촉매연소기를 이용한 소형 경유 운행차용 매연여과장치의 강제 재생 특성

Light duty diesel vehicles are considered as one of major sources of particulate emissions in many cities, and the start of the retrofit program for the vehicles is expected in near future in Korea. One of the problems of the retrofit of the light duty diesel vehicles is that the exhaust gas temperature is too low to apply passive regeneration type DPF systems. This study introduces a new DPF regeneration technology using a catalytic combustor. This study shows the principle and characteristics of DPF regeneration by the catalytic combustor and suggests it's proper control method for better regeneration.
