The importance of oil filters

When the engine is working, metal wear debris generated by friction, impurities in the air, oil oxides, etc. will be mixed into the engine oil, causing the impurities in the engine oil to gradually increase. The oil filter can filter impurities and oil stains in the oil, provide clean and reliable lubricating oil for the engine, reduce wear and extend the life of the engine.

Key features of oil filter

· High shell strength and pressure and corrosion resistance: The oil filter is located in the engine compartment, which belongs to the high temperature, high humidity and high vibration area. It has high requirements for the strength of the shell and the pressure and corrosion resistance.

· Tightness: The principle and use of the oil filter determine its high tightness requirements. A good machine filter usually uses high-performance sealing materials and reliable connection technology to ensure 100% sealing of the product. The rubber seal ring is softer and more elastic, which can better ensure the sealing performance

· Bypass and non-return function: to ensure that the required oil pressure can be established as soon as possible when the engine is restarted to avoid dry friction. A good oil filter has a check valve design to block the return of the oil after the car is turned off, so as to avoid the reduction of the oil pressure in the entire lubrication system due to the return.

· Filtering effect: The function of the oil filter is to purify the oil, and its core is the filtering effect of the filter element. Good machine filter, using high-efficiency filter material and excellent paper folding technology, the filter element is stable, the paper folding gap is even, the effective filtering area is large, and the filtering precision is high.
