  "textContent": "Estimated values of an amount of accumulated particulate matter on a particulate filter (4) are obtained before initiation of a forceful regeneration operation of the particulate filter (4). A maximum operating time period of the regeneration operation is set based on the estimated values of the amount of accumulated particulate matter. The particulate filter (4) is regenerated in the regeneration operation by performing post fuel injection in the diesel engine during each exhaust stroke of the diesel engine to supply fuel to the particulate filter (4) and thereby to remove the particulate matter from the particulate filter (4) through use of combustion heat of the supplied fuel upon combustion of the supplied fuel.",
