Abstract (en)

[origin: EP1574680A1] Automobile engine exhaust gas purification system comprises inlet channels with a open front end and a closed rear end, outlet channels with a closed front end and a open rear end, an oxidation catalyst at the front end of the inlet channels, and a catalyst-regenerating plasma discharge system at the rear end of the inlet channels. Automobile engine exhaust gas purification system comprises inlet channels (1) with a open front end and a closed rear end, outlet channels (2) with a closed front end and a open rear end, an oxidation catalyst (5a) comprising a layer of catalyst-impregnated material at the front end of the inlet channels, and a catalyst-regenerating plasma discharge system comprising electrodes (6, 7) that are embedded in a dielectric barrier (5b) at the rear end of the inlet channels and are connected to an electricity supply. An independent claim is also included for an automobile exhaust train comprising a system as above.
