Oil filter is divided into:
　　Centrifugal oil filter has a rotor sleeve on a shaft, and two jet nozzle in the opposite direction, when the oil into the rotor from the nozzle, the rotor will quickly turn the rotor body of the oil to be clean, The impurities in the oil are centrifuged onto the inner wall of the rotor and the oil from the nozzle returns to the oil pan. Centrifugal oil filter is characterized by stable performance, there is no need to replace the filter, as long as the regular removal of the rotor, cleaning the dirt deposited on the rotor wall can be re-used. Its life can be equivalent to the engine. Its disadvantage is the complex structure, higher prices, heavy and so on, the use of personnel have higher technical requirements.
　　Full-flow oil filter, as previously described interchangeable, spin-on, split centrifugal, etc., all the oil into the system for filtering. Split filter only filter pump oil supply of 5% -10% of the oil. Split-type oil filters are fine filter, it is generally used in conjunction with the full flow. Most low-power engines use only full-flow filters, more powerful diesel engines use full-flow plus split-flow filtration units.
