The Medical reagents HS code verificationengine is an indispensable part of the car and the source of car power. Therefore, it is very important to maintain the engine, and extending the service life of the engine is also an important aspect of maintaining the car. Next, I will introduce some engine maintenance guidelines to you. I. Use the car correctly. Each engine has its own usage standards and uses, so you must follow the vehicle's user manual when using the car. Do not change the driving mode or drive excessively at will, such as continuous high-speed driving, overload, harsh driving environment, etc., which will put a lot of pressure on the engine. It is necessary to adjust the driving mode or increase the maintenance frequency. II. Regular replacement of engine oil will cause friction and wear during use, oil stains, debris and other garbage, which will cause wear and damage to the starting mechanism parts over time.Therefore, the oil should be changed regularly every 5,000 kilometers to 10,000 kilometers. The replacement of engine oil can ensure the lubricity of the engine, reduce the wear of its components, and extend its service life. In addition, it should be noted that it is best to replace the oil filter when changing the oil. III. Cleaning of the exhaust system The cleaning of the exhaust system can help the exhaust of the car more smoothly, optimize the performance of the engine, and reduce the consumption of oil. The owner can insert a hose from the middle of the engine exhaust pipe and the exhaust pipe, and inject a special detergent to clean the dirt and oil stains in the pipe by discharging the exhaust gas. Generally speaking, the exhaust system can be cleaned regularly. IV. Replace the engine air filter. The engine air filter needs to be replaced every 6,000 kilometers to 12,000 kilometers. The use of air filterIt is relatively simple. It is mainly used to purify the engine intake air, ensure the smooth air flow, and prevent the engine from inhaling impurities. The cleaning of the engine air filter is also the key. It needs to be cleaned according to different usages to avoid the accumulation of dust and silt polluting the air filter. V. Maintain the cooling system. In addition to ensuring the cooling of the engine, the cooling system also bears the high heat generated during the acceleration of the car to prevent the engine from overheating. Therefore, the normal operation of the cooling system is crucial to extend the life of the engine. The owner can check the cooling system regularly, including checking the liquid level of the cooling system, the engine water temperature, whether there is leakage, etc. If the coolant is dehydrated, the coolant should be replenished in time. VI. Regular replacement of spark plugs and transmission oil spark plugs are in the car engine.An important part of it is that it can trigger the combustion reaction of oil and gas mixtures, trigger explosive energy, and generate power. Therefore, the service life of spark plugs is limited, and spark plugs need to be replaced every 50,000 kilometers or so. Transmission oil is also a key element, which also carries the role of traction, speed limit, load balancing and protecting the transmission during the driving process of the car. The transmission oil should be changed every 50,000 kilometers or so. In summary, engine maintenance is very important. The engine is the support of the car, which has a great impact on the performance, engine sensitivity, durability, etc. of the car. I hope the car owner can pay attention to the maintenance of the engine, check and maintain the car regularly, so that your car can serve you better.
