Abstract

L'invention concerne un dispositif de contrôle du rapport air/carburant pour détecter la composition et la concentration des gaz à l'échappement d'un moteur. Selon l'invention, il comprend un moyen 10 pour commuter un courant externe d'alimentation vers le capteur 3 des gaz d'échappement, un moyen 9 pour établir au préalable une valeur intermédiaire entre une valeur V''x de la tension de sortie du capteur à laquelle on peut s'attendre quand le mélange gazeux est trop riche et une valeur V''y quand il est trop faible. L'invention s'applique notamment à l'industrie automobile
