Working principle

PART/011 Motorcycle water-cooled engines are cooled by flowing water surrounding the cylinder liner and cylinder head. When the temperature is high, the throttle valve will all open the water tank to start operation, and when the temperature is too high, the fan will open and cool down to the best working temperature of the engine. The working principle of the motorcycle air-cooled engine is mainly to cool parts of the engine through the air. When the vehicle is driving, the air flows into the heat sink of the cylinder head, takes away the heat inside the cylinder, and then discharge it through the exhaust pipe of the tail. From the point of view of heat dissipation, the effect of water-cooled engine is better.

Configuration difference

The cylinder of the air-cooled engine will be equipped with a heat sink, an exhaust pipe at the tail, and an air duct in the cylinder head; The main configuration of the water-cooled engine is the water pump, water tank temperature control and fan. The cooling system of the water-cooled motorcycle is more complex, and the coolant needs to be replaced regularly and the working condition of the cooling system is checked, and the maintenance cost is higher.

Appearance distinction

PART/033 Exterior styling, the overall structure of the air-cooled engine is simpler, and smaller, lighter weight, suitable for more maneuverable scenarios, such as off-road rally and mountain riding. Water-cooled engines are larger, can accommodate larger cylinders and more efficient intake and exhaust systems, improve engine power, but the overall coordination of the appearance may not be as good as air-cooled engines.

noise

Because of its simple structure, the air-cooled motorcycle has less noise and vibration effect; The cooling system of the water-cooled engine will produce a certain noise when it is working. Scene Use PART/055 If you need to travel long distance or high intensity riding state, you can choose the water cooling system to ensure continuous power output and super endurance. If the budget is limited, just a simple urban commute, a simple structure, low maintenance costs, and low noise air-cooled system can already meet the needs of most consumers.

In summary, air-cooled systems and water-cooled systems have their own advantages and disadvantages. Focus on fuel economy and low maintenance costs, it is recommended to choose air cooling; If you want to pay attention to the cooling effect, it is recommended to choose water cooling. No matter what kind of cooling system is selected, in the later maintenance, it must be maintained in accordance with the manufacturer's recommended way to ensure that the motorcycle performance remains intact.
