Abstract (en)
Provided is a plasma assisted exhaust emission control device with less electric power consumption and with no harmful gas discharged into atmosphere. A filter body (7) is constituted by porous members through which exhaust gas (2) passes for capturing of particulates in the exhaust gas (2) and is provided with rod-like and cylindrical electrodes (9,10) so as to generate plasma in the filter body (7), thereby providing a plasma regenerative particulate filter (11). The particulate filter (11) is accommodated in a filter casing (12) within an exhaust pipe (3). Oxidation catalysts (16,17) are arranged respectively upstream and downstream of and adjacent to the particular filter (11) in the filter casing (12) so as to obtain heat insulation effect to the particulate filter (11).
