During an intake stroke in an engine, outside air enters from an air cleaner intake pipe into a cylinder. For an engine intake system, it is required that the intake resistance is small, the gas flow is smooth, and the suction noise is small. The air filter not only plays a role in filtering air in an air inlet system, but also is an important part for ensuring the work performance of the engine and reducing the air suction noise.
