Title (EN) WIRE MESH MIXING TUBE
(FR) TUBE DE MÉLANGE DE TREILLIS MÉTALLIQUE
Abstract:
(EN) A mixer assembly for mixing an injected reductant with an exhaust gas output from a combustion engine includes an outer housing, a tubular inner housing, and an injector. The outer housing includes an outer wall defining an exhaust gas passageway that can receive exhaust gas. The inner housing is disposed within the outer housing and includes a longitudinal axis, a first end, a peripheral wall, and an outlet. The peripheral wall is at least partially formed by wire mesh. The outlet is disposed at a second end of the inner housing opposite the first end of the inner housing. The injector is fixed to the inner or outer housing to dose the reductant into the interior of the inner housing. The wire mesh includes openings to receive at least a portion of the exhaust gas. The outlet of the inner housing discharges a mixture of exhaust gas and reductant.
(FR) L'invention concerne un ensemble mélangeur pour mélanger un réducteur injecté avec une sortie de gaz d'échappement provenant d'un moteur à combustion. L'ensemble mélangeur comprend un boîtier externe, un boîtier interne tubulaire et un injecteur. Le boîtier externe comprend une paroi externe définissant un passage de gaz d'échappement qui peut recevoir un gaz d'échappement. Le boîtier interne est disposé à l'intérieur du boîtier externe et comprend un axe longitudinal, une première extrémité, une paroi périphérique et une sortie. La paroi périphérique est au moins partiellement formée par un treillis métallique. La sortie est disposée au niveau d'une seconde extrémité du boîtier interne à l'opposé de la première. L'injecteur est fixé au boîtier interne ou externe pour doser le réducteur à l'intérieur du boîtier interne. Le treillis métallique comprend des ouvertures pour recevoir au moins une partie du gaz d'échappement. La sortie du boîtier interne décharge un mélange de gaz d'échappement et de réducteur.
