The industry has already conducted an in-depth investigation into the situation where automobile engines waste 70% of gasoline's energy as heat. It is reported that a car traveling on a freeway has enough cooling system to dissipate enough heat for two ordinary houses! Therefore, the car cooling system is very important.
1, the choice of cooling water: The best choice for low hardness of the river, such as wells, should be boiled and then softened, it is best to use antifreeze.
2. Pay attention to the technical status of each department: If you find that the radiator is leaking, you should repair it. If you find that the pump or fan has a swing or abnormal sound, you should repair it in time. If it is found that the engine is overheated, check for lack of water in a timely manner. If there is water shortage, it should be shut down. After cooling, add cooling water. If the thermostat does not work properly and the engine operating temperature is too high or too low, repair or replace it in time.
3, the fan belt tightness check and adjustment: fan belt tightness is too small, not only affects the cooling air volume and make the engine work load increase, but also because of the skidding and accelerated belt wear. If the belt tightness is too large, it will accelerate the wear of the water pump bearing and the generator bearing. Therefore, the belt tightness should be checked during use and adjustments should be made when necessary. If it does not meet the regulations, it can be adjusted by changing the position of the generator and the adjusting arm.
4, regular cleaning scale: After the engine is used for a certain period of time, the water tank and the radiator will deposit scale and affect the heat, so it should be cleaned regularly, the cleaning method is to add enough cleaning liquid in the cooling system, soak for a period of time, start the engine After running for a certain period of time at a low or medium speed, the cleaning fluid is released while hot, and then rinsed with clean water.
However, the automobile cooling system has other important roles. The engine in the car is in the best operating state at an appropriate high temperature. If the engine gets cold, it will accelerate the wear of the components, which will make the engine less efficient and emit more pollutants. Therefore, another important role of the cooling system is to warm up the engine as quickly as possible and keep it at a constant temperature.
