<P>PROBLEM TO BE SOLVED: To realize a plasma assist type exhaust emission control device reducing electric power consumption and discharging no noxious gas into the atmosphere. <P>SOLUTION: In a filter main body 7 comprised of a porous material for collecting particulates in exhaust gas 2 by making the exhaust gas 2 pass, a plasma regeneration type particulate filter 11 is constituted by providing bar-shaped electrodes 9 and tubular electrodes 10 to generate plasma inside the filter main body 7. The plasma regeneration type particulate filter 11 is stored inside a filter case 12 in the middle of an exhaust pipe 3. Oxidation catalysts 16, 17 are arranged in the vicinity of forward and backward positions of the plasma regeneration type particulate filter 11 inside the filter case 21 so as to obtain insulation effectiveness with respect to the plasma regeneration type particulate filter 11. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
