Abstract
Nanofiber properties, methods of their production, and areas of their application have been presented. Parameters describing filtration materials with nanofibers addition were presented, and analyzed. Methodology for testing aerodynamic characteristics as well as characteristics of: efficiency, accuracy, and filter cartridges resistance with nanofibers addition, depending on the dust mass loading km were developed. Characteristic filtration parameters of the materials with nanofibers addition are presented. Five filtration inserts, differing in the filtration material with nanofibers addition, and without this layer were made. Test conditions were developed as well as a test stand was prepared. Aerodynamic characteristics tests of filter cartridges as well as filtration efficiency, accuracy, and flow resistance of standard (cellulose) cartridge, and the ones with nanofibers addition were performed. The positive effect of nanofiber layer on efficiency, and accuracy increase in the inlet engine air filtration was confirmed. Granulometric composition of air dust was assessed on a standard filter cartridge, and on a cartridge with nanofibers addition. Keywords: engine, air filter, nanofibers, filtration efficiency and accuracy, flow resistance, dust mass loading, grain size.
