The invention relates to a product for the depollution of exhaust gases, especially from an internal combustion engine, said product being a mixture of an additive for treating the particles and a reducing agent for eliminating the nitrogen oxides (NOx). According to the invention, the product comprises a mixture of a reducing agent containing ammonia or a compound generating ammonia by decomposition, or a hydrocarbon from a hydrocarbonated substance which is oxygenated or not, and an additive for catalysing the oxidation of the particles. La présente invention concerne un produit pour la dépollution de gaz d'échappement, notamment de moteur à combustion interne, ledit produit étant un mélange d'un additif pour le traitement des particules et d'un agent réducteur pour l'élimination des oxydes d'azote (NOx). Selon l'invention, le produit comprend un mélange d'un agent réducteur contenant de l'ammoniac ou un composé générant de l'ammoniac par décomposition, ou un hydrocarbure provenant d'une substance hydrocarbonée oxygénée ou non, et d'un additif pour catalyser l'oxydation des particules.
