Abstract

Although diesel vehicles have high energy efficiency, the removal of emitted NO_xat low temperature persists as an important issue. This report presents an examination of low-temperature NO_xremoval using ozone injection and a plasma-lean NO_xtrap (LNT) catalyst system. Ozone is readily producible by a dielectric barrier discharge reactor using oxygen in air, and its injection to emitted NO enables oxidation to NO₂even at low temperatures. Results show that synergetic effects of ozone injection and plasma-LNT catalyst system enable low-temperature NO_xremoval.
