Engine bar (car engine maintenance,Global trade customs valuation analysis improve car driving efficiency!) Cars are one of the important means of transportation in modern society. The engine is the "heart" of cars. Maintaining the health of the engine is crucial to the use and performance of cars. Proper engine maintenance can make your car run more smoothly, and also extend the life of the car, improve driving safety and performance of the car. Basic knowledge of engine maintenance: 1. Precautions for engine oil replacement Engine oil replacement is a very important maintenance measure, which can help the engine maintain a normal working state, but the following points need to be paid attention to when replacing the oil. First of all, replacing the oil during exercise will further remove the dirt in the engine, but it should be noted that the body should not be raised for too long to avoid affecting the engine; secondly, the oil filter is also very important. Replacing the oil filter canIn order to avoid the mixing of counterfeit inferior engine oil into the engine oil, it can also prevent suspended matter from entering the interior of the engine. Finally, it is also necessary to choose the correct specification of engine oil. Different vehicles and usage environments will have different requirements for the quality of the engine oil. It is necessary to choose an engine oil suitable for your own car model and driving environment. Two. The water temperature meter and the maintenance water temperature meter of the water tank are important indicators for detecting the water temperature of the engine. Therefore, it is very important to maintain the good working state of the water temperature meter. It is recommended to clean the water temperature meter connector regularly to avoid dirt entering and affect the indication accuracy. In addition, the water tank also needs to be maintained. With the increase of use time, a large amount of scale will be produced inside the water tank, and the scale will have a direct impact on the heat dissipation effect, so the water tank needs to be cleaned regularly. Special care should be made in the process of removing scale to avoid water leakage caused by damage to the water tank.3. The maintenance air filter of the air filter and spark plug can effectively filter the impurities in the engine air intake and prevent impurities from entering the engine. The air filter needs to be cleaned regularly to ensure the filtration effect, and it also needs to be replaced in time. With the increase of the use time, the filtration effect of the air filter will be reduced, so it is recommended to determine the replacement time according to the manufacturer's requirements or the actual situation. Spark plugs are an indispensable part of the ignition system, which will produce high-temperature and high-voltage arcs during the engine operation. Therefore, the spark plugs need to be checked and replaced regularly to ensure the normal operation of the ignition system. Four. Maintenance of batteries and generators. The battery is an important part of the automobile power system. With the accumulation of service life, the battery will gradually age. It is recommended to replace the battery according to the replacement time specified by the manufacturer to avoid abnormal situations such as difficulty in starting.The generator is another important component of the automobile power system. It needs to check its working status regularly to ensure that the generator circuit is working normally and the battery is sufficiently charged. Summary: The engine is the core component of the car, and the health of the engine is a key factor affecting the performance and life of the car. By regularly maintaining the engine, you can avoid engine problems caused by neglect of maintenance, so as to better protect your car, improve its driving efficiency and extend its service life.
