Title
(FR) ELEMENT D'ECHAPPEMENT DE LIGNE D'ECHAPPEMENT DES GAZ
Abstract
(FR)
L'invention concerne un élément (5) d'échappement que comporte une ligne d'échappement (1) des gaz issus de la combustion d'un carburant au sein d'un moteur thermique (2) et comportant, dans le sens de l'écoulement des gaz, d'une part, un premier moyen de raccordement (8) à une conduite (3) amont d'acheminement des gaz provenant du moteur (2), d'autre part, un premier conduit (9) et un second conduit (10) d'échappement, ces deux conduits (9 ; 10) étant parallèles et raccordés audit premier moyen de raccordement (8) et, d'autre part encore, un second moyen de raccordement (13) à une conduite avale (6) d'évacuation des gaz et raccordé auxdits conduits d'échappement parallèles (9 ; 10).Cet élément (5 est caractérisé par le fait que, d'une part, le premier conduit (9) comporte un élément de dépollution (11), d'autre part, le second conduit (10) comporte un silencieux (12) et, d'autre part encore, le second moyen de raccordement (13) est constitué par une vanne trois voies (14).
