Abstract
La présente invention concerne un procédé et un appareil pour mesurer les émissions du flux d'échappement d'un dispositif d'assainissement catalytique visant à déterminer l'efficacité d'évacuation d'un gaz de traitement. Le procédé consiste à fournir un capteur étalonné servant à mesurer une gamme sélectionnée de la concentration de gaz de traitement dans le dispositif d'assainissement catalytique à partir d'un flux d'échappement une fois que le gaz de traitement aura été traité pour vérifier l'efficacité du dispositif d'assainissement catalytique et la sortie ou la commande du dispositif d'assainissement sur la base des valeurs d'efficacité générées.
