Abstract
The invention discloses a hot tube-oil-wind cooling method and device used for cooling motorcycle engine, applied to cooling single-cylinder or multicylinder motorcycle engine and universal petrol engines at 100cc-100cc discharge rates. By mushroom hot tube structure and annular inner rib tube oil way inserted in cylinder head and cover of the engine, the partial high-temperature heat of the heat engine of the engine is transmitted to peripheral fins for cooling. The partial power outputted by the engine crankshaft compulsorily cools the fins by the wind varying with the motorcycle speed in a multipoint located drying mode of steel wire soft shaft, and combines with the natural wind to finally exhaust the heat to the external environment, thus making the engine work on optimum working conditions. The device has compact structure, high reliability, beautiful model and production cost slightly higher than wind cooling and by far the lower than water cooling. It fills a gap of internal and external techniques of cooling motorcycle engine.
