2 冷却系统的作用 冷却系统的功用是带走引擎因燃烧所产生的热量，使引擎

2 The role of the <br>cooling system The function of the cooling system is to take away the heat generated by the engine due to combustion, so that the engine is maintained within the normal operating temperature range. The engine can be divided into air-cooled engine and water-cooled engine according to the cooling method. The air-cooled engine relies on the engine to drive the fan and the airflow of the vehicle to cool the engine; the water-cooled engine relies on the circulation of cooling water in the engine to cool the engine. engine. Regardless of the cooling method adopted, the normal cooling system must ensure that the engine does not overheat in all driving environments.

2 The role of the cooling system<br> The function of the cooling system is to take away the heat generated by combustion of the engine, so that the engine remains within the normal operating temperature range. The engine can be divided into air-cooled engine and water-cooled engine according to the cooling method, and the air-cooled engine is based on the air flow of the engine to drive the fan and vehicle to cool the engine; A water-cooled engine is one that uses cooling water to circulate through the engine. Regardless of the way it is cooled, a normal cooling system must ensure that the engine does not overheat in all driving environments.
