[0002] The air filter is an indispensable part of modern automobile engines. Its main function is to filter out dust, particles and other impurities in the air, protect the engine from wear and tear, and ensure that the engine can operate normally. The working principle of the air filter mainly depends on the filtering effect of its filter element. The filter element is usually made of paper or synthetic materials and has a multi-layer mesh structure to capture particles and pollutants in the air. When the air passes through the filter element, larger particles will be trapped by the filter element mesh, while smaller particles and pollutants will be captured by the filter element fibers, thereby achieving air purification.
