Analysis of air filter media design

This study uses experimental methods to analyze the filter material performance of vehicle air filters. The filter element of the air filter will directly affect the life of the engine. If the filter element cannot effectively filter out the dust in the air that is harmful to the engine, the engine will crack. This phenomenon will not only shorten the engine life, but also cause engine wear and indirect air pollution. In this study, two different filter materials were used, and the two filter materials were sprayed with three different oil contents of 7g, 14g and 20g respectively for testing. Analyze whether the oil content of the two filter materials affects the performance of the air filter. Its filtration performance is evaluated based on three items: ventilation resistance, dust capture capacity, and cleaning efficiency. As a result, generally speaking, if you want to protect the engine from being worn by dust, you need to use filter materials with high cleaning efficiency. However, high cleaning efficiency will also lead to high ventilation resistance. If the ventilation resistance is high, it will result in less air intake and reduced horsepower. Small. The results of this study can show the relationship between the oil content of filter paper and ventilation resistance, dust capture capacity and cleaning efficiency.
