Abstract
TITRE : Mélangeur de post traitement de gaz d’échappement L’invention concerne un mélangeur (1) de post traitement de gaz d’échappement pour mélanger le gaz d’échappement avec un réducteur, tel un fluide d’échappement diesel pour réduction catalytique sélective, comprenant une chambre de mélange (2) au travers de laquelle le gaz d’échappement circule, depuis une entrée (4) jusqu’à une sortie (5), et un pulvérisateur (3) de réducteur, apte à pulvériser un réducteur dans la chambre de mélange (2), où la chambre de mélange (2) comprend une canalisation (6) rectiligne selon un axe (A) et le pulvérisateur (3) est disposé en partie amont de la canalisation (6) rectiligne et orienté de manière à pulvériser vers l’aval sensiblement parallèlement à l’axe (A).
