Abstract

Système pour contrôler la recirculation des gaz d'échappement dans un moteur à combustion interne comportant des moyens d'alimentation en carburant commandés par une unité électronique de contrôle. Un capteur détermine si le mélange air-carburant des gaz d'échappement est en dessous ou au-dessus des conditions stoechiométriques pour engendrer un signal de réaction vers l'unité électronique de contrôle de maniere à tendre vers les conditions stoechiométriques. La recirculation des gaz d'échappement est commandée par une valve sensible à un signal de commande Le signal de commande est égal à la somme d'un premier signal sensiblement égal au signal de commande délivré par un programmateur plus un signal de correction, et un second signal impulsionnel ayant une fréquence déterminée. Le signal de correction est fonction de l'amplitude de la composante du signal de réaction ayant la fréquence prédéterminée.
