Abstract

a. Circuit de surveillance de la composition des gaz d'échappement de moteur à combustion interne. b. Circuit de surveillance caractérisé en ce qu'il est prévu un deuxième détecteur réagissant à la concentration en oxygène, dont la conductibilité se modifie proportionnellement à la concentration en oxygène, et en ce qu'il est prévu, pour la production de signaux d'alerte et/ou de régulation, un circuit de signalisation commandé en fonction de la conductibilité du deuxième détecteur. c. L'invention s'applique notamment aux moteurs d'automobiles.
