Centrifugal oil filter has a rotor on a shaft, and there are two injection direction opposite nozzle, when the oil into the rotor from the nozzle out, the rotor will rotate quickly, so that the oil in the rotor body to get clean, the impurities in the oil is centrifugal thrown to the inner wall of the rotor, the nozzle out of the oil flow back to the oil sump. Centrifugal oil filter is characterized by stable performance, no need to replace the filter element, as long as the regular removal of the rotor, clean deposited dirt on the rotor wall can be reused. Its life is comparable to that of an engine. It has the disadvantage of complex structure, high price, unwieldy and so on.
　　Full-flow oil filter, as mentioned before, replaceable type, rotary type, split centrifugal type, etc., to filter all the oil into the system. The shunt filter only filters the oil supplied by 5%-10% of the oil pump. Splitter oil filters are fine filters, which are generally used in conjunction with full flow filters. Most low-power engines only use full-flow filter, while high-power diesel engines mostly use full-flow filter and shunt filter.
