Title (EN) UNIFORM FLOW DISTRIBUTION OF A REDUCTANT
(FR) DISTRIBUTION DE FLUX UNIFORME D'UN AGENT RÉDUCTEUR
Abstract:
(EN) A system (212) for uniform flow distribution of a reductant is disclosed. The system (212) includes an injector lance (218) and a diffuser assembly (220). The injector lance (218) further includes a reductant supply conduit (222) and an injector nozzle (224). The reductant supply conduit (222) extends into an internal diameter (D) of an exhaust conduit (106) from a first end (308) of the exhaust conduit (106) towards a second end (310) of the exhaust conduit (106). The injector lance (218) is in communication with and extends perpendicular to the reductant supply conduit (222). The injector lance (218) is located along a longitudinal axis of the exhaust conduit (106). The diffuser assembly (220) is further collocated or integral with the injector lance (218).
(FR) La présente invention concerne un système (212) de distribution de flux uniforme d'un agent réducteur. Le système (212) comporte une lance d'injection (218) et un ensemble diffuseur (220). La lance d'injection (218) comporte également un conduit d'alimentation en agent réducteur (222) et une buse d'injection (224). Le conduit d'alimentation en agent réducteur (222) se prolonge dans un diamètre interne (D) d'un conduit d'évacuation (106) depuis une première extrémité (308) du conduit d'évacuation (106) jusqu'à une seconde extrémité (310) du conduit d'évacuation (106). La lance d'injection (218) est en communication avec le conduit d'alimentation en agent réducteur (222) et s'étend perpendiculairement à celui-ci. La lance d'injection (218) est située le long d'un axe longitudinal du conduit d'évacuation (106). L'ensemble diffuseur (220) est en outre co-implanté ou intégré avec la lance d'injection (218).
