Engine cooling (the principle and international trade databasemaintenance method of the cooling system of the automobile engine) When you are driving, the work of the car engine will generate a lot of heat. Without a good cooling system, these heats may cause the engine to overheat, damage the engine, and even cause the failure of the entire vehicle. That's why the car cooling system is crucial to vehicle performance and safety.Principle of automobile engine cooling system The main function of the engine cooling system is to control the temperature of the engine and keep it within the normal working range. It transfers the heat energy between the engine radiator and the water pump to the surrounding environment through fluid circulation. When you drive a car, the engine cooling system achieves the heat dissipation of the engine through the following steps. The first step is for the pump to inject the coolant into the engine, and the liquid enters the pump from the descending pipe of the engine. The water pump uses an internal impeller to rotate and compress the coolant, and then pushes it to the engine. The second step is that the coolant absorbs heat through the engine and condenses and evaporates in the filter and water sleeve. Then go back to the engine along the pipe. This process is repeated over and over again to keep the engine temperature stable. Finally, when the coolant enters the radiator, the radiator transfers the heat energy of the coolant to the surrounding air, so that the heat energy can be discharged from the water-cooled cup.When the coolant is recycled, the engine is cooled again and maintained in a relatively constant temperature range. Maintenance method of automobile engine cooling system Maintenance of engine cooling system is very important for the long-term health and safety of automobiles. Here are several ways to keep the engine cooling system running smoothly: the first step is to regularly check whether the liquid level is normal. If the coolant level is too low, you need to add an appropriate amount of coolant. At the same time, pay attention to whether the coolant has any strange smell and color abnormalities. If there is any abnormality, the engine needs to be overhauled to eliminate the fault. The second step is to change the coolant regularly. The new coolant is clear and transparent, and its color is yellow or green. If the coolant has turned yellow or gray, or sediment is found, it may mean that the coolant needs to be replaced to avoid inhibiting the performance of the radiator.Manufacturers usually suggest how often to change the coolant, so please check the vehicle manual for more details. The third step is to regularly check the pump, radiator and other cooling system components of the engine cooling system for any damage or damage. If there is a problem, it needs to be repaired or replaced. The fourth step is to clean the radiator frequently. Insects, dirt and other debris can accumulate in the radiator, blocking its heat dissipation function. Regular cleaning can maintain the efficiency of the radiator. In summary, the engine cooling system is one of the important safety performance of automobiles. It controls the temperature of the engine through fluid circulation and heat transfer between radiators. Maintaining the smooth operation of the cooling system is the key to long-term health and safety. It is necessary to regularly check whether the liquid level and coolant need to be replaced and regularly clean the cooling system to maintain the efficiency of the radiator and check whether the radiator is damaged or damaged.
