ABSTRACT:
In a gas analysis method and apparatus especially suitable for controlling the inlet air to fuel ratio of a lean-running internal combustion engine, combustion effluent gas is divided into a plurality of part streams, there is added to a first part stream whichever of a combustible and a combustion-supporting constituent it is deficient in, combustion is effected and the temperature difference between the streams is measured. Preferably the temperature difference is measured by reference to the magnitude of the electric current required to heat an untreated part stream to the temperature of a part stream heated by combustion due to the added constituent. Preferably the temperature sensor used acts as a catalyst for the combustion and as a heating element, so that combustion takes place only in the vicinity thereof. Gas flow through the apparatus is preferably effected by a constant vacuum engine intake.
