Title
(EN) EXHAUST COMPONENT OF GAS EXHAUST LINE
(FR) ELEMENT D'ECHAPPEMENT DE LIGNE D'ECHAPPEMENT DES GAZ.
Abstract
(EN)
The invention relates to an exhaust component (5) in a gas exhaust line (1) for gases produced by the combustion of a fuel in a heat engine (2) and having, in the gas flow direction, firstly a first means of connection (8) to an upstream pipe (3) carrying gases from the engine (2), secondly a first (9) and a second (10) exhaust tube, these two tubes (9, 10) being parallel and being connected to said first means of connection (8), and thirdly a second means of connection (13), to a downstream gas discharge pipe (6), connected to said parallel exhaust tubes (9, 10). This component (5) is characterized in that, firstly the first tube (9) comprises a depolluting component (11), secondly the second tube (10) comprises a silencer (12), and thirdly the second means of connection (13) is a three-way valve (14).
(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).
