ス後処理装置。[Scope of Claim for Utility Model Registration] In an exhaust gas after-treatment device that processes exhaust gas emitted from a diesel engine, there is a particulate filter installed in the flow path of the exhaust gas to collect particulate in the exhaust gas. a filter, a first heater for filter regeneration disposed upstream of the particulate filter in the flow direction of exhaust gas, and a DC power supply circuit that selectively supplies DC power from an on-board battery to the first heater. a second heater disposed upstream of the first heater in the exhaust gas flow direction and connected in series with the first heater; and a second heater disposed upstream of the second heater in the exhaust gas flow direction. the first heater and the second heater connected in series with each other.
The heater is equipped with an AC power supply circuit that selectively supplies an untransformed AC power source provided outside the vehicle, and the second heater is operated as a resistor when the AC power source is connected. Exhaust gas after-treatment equipment.
