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 streams, there is added at 24 to a first stream a combustible and/or a combustion-supporting constituent it is deficient in, combustion is effected of the first and another stream and the temperature difference between the streams is measured using platinum or the like wires 30A, 30B. Preferably the temperature difference is measured by reference to the magnitude of the electric current required to heat an untreated stream to the temperature of a stream heated by combustion due to the added constituent. A gas equilibration process in a chamber 16 may be effected before the streaming of the gas. The wires 30A, 30B are mounted in different Wheatstone bridges, the outputs thereof being compared to determine the temperature difference (Figure 3, not shown). Gas flow through the apparatus is preferably effected by a constant vacuum engine intake. <IMAGE>
