Abstract

Appareil destiné à engendrer un signal électrique en fonction de la pression partielle de l'oxygène présent dans les gaz d'échappement d un moteur à combustion interne. Appareil dans lequel un disque en électrolyte solide a l'une de ses faces revêtue d'une électrode catalytique et l'autre de ses faces revêtue d'une électrode non catalytique, ce disque étant monté sur chant dans le flux des gaz d'échappement de manière que ses deux électrodes soient plongées l'une et l'autre dans les gaz d'échappement. Appareil applicable aux dispositifs de surveillance des gaz d'échappement pour moteurs d'automobiles.Apparatus intended to generate an electrical signal as a function of the partial pressure of oxygen present in the exhaust gases of an internal combustion engine. Apparatus in which a solid electrolyte disc has one of its faces coated with a catalytic electrode and the other of its faces coated with a non-catalytic electrode, this disc being mounted on edge in the flow of exhaust gases so that its two electrodes are both immersed in the exhaust gases. Apparatus applicable to exhaust gas monitoring devices for automobile engines.
