Title (EN) EXHAUST GAS AFTER TREATMENT SYSTEM (EATS)
(FR) SYSTÈME DE POST-TRAITEMENT DE GAZ D'ÉCHAPPEMENT (EATS)
Abstract: front page image
(EN)The invention relates to an exhaust gas after treatment system comprising a diesel particulate filter unit arranged downstream of a diesel engine, a NO2 reduction catalyst arranged downstream of said diesel particulate filter, a selective catalytic reduction (SCR) arrangement arranged downstream of said NO2 reduction catalyst, a first injector for feeding reducing agent into the exhaust gas arranged downstream said particulate filter and upstream said NO2 reduction catalyst, a second injector for feeding reducing agent into the exhaust gas arranged downstream said NO2 reduction catalyst and upstream said selective catalytic reduction (SCR) arrangement. The invention also relates to an exhaust gas after treatment method.
(FR)L'invention concerne un système de post-traitement de gaz d'échappement comprenant une unité de filtrage de particules diesel placé en aval d'un moteur diesel, un catalyseur de réduction de NO2 positionné en aval dudit filtre de particules diesel, un dispositif de réduction sélective catalytique (SRC) disposé en aval dudit catalyseur de réduction de NO2, un premier injecteur d'alimentation de l'agent de réduction dans le gaz d'échappement positionné en aval dudit filtre de particules et en amont du catalyseur de réduction de NO2, et un second injecteur d'alimentation de l'agent de réduction dans le gaz d'échappement disposé en aval dudit catayseur de réduction de NO2 et en amont du dispositif de réduction sélective catalytique (SCR). L'invention concerne également un procédé de post-traitement de gaz d'échappement.
