The oil filter removes impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine. The function of the oil filter The main function of the engine oil is to minimize the impurities generated by friction of various parts during operation, reduce energy loss and part wear, and have the function of heat dissipation and cleaning. 2. Overflow valve: exists in the excellent* oil filter. When the engine is stopped, it can prevent the oil filter from drying out; when the engine is re-ignited, it immediately generates pressure to supply oil to lubricate the engine. When the external temperature drops to a certain value or when the oil filter exceeds the normal service life, the overflow valve will open under special pressure to allow unfiltered The oil flows directly into the engine. Filter paper: Oil filter has higher requirements for filter paper than air filter, mainly because the temperature of the oil varies from 0 to 300 degrees. Recommended replacement cycle: Cars and commercial vehicles are replaced every six months.Auto Parts—Although we often hear about oil filters, many car owners know more about it and little, so let’s talk about those things about oil filters. Installation and replacement cycle installation of the oil filter: a) Loosen the fixing screws and remove the old oil filter b) Drain or suck up the old oil c) Wipe the seal ring of the new oil filter A layer of oil d) Install Aluminum alloy machining Foundry a new oil filter and tighten the fixing screws. Technical characteristics of the oil filter Rubber sealing ring: The filter sealing ring of the excellent* oil filter is made of special rubber to ensure 100% oil leakage. Under severe temperature changes, the concentration of the oil will also change accordingly, which will affect the filtering flow of the oil. Backflow suppression valve: only available in the excellent* oil filter. Because this will allow impurities in the oil to enter the engine, the overflow valve is the key to protecting the engine in an emergency. 1. The filter paper of excellent* oil filter can filter impurities under severe temperature changes. 3. , To ensure sufficient flow
