A full-current oil filter, as described above, the elongated, rotary flexible, split centrifugal, etc., filters all oil entering the system. Diversion filter is only 5% -10% of oil filters oil pump. Diversion oil filters are fine filters, which are generally used in full-flow. Most small power engines use only a full-current filter with a larger power diesel engine with a full-current addition of shunt filtering devices.

The centrifugal oil filter has a graphite rotor sleeve on a shaft and has two nozzles opposite to the inadequate direction. When the oil enters the graphite rotor, the graphite rotor quickly rotates, so that the graphite rotor The oil is cleaned, the impurities in the oil are centrifuged to the inner wall of the graphite rotor, and the oil flows back to the oil bottom shell. The centrifugal oil filter is characterized by stability, structure variable, no demand replacement, only need to be disassembled in the graphite rotor, and the fouling of the deposited on the wall of the graphite rotor can be applied. Its life can be equivalent to the engine. Its lack is that the structure is complex, high, cumbersome, etc. have high technical requirements for employers.
