Whether it is minor or major maintenance, the auto oil filter needs to be replaced every time the car is maintained. As we all know, the main function of the filter is to filter impurities, and the auto oil filter is no exception. A high-quality oil filter needs to use high-quality multi-layer gradient filter materials to filter out debris, oil colloids and other impurities generated during the operation of the vehicle; Structurally, the oil filter is mainly composed of outer sealing ring, gland parts, check valve disc, filter parts, compression spring, and outer shell. Of course, small components such as fixed plate, bypass valve part, outlet, oil check valve and other auxiliary components are important. For example, in terms of the bypass valve, when the car is cold started or the temperature is low, which causes the oil viscosity to be too high, it should be opened in time to ensure that the oil enters the lubrication system through the filter in time and the car gets lubricated in time. At the same time, from the appearance we can just see the whole auto oil filter, and the filter paper, bypass valve and other parts are invisible.
The function of the auto oil filter is to filter the impurities generated during the operation of the vehicle. Under normal circumstances, various parts in the engine are lubricated by oil to achieve normal work, but the metal chips, dust, carbon deposits that are oxidized at high temperature and some water vapor will be continuously mixed in the oil when the parts are running. For a long time it will reduce the normal service life of the oil, and in severe cases, it may affect the normal operation of the engine. At this time, the role of the auto oil filter is reflected: The auto oil filter filters most of the impurities in the oil while keeping the oil clean continuously, thereby prolonging the normal service life of the engine. In terms of performance, auto oil filters should also have comprehensive performances such as strong filtering capacity, low circulation resistance, and long service life. Generally, the oil and the auto oil filter are regularly replaced together. If they are not replaced for a long time, it may cause the function of the auto oil filter to be lost, and ultimately affect the operation of the engine.
