Abstract
(EN)
This mixing member, which, in an exhaust pipe, mixes exhaust gas and a reducing agent supplied in a supply direction that is inclined with respect to the emission direction of exhaust gas flow, has a main body comprising a gas inlet, a gas outlet, and a gas flow path which connects the gas inlet and the gas outlet and inside of which the exhaust gas and the reducing agent are mixed. When arranged inside the exhaust pipe, the gas inlet is provided in the end surface of the main body part that is positioned on the upstream side in the emission direction. The end surface is arranged inclined relative to the emission direction so as to face upstream in the supply direction of the reducing agent. The gas flow path is inclined relative to the supply direction and extends in parallel with the emission direction.

L'invention concerne un élément de mélange, qui, dans un tuyau d'échappement, mélange un gaz d'échappement et un agent réducteur fourni dans une direction d'alimentation qui est inclinée par rapport à la direction d'émission de l'écoulement de gaz d'échappement, comprend un corps principal comprenant une entrée de gaz, une sortie de gaz, et un trajet d'écoulement de gaz qui relie l'entrée de gaz et la sortie de gaz et à l'intérieur duquel sont mélangés les gaz d'échappement et l'agent réducteur. Lorsqu'elle est agencé à l'intérieur du tuyau d'échappement, l'entrée de gaz est disposée dans la surface d'extrémité de la partie de corps principal qui est positionnée sur le côté amont dans la direction d'émission. La surface d'extrémité est agencée inclinée par rapport à la direction d'émission de façon à être tournée vers l'amont dans la direction d'alimentation de l'agent réducteur. Le trajet d'écoulement de gaz est incliné par rapport à la direction d'alimentation et s'étend parallèlement à la direction d'émission.
