Abstract (en)
[origin: EP1020620A1] Ozone generator for exhaust gas purification injects ozone (8) into the exhaust line just ahead of the oxidation catalyst Preferred Features: The exhaust line includes a catalyst (5), especially an oxidation catalyst, and/or a gas mixer (6). Ozone enters the exhaust gases, before they enter the catalyst and/or mixer. The point of introduction is spaced (b) upstream of the catalyst and/or mixer. The source is in the exhaust line itself or in a line introducing air or secondary air, upstream (b) of the catalyst and/or mixer. The ozone source is an ozone generator (7), supplied with fresh air or exhaust gases.
