COOLING DEVICE FOR POWER UNIT

摘要

A device for cooling both a belt casing of an engine and the engine itself, in which both the inside and the outside of the belt casing are cooled by exterior air which is sucked in by respective fans. The air which cools the outside of the belt casing also is used to cool the rest of the engine, and then exits the engine at a side opposite the side at which the air first was sucked in. As a result, air flow through the engine does not impede rotation of the fans and hence does not hamper the cooling process.
