AFTER-TREATMENT SYSTEM

An after-treatment system (200) includes, in series along an exhaust gas flow direction through the after-treatment system (200): a diesel oxidation catalyst (DOC) (108) or a passive NOx adsorber (PNA) (203), a diesel exhaust fluid (DEF) (121) delivery device, a soot-reducing device and a selective...

Beschreibung
Zusammenfassung:	An after-treatment system (200) includes, in series along an exhaust gas flow direction through the after-treatment system (200): a diesel oxidation catalyst (DOC) (108) or a passive NOx adsorber (PNA) (203), a diesel exhaust fluid (DEF) (121) delivery device, a soot-reducing device and a selective catalytic reduction (SCR) catalyst, which may also include an additional PNA (203). L'invention concerne un système de post-traitement (200) comprenant en série le long d'une direction d'écoulement de gaz d'échappement à travers lui: un catalyseur d'oxydation diesel (DOC) (108) ou un adsorbeur de NOx passif (PNA) (203), un dispositif de distribution de fluide d'échappement diesel (DEF) (121), un dispositif de réduction de suie et un catalyseur de réduction catalytique sélective (SCR), qui peut également comprendre un PNA supplémentaire (203).
