[0002] The oil filter is responsible for filtering the media in the lubrication system. During engine operation, metal debris, dust, carbon deposits oxidized at high temperatures, colloidal sediments, and water continuously mix into the lubricating oil. The oil filter is located in the engine lubrication system, upstream of the oil pump and downstream of the various engine components that require lubrication. Its function is to filter out mechanical impurities and colloids from the oil, ensuring the cleanliness of the lubricant and extending the service life of these components. An oil filter should have strong filtering capacity, low flow resistance, and a long service life.

[0003] When the engine is running, the friction between the internal steel components such as the piston rings, crankshaft, and camshaft will produce some tiny metal debris. These debris circulate in the engine with the engine oil and re-enter the friction parts of the engine, causing secondary wear on the engine components. Utility Model Content
