The car oil filter has a deep effect on the car, and there is nothing wrong with the maintenance of the car oil filter.

The role of the oil filter: Under normal circumstances, The various parts in the engine are lubricated by the oil to achieve normal work, but the metal debris, the incoming dust, the carbon deposits oxidized at high temperature and part of the water vapor generated when the parts are running will continuously mix into the oil. A long time will reduce the normal service life of the oil, and in severe cases may affect the normal operation of the engine.

Therefore, at this time, the role of the oil filter is reflected. 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. In addition, the oil filter should also have the characteristics of strong filtering ability, small flow resistance and long service life.

The oil filter is mainly composed of two parts: filter paper and shell, as well as auxiliary parts such as sealing ring, support spring and bypass valve. The role of these auxiliary components is not small. For example, the function of the bypass valve is that when the filter paper fails due to too many impurities, the oil will flow into the engine through the bypass valve for lubrication. However, only the oil filter as a whole can be seen from the appearance, and the filter paper, bypass valve and other parts are not visible.
