The filters are all on the engine, most of them are in the middle and lower part of the engine, and a few are on the top:
1. The oil filter, also known as the oil grid, is used to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine;
2. The oil filter is divided into 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 all the lubricating oil entering the main oil passage;
3. The split-flow cleaner is connected in parallel with the main oil passage, and only filters part of the lubricating oil sent by the oil pump;

The function of the oil grid is to:
1. Under normal circumstances, the various parts in the engine are lubricated by oil to achieve normal work. However, metal chips, incoming dust, carbon deposits oxidized at high temperatures, and part of the water vapor generated during the operation of the components will be continuously mixed into the oil. Over time, the service life of the oil will be reduced, and in severe cases, it may affect the normal operation of the engine;
2. Therefore, the role of the oil filter is reflected at this time. Simply put, the function of the oil filter is to filter most of the impurities in the oil, keep the oil clean and prolong its normal service life;
3. In addition, the oil filter should also have the characteristics of strong filtering ability, small flow resistance and long service life.
