METHOD FOR REDUCING THE NITROUS OXIDE IN MOTOR VEHICLE EXHAUST GASES

摘要

The invention relates to the power train of a motor vehicle, including an internal combustion engine (1; 1'), an exhaust line (3; 3'), a device for post-treating nitrogen oxides (NOx) (4; 4') in the exhaust gases for reducing the amount of nitrogen oxides emitted into the atmosphere, and a device for post-treating nitrous oxide (N2O) (7; 7') in the exhaust gas for reducing the amount of nitrous oxide emitted into the atmosphere, characterised in that the device for post-treating nitrous oxide (N2O) (7; 7') is arranged downstream from the device for post-treating nitrogen oxides (NOx) (4; 4') in the exhaust line (3; 3').
