デイーゼルパテイキユレート排気処理装置。[Claims for Utility Model Registration] (1) A filter member disposed in the exhaust gas flow path of a diesel engine that collects particulate matter in the exhaust gas, and an end portion of the filter member in the exhaust gas inflow direction. In a diesel particulate exhaust treatment device including a heater member disposed in close proximity to ignite and burn the particulate, there is provided a heater member disposed on the exhaust gas upstream side of the heater member for assisting in igniting and burning the particulate. a preheating filter; a catalyst supported on the preheating filter that reacts with unburned components in the exhaust gas; 1. A diesel particulate exhaust treatment device comprising: fuel injection timing delay means for delaying fuel injection timing of the diesel engine. (2) Registration of a utility model in which the fuel injection timing delay means delays the fuel injection timing prior to energizing the heater member when the integrated value of the number of revolutions of the diesel engine reaches a certain value. A diesel particulate exhaust treatment device according to claim 1. (3) The diesel particulate exhaust treatment device according to claim 1, wherein a bypass passage that bypasses the filter member is opened when the heater member is energized.
