Abstract (en)

The system has an exhaust pipe (16) with a reactor (18) producing non-thermal plasma from exhaust gas received in its inlet. A catalyst (22) arranged in a downstream of the reactor reduces nitrogen oxide. The catalyst has different catalytic units (22a, 22b, 22c) including thermal windows for different catalytic activities. The windows are complementary and are operated in high, medium and low temperatures, respectively.
