Title
(EN) EXHAUST TRAIN COMPRISING A PHOTOACOUSTIC SENSOR FOR MEASURING AT LEAST ONE CONCENTRATION OF POLLUTING GAS, AND MOTOR VEHICLE COMPRISING SUCH AN EXHAUST TRAIN
(FR) LIGNE D'ÉCHAPPEMENT COMPRENANT UN CAPTEUR PHOTOACOUSTIQUE POUR MESURER AU MOINS UNE CONCENTRATION EN GAZ POLLUANT ET VÉHICULE AUTOMOBILE COMPRENANT UNE TELLE LIGNE D'ÉCHAPPEMENT
Abstract
(EN)
The invention relates to an exhaust train (14) for an internal combustion engine, comprising a conduit (20) for circulating an exhaust gas stream, and at least one measuring member (30) for measuring at least one pollutant gas concentration in the exhaust gas stream circulating in said conduit (20). The measuring member (30) comprises a photoacoustic sensor (32).
(FR)
Cette ligne d'échappement (14) pour moteur à combustion interne comprend une conduite (20) de circulation d'un flux de gaz d'échappement et au moins un organe de mesure (30) pour mesurer au moins une concentration en gaz polluant du flux de gaz d'échappement circulant dans ladite conduite (20). Cet organe de mesure (30) comprend un capteur photoacoustique (32).
