Now young people like to car as their vehicle, in the new car warranty, filter
, also known as the not can replace the product, but after shelf life, when we use will be wary, now tell you how to carefully filter manufacturer
Is a use of the filter in the test when we in order to meet the rated engine intake air inflow of the original resistance requirements, we adopt the SAE standard test bed.
When choosing products try to choose the original engine products, its performance, fuel economy and reliability are fully match.
Rated air inflow is used by the engine is to meet less than the rated air inflow flow filter parameters of this one principle, using resistance to tension, the original air intake resistance and filtration precision, thickness is in conformity with the requirements of the standard of the domestic general accuracy is 80 microns, filter paper filter precision of the ordinary 20 microns, efficient filter paper has 2 microns its filtering precision, so the import of oil extraction machine air filtration accuracy requirement is 5 microns, homebred not less than 20 microns.
We mainly testing four aspects, traffic -
Resistance test, is primarily to test the air flow loss.
Try the original filtration efficiency, can be calculated filter dust collection efficiency, requirements for general is above 99%, and the original inlet resistance test, the air intake resistance should be 9, rated capacity through filter cartridge, inlet and two outlet pressure difference should not exceed 3.
2 kpa, and more than words can make the engine smoke.
Another is ChuChen ability and the accumulation efficiency test, in 7 - resistance and pressure
Dust between 46 kpa, also cannot too much, too much will make the engine power decrease, affect the use.
Listened to the filter manufacturer to introduce is to understand a little bit, if you have not understand advisory welcome to buy.
