CATALYTIC CONVERTER FUNCTION DETECTION
A method and system detects the function of a catalytic converter in a vehicle using data received from an open path emissions sensor. The factors considered include whether the vehicle moving on a road is operating in a closed loop operating condition, whether the vehicle is operating in a cold sta...

| description | A method and system detects the function of a catalytic converter in a vehicle using data received from an open path emissions sensor. The factors considered include whether the vehicle moving on a road is operating in a closed loop operating condition, whether the vehicle is operating in a cold start mode, and the hydrocarbon and other tailpipe emissions concentrations in an exhaust stream of the vehicle as measured by the open path sensor.
L'invention concerne un procédé et un système permettant de déterminer le bon fonctionnement d'un convertisseur catalytique d'un véhicule à partir de données transmises par un capteur d'émissions en circuit ouvert. Ce procédé consiste, d'une part, à déterminer si le véhicule qui se déplace sur la chaussée fonctionne dans un état de fonctionnement en boucle fermée ou s'il fonctionne en mode de démarrage à froid et, d'autre part, à mesurer, à l'aide du capteur en circuit ouvert, les teneurs en hydrocarbures et autres gaz d'échappement du flux d'émission du véhicule. |
