The centrifugal oil filters has a rotor sleeved on a shaft, and has two nozzles with opposite spraying directions. When the oil enters the rotor and exits from the nozzle, the rotor rotates quickly to clean the oil in the rotor body. The impurities in the oil are centrifuged to the inner wall of the rotor, and the oil from the nozzle flows back to the oil pan. The characteristics of the centrifugal oil filter are stable performance, there is no filter element that needs to be replaced, as long as the rotor is regularly disassembled, the dirt deposited on the rotor wall can be cleaned and reused. Its life can be equivalent to the engine. Its disadvantages are complex structure, high price, bulky, etc., and high technical requirements for users.
Full-flow oil filters, such as the replaceable, spin-on, and split-centrifugal type described above, filter all the oil that enters the system. The split filter filters only 5% -10% of the oil supplied by the oil pump. Split-flow oil filters are fine filters, which are generally used in combination with full-flow filters. Most low-power engines only use full-flow filters, and diesel engines with larger powers often use full-flow plus split-flow filtering devices.
