Introduction of engine air filter filter
The main function of the engine air filter is to filter the dust and sand in the air, ensure the quality of the air entering the cylinder, and prolong the service life of the engine. It is an important part of the car engine.
Existing studies have shown that: 70% of the early damage of automobile engines is related to the air filter, and its quality directly affects the reliability and service life of the engine. It is also one of the mandatory quality inspection items for internal combustion engines. The performance of the air filter depends on The structure of the filter itself, the selected filter element material and its processing quality.
At present, there is a technical bottleneck in the further improvement of the structural performance of the air filter element. Although great progress has been made in the development of filter element materials at home and abroad, the experimental research process is cumbersome. The structure of the air filter element is of great significance to improve the efficiency of air filter research and development.
At present, the air filters commonly used in engines mainly include inertial oil bath air filters, paper dry air filters, polyurethane filter air filters, etc. Inertial oil bath air filters have low filtration efficiency, high quality and low cost. High, inconvenient maintenance and other disadvantages have been gradually eliminated in automobile engines. Paper dry air filter elements are currently the most widely used air filter elements for automobiles, mainly including microporous filter paper filter elements, non-woven filter elements, fiber filter elements, etc. .
