Abstract

Le dispositif (10) comporte un conduit amont (12), s'étendant le long d'une première direction (X1), et dans lequel est logé au moins un organe (14) de purification, un premier conduit aval (16), s'étendant le long d'une seconde direction (X2), et dans lequel est logé au moins un échangeur de chaleur (18), et un deuxième conduit aval (28), destiné à être connecté à un tube de sortie de gaz d'échappement. Il comporte une chambre intermédiaire (30) comprenant : une entrée (32) de gaz d'échappement communiquant avec le conduit amont (12), en aval de l'organe de purification (14), une première sortie de gaz d'échappement (34) communiquant avec le premier conduit aval (16), et une seconde sortie de gaz d'échappement (36) communiquant avec le second conduit aval (28). La première direction (X1) et la seconde direction (X2) forment entre elles un angle (γ) compris entre 0° et 90°.
