Abstract

Procédé de génération, de manière contrôlée, d'une dégradation accélérée de l'efficacité de traitement d'émissions polluantes d'un catalyseur d'oxydation-réduction formé par des blocs monolithiques par balayage de chambre en mélange riche jusqu'à atteindre une valeur de seuil de température interne du catalyseur sur un moteur à allumage commandé.Method of generating, in a controlled manner, an accelerated degradation of the treatment efficiency of polluting emissions of an oxidation-reduction catalyst formed by monolithic blocks by sweeping a chamber in a rich mixture until a value is reached internal temperature threshold of the catalyst on a positive-ignition engine.
