Title (EN) INSTALLATION FOR DEPOLLUTING EXHAUST GASES, PARTICULARLY OF AN INTERNAL COMBUSTION ENGINE, AND METHOD FOR USING SUCH AN INSTALLATION
(FR) INSTALLATION POUR LA DEPOLLUTION DES GAZ D'ECHAPPEMENT, NOTAMMENT DE MOTEUR A COMBUSTION INTERNE, ET PROCEDE POUR L'UTILISATION D'UNE TELLE INSTALLATION
Abstract:
(EN) The present invention relates to an installation for depolluting exhaust gases circulating in an exhaust line (10), particularly of an internal combustion engine, comprising at least one catalysing means for the selective catalytic reduction of nitrogen oxides (NOx), at least one means for eliminating particles, a main tank (26) comprising at least one particle reducing agent, and means (20) for introducing the reducing agent into the exhaust line. According to the invention, the installation comprises means (30) for additivation of the reducing agent.
(FR) La présente invention concerne une installation pour la dépollution des gaz d'échappement circulant dans une ligne d'échappement (10), notamment d'un moteur à combustion interne, comprenant au moins un moyen de catalyse à réduction catalytique sélective des oxydes d'azote (NOx), au moins un moyen d'élimination de particules, un réservoir principal (26) comprenant au moins un agent réducteur des particules, et des moyens d'introduction (20) de l'agent réducteur dans la ligne d'échappement. Selon l'invention, l'installation comprend des moyens d'additivation (30) de l'agent réducteur.
