Study of properties of nonwoven filter cartridges for the intake air of a car engine

Journal Title: Bulletin of the Military University of Technology - Year 2017, Vol 66, Issue 2

Abstract

The sources of atmospheric air pollution are presented. It has been shown that dust is a major component of the intake air of internal combustion engines. The impact of dust on the accelerated wear of the engine components and the influence of T-P-C system wear on engine operation were analysed. The parameters of the air filters are described and defined. The properties of nonwovens and papers, of which filters used in the filtration intake air internal combustion engines of motor vehicles are made, were analysed. Conditions and methodology for testing nonwoven air filter cartridge for passenger cars were developed. A research desk with a particle counter was presented. The results of the study on efficiency characteristics, filtration accuracy and flow resistance for three different filtration rates (three nonwoven cartridges) were presented. There were much smaller levels of efficiency (φw = 92÷98%) and accuracy for nonwoven filter contribution in comparison with paper ones (φw = 95.5÷99.9%). There were observed higher values of the absorbency factor km for nonwoven cartridge (km = 1000÷1300 g/m2) in relation to the paper cartridge (km = 190÷220 g/m2). Keywords: engine, air filter, nonwoven contribution, efficiency and accuracy of filtration, flow resistance, coefficient of dust absorbency, grain size
