What is the basis of engine air filter design?

Motorcycles and cars travel on urban and rural roads. Good road air contains 0.0003-0.001g/m³ aerosol suspended particles. In fact, the aerosol suspended particles on most urban roads, rural gravel roads are 0.01-0.013g/m³, dirt roads under harsh conditions are 0.4-0.45g/m³, and construction sites can reach 0.5-1g/m³. When the dust content in the air reaches 0.8-1.2g/m³, the road completely loses visibility.
If these dusts in the air enter the engine, they will cause very large wear on the cylinder and the wash ring. This places very high demands on the air filter. Bowei’s air filter can effectively prevent these dust from entering your engine. We have done engine tests and fed different engines with 15g of dust particles. The engine speed and load were fixed (the speed was half of the rated speed, and the torque was half of the maximum torque). The engine was run-in before the test. The wear of the cylinder was measured by the notch method. The test results show that the dust material of 7-40μm is the most serious for both the cylinder and the piston. This damage accounts for 80% of the total damage, so we require that the air filter must filter out all impurities with a particle size of 7-40μm. Bowei’s non-woven air filter uses chemical fiber as the main raw material. The fiber characteristics, fiber length and fiber size can be arbitrarily selected. It can be thickened or designed as a low-resistance sheet during design, and it has durability. We are your best choice for air filters for motorcycles or modified cars.
