Abstract

Dispositif d'échappement des produits de combustion de moteurs deux temps, qui comporte un catalyseur et dans lequel le coude d'échappement est raccordé à une chambre cylindrique séparée d'un amortisseur de bruit par une paroi de rétrodiffusion, le catalyseur (8) étant agencé à l'intérieur de la chambre (3) et maintenu dans un tube de sortie (7), qui est orienté depuis la paroi de rétrodiffusion (5) en direction du coude d'échappement (5), de manière à faire saillie librement, de préférence de façon équiaxe, dans une position identiquement largement éloignée de tous les côtés de la paroi de la chambre (3).Exhaust device for the combustion products of two-stroke engines, which comprises a catalyst and in which the exhaust elbow is connected to a cylindrical chamber separated from a noise damper by a backscatter wall, the catalyst (8) being arranged inside the chamber (3) and held in an outlet tube (7), which is oriented from the backscatter wall (5) towards the exhaust elbow (5), so as to project freely , preferably equiaxially, in a position identically far away from all sides of the wall of the chamber (3).
