装置。[Scope of Claim for Utility Model Registration] An exhaust gas after-treatment device for treating exhaust gas emitted from a diesel engine using low sulfur fuel, which is disposed in the flow path of the exhaust gas and A particulate filter that collects particulate matter; a filter regeneration heater disposed upstream of the particulate filter in the flow direction of exhaust gas; and a current supply circuit that supplies current to the filter regeneration heater. An exhaust gas after-treatment device characterized in that the exhaust gas contacting surface of the particulate filter is coated with a low-temperature active catalyst that acts at a relatively low temperature.
