Mixture Strength in Petrol Engines Continuously Controlled by Electric Exhaust Gas Analysers

Published online by Cambridge University Press:  28 July 2016

Extract

During the last few years continuous indicating electric exhaust gas analysers have been coming into use more and more for controlling the strength of the fuel/air mixture which the carburettor feeds into the engine.

These instruments have already been described in a publication (vide List of References (i)), but since they are of growing interest, especially for aviation, some further research as to their merits and shortcomings seems to be indicated.

Therefore tests have been run with an aircraft type of instrument (the “ Cambridge (N.Y.) Aero Mixture Indicator ”) and an automobile type of instrument (the “ Lantz Phelps Motor Fuel Combustion Tester ” ).
