Title (EN) FLOW DEVICE FOR AN EXHAUST SYSTEM
(FR) DISPOSITIF D'ÉCOULEMENT POUR SYSTÈME D'ÉCHAPPEMENT
Abstract:
(EN) A flow device for an exhaust system includes a body that defines an interior cavity. An exhaust inlet passage (53) is disposed in the interior cavity. An exhaust outlet passage (55) is disposed in the interior cavity so that at least a portion of the exhaust inlet passage (53) circumferentially surrounds at least a portion of the exhaust outlet passage (55). A doser (25) is adapted to inject reductants into the interior cavity of the body such that the reductants are injected in the same general direction as the direction of flow of the exhaust gases.
(FR) L'invention porte sur un dispositif d'écoulement pour un système d'échappement, lequel dispositif d'écoulement comprend un corps qui définit une cavité intérieure. Un passage d'entrée d'échappement (53) est disposé dans la cavité intérieure. Un passage de sortie d'échappement (55) est disposé dans la cavité intérieure de telle sorte qu'au moins une partie du passage d'entrée d'échappement (53) entoure de manière périphérique au moins une partie du passage de sortie d'échappement (55). Un doseur (25) est apte à injecter des réducteurs dans la cavité intérieure du corps de telle sorte que les réducteurs sont injectés dans la même direction globale que la direction d'écoulement des gaz d'échappement.
