ABSTRACT:
In an exhaust gas purification system with a continuous regeneration type DPF device, when a collecting quantity (ΔPm) of PM exceeds a predetermined judgment collecting quantity (ΔPm0), a number-of-regeneration-times coefficient (Rc) serving as an index of the number of regeneration times to a travel distance is compared with a predetermined judgment coefficient value (R0). When the number-of-regeneration-times coefficient (Rc) is smaller than the predetermined judgment coefficient value (R0), automatic traveling regeneration is performed. If this condition is not met, manual regeneration is performed.
