The Importance Of Oil Filter To The Car
Even drivers who do not understand mechanical knowledge know to change the oil and oil filter regularly. But other liquids and filters also require regular maintenance. Clean oil and air also ensure the health of drivers and passengers. Therefore, in every small maintenance and major maintenance, we have to replace the oil and the oil filter.
Under normal circumstances, various parts in the engine are lubricated by oil to achieve normal operation, but the metal chips, dust, carbon deposits oxidized at high temperature and some water vapor will be continuously mixed in when the parts are running. In the oil, a long time will reduce the normal service life of the oil, and in severe cases, it may affect the normal operation of the engine.
Therefore, the role of the oil filter at this time is reflected. Simply put, the main function of the oil filter is to filter most of the impurities in the oil, keep the standby oil clean, and extend its normal service life. In addition, the oil filter should also have the performance of strong filtering capacity, low flow resistance, and long service life.
Simply put, the oil filter is mainly composed of a filter element and a shell.
Of course, there are auxiliary components such as sealing ring, support spring, bypass valve, etc. These auxiliary components are not small. For example, the role of the bypass valve is that when the filter paper fails due to excessive impurities, the oil will pass through the bypass. The valve flows into the engine for lubrication.
However, only from the appearance we see the oil filter as a whole, the filter paper, bypass valve and other parts are invisible.
Priority of oil supply is an important principle to follow when designing oil filters: that is to say, even if the filter is blocked and other extreme conditions, it is still necessary to ensure that the engine has sufficient lubricating oil supply to prevent the danger of dry grinding; This is especially important when starting a cold.
Under normal circumstances, the oil filter will be classified into the wearing parts, and in terms of replacement, basically the oil and the oil filter are replaced together. If it is used for a long time without replacing it, it may cause the loss of the function of the oil filter and eventually affect the operation of the engine.
The correct installation and regular oil filter can prevent impurities from mixing into the oil during the use of the internal combustion engine and prevent the wear of moving parts and blockage of the oil circuit. When replacing the lubricating oil, the oil filter must be replaced at the same time, so that the efficiency of the lubricating oil can be better guaranteed without affecting the quality of the lubricating oil.
It is important to buy genuine oil filters, because inferior oil filters will cause great damage to the vehicle, it will cause the car to wear, block the oil passage, and cause oil pressure disturbance.
