ABSTRACT:
A system for purifying an exhaust gas includes a plasma unit and a catalyst unit. The plasma unit generates energetic plasma species which react with particulate matters and nitrogen oxides contained in the exhaust gas. The catalyst unit has a catalyst which reacts with the exhaust gas. The plasma unit is disposed upstream relative to the catalyst unit in a direction of flow of the exhaust gas and the system provides sequential purification for the particulate matters and the nitrogen oxides.
