APPARATUS FOR REGENERATION OF DIESEL PARTICULATE FILTER AND APPARATUS FOR REDUCTION OF DIESEL PARTICULATE MATTER HAVING THE SAME

摘要

PURPOSE: A diesel particulate filter regenerating device and a diesel particulate reduction device with the same are provided to enable the regeneration of a diesel particulate filter over the whole operating range of an engine. CONSTITUTION: A diesel particulate filter regenerating device comprises a preheating ignition part(200), an ignition combustion part(300), and a catalytic combustion part(400). The preheating ignition part comprises a plug member(210) which ignites a fuel and air mixture. The ignition combustion part, one side of which is connected to the preheating ignition part and the other side is connected to an exhaust pipe(V) connected to an engine(E), leads the combustion gas generated by the plug member to the exhaust pipe, raises the temperature of exhaust gas drawn in a diesel particulate filter(F) connected to the exhaust pipe, and leads unburned fuel to the exhaust pipe. The catalytic combustion part is provided in the downstream of the exhaust pipe in which the ignition combustion part is located and raises the temperature of exhaust gas drawn in the diesel particulate filter through catalytic combustion of vaporized fuel containing catalyst.
