Abstract
Dans une première unité de traitement on stocke préliminairement une certaine quantité d'oxydes d'azote contenue dans des gaz d'échappement de combustion en fonction d'une valeur numérique représentant une quantité de combustion. Dans une seconde unité de traitement, on stocke préliminairement un mélange d'ammoniac et d'oxydes d'azote selon un certain rapport, en fonction de la température des gaz d'échappement de combustion. Une valeur numérique observée représentant la quantité de combustion est envoyée dans la première unité de traitement pour déterminer la quantité d'oxydes d'azote dans le gaz d'échappement de combustion. La température observée des gaz d'échappement de combustion est envoyée dans la seconde unité de traitement pour déterminer le rapport du mélange << ammoniac et oxydes d'azote >>. La quantité optimale d'injection de l'ammoniac est obtenue en multipliant la quantité des oxydes d'azote obtenue au moyen de la première unité de traitement par le rapport entre l'ammoniac et les oxydes d'azote obtenu au moyen de la seconde unité de traitement
