Abstract
An 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. When a normal regeneration process is selected, the time at which acceleration regeneration request determination reserve period Telapses from the start of the normal regeneration process without the end of the normal regeneration process is time Tfor acceleration regeneration request determination, at which time, if the PM deposition amount estimation value is greater or equal to acceleration regeneration request determination value J, it is determined that there is the acceleration regeneration request. The DPF regeneration control unit allows the acceleration regeneration request information notifying unit to start notification of the acceleration regeneration request information.
