Abstract

L'invention propose un procédé de régulation de la richesse du mélange carburant/air d'alimentation d'un moteur à combustion d'un véhicule automobile dont ia ligne d'échappement est équipée d'un dispositif de traitement des gaz d'échappement, pour minimiser la production de substances polluantes, telles que des hydrocarbures, du monoxyde de carbone, du type dans lequel la quantité de carburant injectée (Q) dépend notamment d'un terme proportionnel (Bprop) et d'un terme intégral (Bint) qui sont déterminés notamment à partir de la pression régnant dans le collecteur d'admission et du régime du moteur, caractérisé en ce que lors d'une phase particulière de fonctionnement du moteur qui provoque une variation de la richesse du mélange, le terme proportionnel (Bprop) et le terme intégral (Bint) sont multipliés par un premier et un second coefficients (D1, D2) respectivement qui sont supérieurs ou égaux à 1, de façon à accélérer le retour à la richesse stoechiométrique et à minimiser la production de substances polluantes.
