What is the car three filter? What is the role of the automotive three filters? [汽车基本知识]

car'Three filters' meansair filter,Oil filterWith gasolineFilter. The "three filters" filter air, oil and gasoline on the car engine, thereby protecting the engine and improving the working efficiency of the engine. The'three filters' are cleaned and maintained in a timely manner, which can make full use of engine performance, reduce engine failure rate, and help prolong the service life of the engine. One, car air filter There is a lot of dust suspended in the air, and the main component is silica, which is a harder substance than metal. Installing an air filter can reduce the number of cylinders,pistonwithPiston ringWear and tear of parts. If the car is not installed, the cylinder wear will increase by 7 times, the piston wear will increase by 3 times, and the piston ring wear will increase by 8 times.So modern car engines are all inCarburetor(Or the air intake control device of an EFI engine) an air filter is installed at the closing part. At present, most automobile engines use a dry air filter with a paper filter element that is small in quality, low in cost, easy to replace, and high in filtration efficiency. Beijing 51 Auto Service Center reminds you: Generally, it is cleaned every 5000 kilometers. When cleaning, you should take out the filter element and gently tap the end surface, and blow from the inside out with compressed air to remove the dust on the core. Do not use gasoline or water to wash it. The air filter must be replaced every 10,000 kilometers. 2. Automobile oil filter During the use of the internal combustion engine, mechanical impurities such as dust, metal wear debris, and carbon cleaner will continue to be mixed into the engine oil. At the same time, the oxidation of air and combustion exhaust gas on the engine oil will also cause the engine oil to gradually produce gums. The mixture of mechanical impurities and gums will also reduce Oil sludge will be formed, which will not only accelerate the wear of moving parts, but also easily block the oil circuit. To ensure the cleanliness of the engine oil, the engine is equipped with an organic oil filter in the lubrication system. Beijing 51 Automobile Service Center: At present, most car engines use spin-on oil filters. This kind of filter is a disposable filter that is not removable and washable. When replacedlubricating oilThe oil filter must be replaced at the same time, otherwise it will affect the quality of the lubricating oil. The oil and oil filter replacement cycle is generally 5000 kilometers. Three, gasoline filter In the process of gasoline storage, transportation and refilling, it is inevitable that some impurities and moisture will be mixed in. These impurities will be brought into the fuel supply system and the engine cylinder along with the fuel, and the cylinder will accelerate the wear. Before gasoline enters the gasoline pump, it must be filtered to ensure the normal operation of the gasoline supply system. Beijing 51 Automobile Service Center reminds you: At present, most engines are equipped with disposable non-removable paper filter gasoline filters, and the replacement cycle is generally 10,000 kilometers. The filter has an arrow mark on the oil inlet and outlet ports. Do not install it backwards when replacing it. Beijing 51 Auto Service Center specially recommends: The protection of the car's "three filters" must be maintained by professional maintenance personnel, and it can complete all kinds of auto repair and maintenance with professional technical and standardized services.
