Impact of Permeability and Folding on Products

Permeability and folding are crucial factors influencing the performance and efficiency of filters. They significantly impact the functionality and lifespan of automotive filters.

Permeability: For air filters, permeability is essential. High-permeability paper allows more fresh air to enter the engine, improving combustion efficiency and driving performance. If permeability is insufficient, the engine may lose power due to inadequate oxygen supply. Permeability is enhanced by controlling pore size, fiber spacing, and fiber type.

Folding Method: The folding of filter paper is designed to increase its filtration surface area, thereby improving filtration efficiency. More filtration surface means more particles can be captured, extending the paper's lifespan. Different folding methods can affect the stability and structure of the paper. Common folding methods include pleats, waveforms, and composite types.

In summary, selecting automotive filter paper is a complex engineering task that requires balancing permeability and filtration efficiency. Different materials and manufacturing processes can meet the needs of various engine conditions. To ensure optimal engine performance under different conditions, manufacturers carefully select and test filter paper. For car owners, regularly replacing air and oil filters is essential for maintaining engine health.
