A diesel particulate filter (DPF) using porous metal for a filter, due to its high thermal conductivity, and a radiation heater for a regeneration device, due to its uniform distribution of temperature, has been developed. When high trapping efficiency is required, filter thickness should be increased. However, the thicker filter has a problem of low regeneration efficiency caused by the declination of temperature in the direction of thickness in the filter. In order to improve regeneration efficiency, a filter-heater structure which achieves uniform distribution of temperature was designed by using computer simulation and confirmed good regeneration efficiency of this structure in the experiment.
