Abstract

La présente invention a pour objet l’utilisation, pour prévenir la formation de dépôts et/ou réduire les dépôts dans la conduite acheminant les gaz d’échappement en sortie d’un moteur vers un dispositif de réduction catalytique sélective des oxydes d’azote, d’une composition aqueuse comprenant :- au moins un agent réducteur des oxydes d’azote et/ou au moins un précurseur d’un tel agent, et- au moins un composé d’un ou plusieurs métaux choisis parmi les métaux suivants : Fe, Cu, Ni, Co, Zn, Mn, Mg, Ti, V, Sr, Pt, Ce, Ca, Li, Na, et Nb. La présente invention a également pour objet une méthode pour prévenir ou réduire de tels dépôts par injection de ladite composition aqueuse dans ladite conduite. Figure 1
