Patent ID: 8747502

Claim:
A particulate matter reduction apparatus for a diesel engine, the articulate is matter reduction apparatus comprising: a housing configured to be placed on a flow path through which exhaust gas from the diesel engine is discharged; a filter configured to comprise a plurality of unit filter portions, each extending in a length direction of the housing and being accommodated in the housing; a plurality of unit electrodes configured to transmit electronic signals individually to the respective unit filter portions; and a control unit configured to control electronic signals provided to the unit electrodes and allow the unit filter portions to be heated independently, wherein: the control unit is further configured to assign the electronic signals sequentially to the respective unit filter portions, the unit filter portions which are adjacent to each other have a non-conductive adhesive layer interposed therebetween, the unit electrodes comprise first electrodes configured to be formed on an exhaust-gas inflow end of the unit filter portions and transmit an electronic signal in common to the unit filter portions, and second electrodes configured to be formed on an exhaust-gas outflow end of the unit filter portions and comprise portions electrically separated from one another according to corresponding unit filter portions, and the first and second electrodes induce current flow between the exhaust-gas inflow end and the exhaust-gas outflow end when a voltage exists between the first electrodes and the second electrodes.
