Abstract

La présente invention concerne un procédé d'optimisation de la consommation d'agent réducteur sous forme d'ammoniac dans une ligne (1) d'échappement comprenant des premier et deuxième systèmes de réduction (2, 3) catalytique sélective, le deuxième système (3) étant disposé en aval du premier système (2) en étant éloigné par un espacement (4), un surplus d'ammoniac non utilisé passant par la ligne (1) d'échappement, la température dans la ligne (1) d'échappement au niveau du deuxième système (3) étant mesurée ou estimée. Quand la température au niveau du deuxième système (3) dépasse une première valeur maximale, ou quand une vitesse d'élévation de température calculée est supérieure à une vitesse d'élévation prédéterminée, sous condition que la température au niveau du deuxième système (3) soit supérieure à une deuxième valeur maximale inférieure à la première valeur maximale, il est effectué un refroidissement forcé dans l'espacement (4) entre les premier et deuxième systèmes (2, 3).
