Disadvantages: under special conditions, the filtration efficiency is zero;
At the bottom of the paper filter is provided with a bypass valve, which is designed to take into account the engine in the cold start oil viscosity or paper filter is partially or completely blocked, to ensure the smooth circulation of oil back to the engine and the direct oil flow channel. When the oil opens the bypass valve under the pressure of the oil pump, the oil circulating back to the engine through the bypass valve will not be filtered by the paper filter core, but also the large particles of impurities that have been filtered out by the paper filter core will be washed back into the engine through the bypass valve, bringing uninterrupted secondary wear to the engine. From the above two shortcomings, it can be seen that the impurities greater than or less than the paper filter core microhole can not play a permanent filtration role, only for those equivalent to the paper filter core microhole and embedded into the paper filter core microhole impurities play a permanent filtration role, so the filtration efficiency is very low.
