<p>An object of the present invention is to provide an exhaust gas processing device for a diesel engine, which can suppress fuel consumption deterioration and output reduction. To achieve the object, the exhaust gas processing device for a diesel engine includes a DPF, a PM deposition amount estimating unit for PM deposited in the DPF, a DPF regenerating unit, a DPF regeneration control unit, a storage unit, an acceleration regeneration request information notifying unit, an acceleration regeneration start operating unit, and a mode selecting unit, wherein when the permission mode of a normal regeneration process is selected, the time at which acceleration regeneration request determination reserve period T1 elapses from the start of the normal regeneration process in step S3 without the end of the normal regeneration process in step S6 is time T2 for acceleration regeneration request determination, and when at time T2 for acceleration regeneration request determination, the PM deposition amount estimation value is equal to or more than acceleration regeneration request determination value J2, it is determined that there is the acceleration regeneration request so that the DPF regeneration control unit allows the acceleration regeneration request information notifying unit to start the notification of the acceleration regeneration request information in step S 10.</p> |
