ABSTRACT:
The present invention is characterized in that a casing2connected to an exhaust system8,a honeycomb filter3placed in the inside of the casing2,the honeycomb filter having a plurality of cells partitioned by partition walls, and plasma generation electrodes6placed being faced each other by sandwiching the honeycomb filter there are included, particulate matter contained in an exhaust gas is collected by the honeycomb filter3,nitrogen monoxide contained in the exhaust gas is oxidized to nitrogen dioxide by nonthermal plasma generated between a pulse electrode4and an earth electrode5constituting the plasma generation electrodes6,combustible materials in the particulate matter collected and deposited on the surface of the partition walls are removed through oxidation by the nitrogen dioxide produced. As a result, the honeycomb filter3can be regenerated.
