There are two major shortcomings, and the new products make up for the shortcomings, so it is necessary to use the new product strong magnetic oil filter .
Disadvantage 1: filter out 60% of impurities in engine oil, low filtration efficiency;
This is because the existing oil filters rely on a single paper filter element to intercept and filter out harmful impurities in the oil. The smaller the micropores of the filter paper, the better the filtering effect, but the worse the oil passing ability. In order to solve the contradiction that the same filter paper micropores can not only remove the smallest particles of impurities, but also allow the engine to supply a sufficient amount of engine oil through the micropores. After the National Internal Combustion Engine Industry Association Filter Branch, the best oil filters on the market can only be designed to remove 60% of impurities in the oil. This is the maximum filtration value obtained after thousands of experiments. In actual use, there are still 40% of harmful impurities that cannot be effectively filtered by a paper filter element. Among these 40% of impurities, ferromagnetic impurities are relatively small and hard, so most of them are ferromagnetic impurities, which will damage the engine. maximum.
Disadvantage 2: The filtration efficiency is zero under special conditions;
The bottom of the paper filter element is provided with a bypass valve. This is a direct design in order to ensure that the engine oil can circulate back to the engine smoothly when the engine is cold-started when the oil viscosity is large or the paper filter element is partially or completely blocked. 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 only not be filtered by the paper filter element, but also the large particulate impurities that have been filtered out by the paper filter element. Re-rush back to 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 that are larger or smaller than the micropores of the paper filter element cannot have a permanent filtering effect. The filtration effect is very low.
