Air filter primary filter and internal combustion engine
During the operation of an internal combustion engine, if impurities are present in the air sucked in, it can cause early wear and tear, indicating the importance of air filters for internal combustion engines.
With the development of internal combustion engine technology, the requirements for air filters are becoming increasingly high. Air filters have evolved from the initial oil bath and oil immersed air filters to clean and efficient paper air filters; From single stage air filters to dual stage air filters with various forms of primary filters.
At present, most internal combustion engines in China have adopted paper air filters, and in order to extend the lifespan of paper filter elements, most of them are equipped with coarse filters. Before dust containing air enters the paper filter element, it first passes through a coarse filter to filter out most of the dust in the air, and then further filtered by the air filter.
The working principle of the coarse filter of different air filters is the same, with different types, structures, sizes, arrangements, and materials.
