The oil filter model can be checked on the filter housing, and basically has the manufacturer's part number, or refer to the vehicle maintenance manual.
The role of oil filter:
1. During the working process of the engine, metal wear debris, dust, carbon deposits oxidized at high temperature and colloidal deposits, water, etc. are continuously mixed into the lubricating oil. The function of the oil filter is to filter out these mechanical impurities and gums, to keep the lubricating oil clean, and to extend its service life. The oil filter should have strong filtering capacity, low circulation resistance, and long service life;
2. Oil filter, also known as oil grid. The oil filter is divided into full-flow type and split-flow type. The full-flow filter is connected in series between the oil pump and the main oil passage, so it can filter all the lubricating oil that enters the main oil passage. The split-flow cleaner is connected in parallel with the main oil passage to filter only part of the lubricating oil sent by the oil pump. According to the structure, the machine filter can be divided into replaceable type, spin-on type and centrifugal type. The filter materials used in the machine filter include filter paper, felt, metal mesh, non-woven fabric, etc.;
3. The advantage of the replaceable filter is its low cost, and it only needs regular maintenance and replacement of the filter element. The disadvantage is that there are too many sealing points, maintenance and replacement of the filter element may miss the installation of parts, which is easy to cause loopholes. The spin-on filter is characterized by a check valve, a bypass valve, and only one sealing point. The integral replacement greatly improves the sealing performance and is easy to replace. The filter element material is mostly imported filter paper, which has high filtration efficiency. , Small flow resistance, long life and other advantages.
