とした排出ガス後処理装置。 Particulate matter in the exhaust passage of the internal combustion engine is captured by a particulate trap, and the controller takes in information on the amount of particulate accumulated on the particulate trap, and the accumulated amount information is used as a threshold value for determining the regeneration time. In the exhaust gas after-treatment device, the incineration means is activated to regenerate the filter when the particulate trap is incinerated. An exhaust gas after-treatment device characterized in that when the maximum temperature value of is outside the permissible incineration temperature range, the threshold value is increased or decreased so that the maximum temperature value is maintained within the permissible incineration temperature range.
