a crankcase, an air cylinder, an air inlet cover and an air guide cover. The lower side of the wind scooper is provided with an air outlet facing the inclined rear lower portion of the wind scooper. The air guide cover is connected with a flow guide plate at the air outlet position corresponding to the air outlet, wherein the flow guide plate is arranged in the air outlet direction of the air outlet so as to guide cooling hot air to be discharged from the inclined rear lower portion of the air outlet. According to the efficient cooling structure of the motorcycle engine, cooling hot air can be intensively and obliquely blown downwards to the rear portion of the whole motorcycle, and the cooling hot air is prevented from being blown to the legs of a driver; muddy water splashed from the front wheel platform can be better prevented from being accumulated at the air outlet to cause blockage of the air outlet; and cooling hot air exhausted from the air outlet can be blown to the crankcase under the action of the flow guide plate, heat, transmitted to the surface of the engine oil shell, of the engine oil can be taken away, and therefore the temperature of the engine oil is effectively reduced, and the thermal load of the engine is reduced.

    本发明涉及摩托车技术领域,公开了摩托车发动机高效冷却结构,包括曲轴箱、气缸、进风罩和导风罩;所述导风罩的下侧设有沿该导风罩的斜后下方朝向的出风口;所述导风罩在对应所述出风口的出风位置连接有沿所述出风口的出风方向设置以引导冷却热风从所述出风口的斜向后下方出风的导流板。本发明提供的摩托车发动机高效冷却结构可以使冷却热风集中斜向下吹向整车的后方,避免冷却热风吹向驾驶员的腿部;还能更好地避免前轮台飞溅的泥水堆积在出风口处,导致出风口堵塞;以及能够使出风口排出的冷却热风在导流板的作用下,吹向曲轴箱,可将机油传递到机油壳体表面的热量带走,从而有效降低机油温度,降低发动机的热负荷。
