As a part of internal combustion engine, the oil filter plays a very important role in the lubrication system. It can filter out the impurities such as metal scraps, carbon particles and the gelatinized particles gradually produced by the oil produced in the combustion process of the engine. These impurities will accelerate the wear of moving parts, easy to cause lubricating oil road blockage, oil filter to ensure the normal operation of the internal combustion engine, the service life of the internal combustion engine is greatly improved, can also extend the service life of other parts.
What you need to know about changing your oil filter
Compared to paper filters, iron filter elements can be cleaned and recycled, iron is more environmentally friendly, and iron suction is faster and better. Compression resistance is relatively good. When disconnecting the filter element, We will find that there is a spring in it.
This is actually a pressure valve to press the filter element inside the oil filter, if not, the filter element will not play a practical role. If the oil pump is not replaced when the filter element is maintained for a long time, it will overcome the resistance of the spring to lubricate the engine directly, and it will not play the role of filtration. If the pressure valve is opened after the filter is blocked, the oil will go directly to the main oil channel without passing through the filter element and play the role of the bypass valve。
