The oil filter, also known as machine filter, or oil grid, is located in the engine lubrication system. The upstream of the filter is the oil pump, and the downstream is all parts of the engine that need lubrication. The oil filter can be divided into full flow type and split flow type. The full flow filter is connected in series between the mobile phone oil pump and the main oil passage, so it can filter all the lubricating oil entering the main oil passage. The split flow cleaner is connected in parallel with the main oil passage, and only part of the lubricating oil sent by the oil pump is filtered.

Function of oil filter

The machine filter filters out the harmful impurities in the oil from the oil pan, and supplies the crankshaft, connecting rod, camshaft, supercharger, piston ring and other moving pairs with clean oil to lubricate, cool and clean, so as to prolong the service life of these parts. Simply put, the function of the oil filter is to filter the oil, make the oil entering the engine cleaner, and prevent impurities from entering the engine and damaging precision parts.

Operating principle of oil filter

During the working process of the engine, metal wear debris, dust, carbon deposit and colloidal sediment oxidized at high temperature, water, etc. are constantly mixed with the lubricating oil. The function of the oil filter is to filter out these mechanical impurities and colloids, ensure the cleanness of the lubricating oil and prolong its service life. The engine oil filter shall have strong filtering capacity, small flow resistance and long service life. In general, several filters with different filtration capacity - collector filter, coarse filter and fine filter are installed in the lubrication system, which are connected in parallel or Changlian in the main oil passage respectively. The filter connected in series with the main oil passage is called full flow filter. When the engine is working, all lubricating oil is filtered through the filter; Parallel with it is called shunt filter). The primary filter I is connected in series in the main oil passage and is full flow type the secondary filter is connected in parallel in the main oil passage and is of split flow type. Modern automotive engines - generally have only a filter collector and a full flow oil filter. The coarse filter is used to filter the impurities with particle size of more than 0.05mm in the engine oil, while the fine filter is used to filter the fine impurities with particle size of more than 0.001mm.
