Abstract: Engine cooling structure directs cooling air, introduced into a case by operation of a fan, to a cylinder block of an engine and then discharges the cooling air out of the case through an outlet port along meandering flow passages. Case cooling structure directs cooling along the inner surface of the case. Further cooling flow passage directs the air to vertically-oriented heat radiating fins so that the cooling air flows upward along the fins and then is discharged through the outlet port. Metal cooling-fan cover is supported by the lower cover via mounting members, and a resin-made cover guide is fastened to the engine together with supporting portions and interposed between the fan cover and the engine.
Abstract translation: 发动机冷却结构将通过风扇的操作引入壳体的冷却空气引导到发动机的气缸体，然后通过出口沿着弯曲的流动通道将冷却空气从壳体排出。 外壳冷却结构沿壳体的内表面引导冷却。 进一步的冷却流路将空气引导到垂直取向的散热片，使得冷却空气沿翅片向上流动，然后通过出口排出。 金属冷却风扇盖由下盖通过安装构件支撑，树脂制的盖引导件与支撑部分一起固定在发动机上，并插在风扇盖和发动机之间。
