Title (EN) APPARATUS FOR FACILITATING REDUCTANT DECOMPOSITION AND MIXING
(FR) APPAREIL FACILITANT LA DÉCOMPOSITION ET LE MÉLANGE D'AGENTS RÉDUCTEURS
Abstract:
(EN) According to one embodiment, an apparatus (50) for mounting to an inner wall (33) of an exhaust tube (32) includes a tube engagement surface (52) and an exhaust engagement surface (54A). The tube engagement surface comprises a convex surface of a constant first radius of curvature about a first axis. The exhaust engagement surface is adjacent the tube engagement surface, and includes a concave surface of a second radius of curvature about a second axis generally perpendicular to the first axis.
(FR) Selon un mode de réalisation, un appareil (50) pour le montage d'un tube d'échappement (32) sur une paroi interne (33) comprend une surface en contact avec le tube (52) et une surface en contact avec l'échappement (54A). La surface en contact avec le tube comprend une surface convexe ayant un premier rayon de courbure constant autour d'un premier axe. La surface en contact avec l'échappement est adjacente à la surface en contact avec le tube, et comprend une surface concave ayant un second rayon de courbure autour d'un second axe généralement perpendiculaire au premier axe.
