The model of the oil filter can be viewed on the filter housing, which usually has the manufacturer's part number or refers to the vehicle maintenance manual.

The function of the oil filter:
1. During the operation of the engine, metal debris, dust, oxidized carbon deposits and colloidal deposits at high temperatures, water, etc. constantly mix with lubricating oil. The function of an oil filter is to filter out these mechanical impurities and gums, ensure the cleanliness of the lubricating oil, and extend its service life. Oil filters should have strong filtration capacity, low flow resistance, and long service life;
2. Oil filter, also known as oil filter. There are two types of oil filters: full flow and split flow. The full flow filter is connected in series between the oil pump and the main oil passage, so it can filter out all lubricating oil entering the main oil passage. The split flow cleaner is connected in parallel with the main oil channel, and only a portion of the lubricating oil sent out by the filter oil pump is filtered. Machine filters are divided into interchangeable, rotary, and centrifugal types according to their structure. The filtering materials used in machine filtration include filter paper, felt, metal mesh, non-woven fabric, etc;
3. The advantage of interchangeable machine filters is that they have low operating costs and only require regular maintenance and replacement of the filter element. The disadvantage is that there are too many sealing points, and maintenance and replacement of the filter element may miss the installation of parts, which can easily cause leaks. The characteristic of the rotary filter is that it is equipped with a check valve, a bypass valve, and only one sealing point inside. It is replaced as a whole, greatly improving the sealing performance and easy to replace. The filter element material is mostly imported filter paper, which has advantages such as high filtration efficiency, low flow resistance, and long service life.
