特徴とするデイーゼルエンジンの排気浄化装置。 In a diesel engine exhaust purification system, in which a particulate trap filter is interposed in the engine exhaust passage and a regeneration heat source supply means for reburning the collected particulate is provided, the trap filter is used as the regeneration heat source supply means. A burner device that blows combustion gas toward the front of the filter is installed on the side, and an electric heater that surrounds and heats the entire outer periphery of the filter is installed. Temperature detection means are installed at each part of the front, center, and rear of the trap filter. Exhaust purification of a diesel engine, characterized in that it is provided with a controller that operates an electric heater for a predetermined time and intermittently controls the drive of a burner device based on detection signals from each temperature detection means while the electric heater is in operation. Device.
