(FR) APPAREIL, VÉHICULE ET PROCÉDÉ
Abstract
(EN)
An apparatus is provided for the catalytic treatment of exhaust gas from an internal combustion engine comprising: a. a casing having an exhaust gas inlet and a treated exhaust gas outlet; b. a heater disposed within the casing, through which exhaust gas may flow; and c. a catalyst article disposed within the casing adjacent to the heater, through which exhaust gas can flow; wherein the heater comprises an electrically resistive wire mounted on an electrically insulating frame.
(FR)
L'invention concerne un appareil pour le traitement catalytique de gaz d'échappement provenant d'un moteur à combustion interne, comprenant : a. un boîtier ayant une entrée de gaz d'échappement et une sortie de gaz d'échappement traités; b. un dispositif de chauffage disposé à l'intérieur du boîtier, à travers lequel un gaz d'échappement peut s'écouler; et c. un article catalyseur disposé à l'intérieur du boîtier de manière adjacente au dispositif de chauffage, à travers lequel un gaz d'échappement peut s'écouler; le dispositif de chauffage comprenant un fil électriquement résistif monté sur un cadre électriquement isolant.
