What are the forms of engine water cooling? What are their characteristics?
The cooling methods of the engine include air cooling and water cooling.
Most cars use water-cooled engines, but many motorcycles still use air-cooled engines. There are many fins on the cylinder block of air-cooled engine, which can increase the contact area with air.
Here are more relevant introductions:
Water-cooled engine: water-cooled engine has a set of cooling system. Water-cooled engine keeps circulating heat in the engine by means of coolant. The coolant of the water-cooled engine has two circulation paths in the engine, one is a large cycle and the other is a small cycle. When the engine is just started, the temperature is relatively low, and the coolant will circulate for a small time. The coolant will not pass through the radiator tank to dissipate heat during small circulation, which is conducive to rapid engine temperature rise. When the engine reaches the normal operating temperature, the coolant will undergo a large circulation. At this time, the coolant will pass through the radiator tank, which can keep the engine at the normal operating temperature range. The temperature of water-cooled engine is more stable. The temperature of air-cooled engine is not very stable. If you drive a car with air-cooled engine on the road that is often congested, the engine is very easy to overheat. The coolant of the water-cooled engine needs to be replaced regularly. If it is not replaced for a long time, the boiling point of the coolant will drop and the freezing point will rise, which will affect the normal operation of the engine. When replacing the coolant, be sure to go to a professional organization and find a professional to replace it.
