In this paper, we studied about active regeneration characteristics of wall flow type Metal Fiber DPF. Active re-generation rate of DPF is analysed into soot loading quantity, regeneration time, heat insulation thickness, and so on. By the measurement of temperature distribution DPF inner side during regeneration, soot loading limit of metal fiber DPF is concluded. In case of SiC filter, after 5 time active regeneration, macro crack is generated across the filter, but metal fiber filter don't fragile till 7 time regeneration. In this study, metal fiber DPF has over 9g/L soot loading capacity. During 12weeks vehicle test of the DPF, maximum pressure drop is 250mbar, but after active regeneration the pressure drop is lowed to 30mbar.
