Title
(EN) A MOTOR VEHICLE COMPRISING A COMBUSTION ENGINE AND EXHAUST SYSTEM
(FR) MOTEUR THERMIQUE ET VÉHICULE MOTORISÉ ASSOCIÉ
Abstract
(EN)
The present subject matter provides a combustion engine (141) for a motor vehicle (101). An exhaust system (300) includes a primary receiving portion (309) and a secondary receiving portion (307) capable of accommodating at least one primary conversion device (308) and at least one secondary conversion device (306) respectively. The primary receiving portion (309) is disposed at a downstream end portion of the discharge pipe (305). The secondary receiving portion (307) is disposed at an upstream of the primary receiving portion (309). The present subject matter provides minimal back pressure and at the same optimal functioning of the conversion device with long life of the conversion device.

La présente invention concerne un moteur thermique (141) pour un véhicule motorisé (101). Un système d'échappement (300) comprend une partie de réception primaire (309) et une partie de réception secondaire (307) aptes à recevoir respectivement au moins un dispositif de conversion primaire (308) et au moins un dispositif de conversion secondaire (306). La partie de réception primaire (309) est disposée dans une partie d'extrémité aval du tuyau d'évacuation (305). La partie de réception secondaire (307) est disposée en amont de la partie de réception primaire (309). Le moteur selon l'invention fournit une contre-pression minimale tout en assurant le même fonctionnement optimal du dispositif de conversion avec une longue durée de vie du dispositif de conversion.
