The function of oil filter is to filter most impurities in engine oil, keep engine oil clean and extend its normal service life. In addition, the oil filter should also have the characteristics of strong filtering ability, small flow resistance, long service life, etc.
The role of oil filter In general, all parts in the engine work normally through the lubrication of the engine oil, but the metal debris, dust, carbon deposits oxidized at high temperature and some water vapor generated during the operation of the parts will continue to mix into the engine oil, which will reduce the normal service life of the engine oil over a long period of time, and may affect the normal operation of the engine in serious cases.
Therefore, the role of the oil filter is reflected at this time. In brief, the function of oil filter is to filter most impurities in engine oil, keep engine oil clean and extend its normal service life. In addition, the oil filter should also have the characteristics of strong filtering ability, small flow resistance, long service life, etc.
The oil filter is mainly composed of filter paper and housing, as well as auxiliary parts such as sealing ring, support spring, bypass valve, etc. These auxiliary parts also play an important role. For example, the role of the bypass valve is that when the filter paper fails due to excessive impurities, the oil will flow into the engine through the bypass valve for lubrication. However, only the oil filter can be seen from the appearance, and the filter paper, bypass valve and other parts can not be seen.
