What Are The Engine Cooling Methods?

The engine is cooled by air and water. Most cars use water-cooled engines, but many motorcycles still use air-cooled engines. There are many heat sinks on the cylinder block of the air-cooled engine, which can increase the contact area with the air. The following is more relevant introduction: water-cooled engine: water-cooled engine has a set of cooling system, and the water-cooled engine relies on the coolant to continuously circulate in the engine to take away heat. The coolant of water-cooled engine has two circulation paths in the engine, one is large circulation, the other is small circulation. When the engine is just started, the temperature is relatively low, and the coolant will circulate slightly. The coolant will not dissipate heat through the radiator tank during small circulation, which is conducive to rapid engine temperature rise. When the engine reaches the normal operating temperature, the coolant will circulate greatly. At this time, the coolant will pass through the radiator tank, which can keep the engine in the normal operating temperature range. The temperature of the water-cooled engine is more stable, while the temperature of the air-cooled engine is not very stable. If you drive a car with an air-cooled engine on a 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 to find a professional to replace it.
