Claims (5)
- REVENDICATIONS1. Procédé de contrôle d'un système de traitement des gaz d'échappement présents dans une ligne d'échappement d'un moteur à combustion interne, ledit traitement impliquant l'injection par un module jauge-pompe d'un agent réducteur dans la ligne d'échappement, cette injection étant pilotée par un module de calcul apte à déterminer la quantité d'agent réducteur idoine à injecter, caractérisé en ce que l'opération du module de contrôle est subordonnée à un superviseur n'autorisant une injection que si la pression ambiante est supérieure à une pression donnée, la température extérieure est dans une plage de température donnée et le module jauge-pompe est jugé opérationnel.
- 2. Procédé selon la revendication 1, caractérisé en ce que la plage de température pour laquelle une injection peut être autorisée est comprise entre -30°C et +80°C.
- 3. Procédé selon la revendication 1 ou la revendication 2, caractérisé en ce que la pression ambiante minimale pour autoriser une injection est de 800 HPa.
- 4. Procédé selon l'une quelconque des revendications précédentes, caractérisé en ce que le module jauge-pompe est jugé opérationnel s'il est placé dans un des états de fonctionnement suivants : injection en boucle ouverte, injection avec adaptation en boucle fermée ou injection avec régulation de la consommation du réducteur.
- 5. Procédé selon la revendication 4, caractérisé en ce que le module jauge-pompe est exclusivement dans un des états suivants, classés par ordre prioritaire : injection inhibée, injection avec régulation de la consommation de réducteur, injection avec adaptation en boucle fermée et injection en boucle ouverte.
