Abstract
When an estimated value (A value) of an accumulation amount in a filter for trapping particulate matter reaches a prescribed value A1 corresponding to a prescribed accumulation amount Qm of the particulate matter and ash (S12), the forced regeneration of the filter is performed (S20); and when the estimated value (A value) reaches the prescribed value A1 again before the elapsed time since the completion of the forced regeneration of the filter reaches a prescribed time period T1 (S12, S14), it is judged that the amount of the ash accumulated in the filter is equal to or larger than a regulation amount (cleaning is required).
