The working principle of the oil filter is simple and effective. When the engine is started, the oil pump will draw oil from the oil pan to the engine for lubrication. The oil will carry various impurities and dirt during the flow process, and the oil filter will play a role at this time. The oil passes through the filter element of the oil filter, which is provided with tiny pores. When the oil flows through, these pores can prevent dirt from entering the oil circulation system.
Oil filters usually use filter elements made of filter paper, filter screens and other materials, which can effectively filter out particles and impurities in the oil to ensure the cleanliness of the oil. With the increase of use time, the oil filter will gradually accumulate a large amount of dirt, causing the filter element to be blocked and affecting the normal flow of oil. Therefore, it is very important to change the oil filter regularly.
With the help of the oil filter, the parts in the engine can be protected from pollution and wear, and the service life can be extended. At the same time, clean oil can effectively reduce the friction and wear when the engine is running, and improve the efficiency of oil use. Therefore, regular inspection and replacement of the oil filter is one of the important measures to protect the car engine.
In short, the role of the oil filter in the car engine cannot be underestimated. It ensures the clean and smooth operation of the engine through a simple and effective working principle, and also prolongs the service life of the engine.
