Abstract

Cette invention concerne un procédé et un appareil pour l'analyse de gaz. Un gaz de combustion formant effluent est divisé en plusieurs courants partiels et on ajoute à un premier courant partiel un combustible ou un constituant entretenant la combustion, selon celui qui fait défaut, on provoque la combustion et on mesure la différence de température entre les courants. Ce procédé et cet appareil sont utilisables notamment pour contrôler le rapport air/carburant à l'entrée d'un moteur à combustion interne travaillant avec un mélange << pauvre >>.
