Abstract
An exhaust gas treatment system for an internal combustion engine includes an exhaust gas pathway configured to receive exhaust gas from the internal combustion engine and a non-thermal plasma generator positioned in the exhaust gas pathway. The non-thermal plasma generator is configured to increase a proportion of nitrogen dioxide in the exhaust gas. The system also includes a first treatment element positioned in the exhaust gas pathway downstream of the non-thermal plasma generator and a second treatment element positioned in the exhaust gas pathway downstream of the first treatment element. At least one of the first treatment element or the second treatment element includes a combined selective catalytic reduction and diesel particulate filter (SCR+F) element.
