Oil Filter Shortcomings

There are two major shortcomings, and new products make up for the shortcomings, so it is necessary to use the new product strong magnetic oil filter.

Disadvantages of a: filter out the oil 60% of the impurities, the filter efficiency is low;

This is due to the existing oil filter, is to rely on a single paper filter hole to filter out the oil impurities in the filter, the filter paper pores smaller filter effect is better, but the oil through the ability of the worse. In order to solve the same filter paper pores can filter out the smallest particles of impurities, but also to supply a sufficient amount of engine oil can also be through this micro-hole through this contradiction. By the National Association of internal combustion engine industry filter, the best oil filter on the market, can only be designed to filter out the oil 60% impurity capacity, which is thousands of experiments after the maximum filter value. In actual use, there are 40% of the harmful impurities can not be effectively filtered by the paper filter, in this 40% impurity, because the ferromagnetic impurities are relatively small and hard, so the majority of ferromagnetic impurities, it is also on the engine damage maximum.

Disadvantages of two: under special conditions filter efficiency is zero;

In the bottom of the paper filter are provided with a bypass valve, which is designed in order to take into account the engine in the cold start oil viscosity or paper filter is partially blocked or all blocked, to ensure that the oil can be successfully returned to the engine and the design of the direct Oil flow channel. When the oil in the pump under the pressure to open the bypass valve, then by the bypass valve cycle back to the engine oil not only can not filter the paper filter, but also the original filter has been filtered out of large particles of impurities, Through the bypass valve back to the engine, to the engine to bring uninterrupted secondary wear. From the above two shortcomings can be seen on the paper filter hole than the impurities do not have a permanent role in the filter can only be equivalent to those of the paper filter core and embedded in the paper filter holes in the impurities play a permanent Of the filter effect, so the filter efficiency is very low.
