Abstract
When a forced regeneration is restarted after interrupting the forced regeneration, and in at least any one of cases where the collecting quantity area (Rpj) detected by the collecting quantity area detection means (C) is in another collecting quantity area having a collecting quantity larger than that of the collecting quantity area (Rpi) immediately after interruption, or where the travel distance area (Rmj) detected by the travel distance area detection means (C) is in another travel distance area, having a travel distance larger than that of the travel distance area (Rmi) immediately after interruption, the forced regeneration is performed from the start, and in other case, the forced regeneration is performed for the remained period of time of the previous forced regeneration, continuing to the previous forced regeneration. Thereby, in the case of an exhaust gas purification system (), provided with a DPF device (), when the forced regeneration for the DPF device () is restarted after interruption, it is possible to sufficiently burn and remove the PM accumulated in the DPF () and moreover, efficiently regenerate the DPF ().
