Fine particles have the greatest demonstrated impact on human health. Their small size allows them to get deep into the lungs and from there they can reach or trigger inflammation in the lung, blood vessels or the heart, and perhaps other organs. Recently many studies have been performed about fine particles, specially nano particle less than 100㎚ size. In this study, we have performed experimental study on SFC reduction characteristics of emission, specially PM and PN(nano particle) and confirmed whether SFC have an advantage of reduction of particulate matter. EEPS measured the sample gas directly extracted from the tailpipe and used first dilutor between tailpipe and EEPS. We found that SFC reduced PM about 49% and PN about 62% and have a high reduction performance of nano particles.
