摘要： An exhaust gas purification device includes an exhaust gas after-treatment device provided in an exhaust passage of an internal combustion engine, and has an oxidation catalyst and a DPF or diesel particulate filter. The exhaust gas purification device also includes an exhaust pipe injector which feeds a fuel to the oxidation catalyst, and a control unit which controls regeneration of the filter by supplying the oxidation catalyst with the fuel from the exhaust pipe injector. The control unit determines whether the filter is in a regeneration-possible state, i.e., whether the oxidation catalyst is maintained at a high temperature allowing regeneration of the filter. If the control unit determines during regeneration control of the filter that the filter is not in the regeneration-possible state, then the control unit halts the regeneration control until the regeneration-possible state is reached.
