Cooling method of motorcycle engine


Speaking of the cooling methods of motorcycle engines, […]

Speaking of the cooling methods of motorcycle engines, at present, they can be roughly divided into air cooling, oil cooling, water cooling and mixed cooling. Among them, air cooling is mostly used for ordinary conventional models. Many performance cars will use water cooling or mixed heat dissipation methods. To say that the difference between these several heat dissipation methods is definitely the difference in heat dissipation effect.

First of all, the advantage of air-cooled engines is that the structure is simple. The fins on the cylinder block and the cylinder head can meet the basic heat dissipation requirements of the engine. Generally, no additional auxiliary cooling accessories are needed to help, but if it is continuously driven for a long time It is very likely that the engine has a thermal decay condition because the heat dissipation method is too single.

The oil-cooled engine itself will have an additional oil-cooled radiator. Its working principle is that the conventional air cooling cannot complete the work. The engine's own lubricating oil is used to dissipate the engine heat through the radiator, so the overall heat dissipation effect is required. Better than air-cooled engines, but oil-cooled engines still need to be improved.

The water-cooled engine itself adds a liquid intervention heat dissipation method, and the overall heat dissipation effect is very obvious. Even if the engine is running at high speed for a long time, there is no need to worry about insufficient heat dissipation.

The hybrid cooling method, based on traditional air cooling, also uses oil cooling and water cooling. The combination of several methods is definitely the best cooling effect.

Generally speaking, these cooling methods are the most commonly used in motorcycle engines, of which air cooling is the basic cooling method; oil cooling is the improved cooling method; water cooling is the upgraded cooling method; and hybrid cooling method The result is optimized. Obviously, in terms of heat dissipation effects, water cooling and hybrid cooling methods are more dominant, but at the same time their overall structure is more complex and more parts are used. Therefore, in the future maintenance, it is obviously not as simple as air-cooled engines. However, the cooling effect of the air-cooled engine is not ideal.

In fact, if you buy motorcycles only for short-distance travel, air-cooled engines can fully meet the cooling needs. If you often travel long distances, water cooling and hybrid cooling methods with better heat dissipation effects are better. The best fit is the best. Everyone can figure out their own car environment and needs, and then choose the cooling method that suits them.
