CHARACTERIZATION OF ZIRCONIA AND TITANIA ENGINE EXHAUST GAS SENSORS FOR AIR/FUEL FEEDBACK CONTROL SYSTEMS

Two types of exhaust sensors have been studied from the point of view of applying them in feedback systems to control the air/fuel (A/F) operating point of automotive engines. The particular sensors studied were zirconia sensors and titania sensors. The paper includes results obtained from engine dynamometers and test vehicles/ but the major experimental results are from laboratory tests specifically designed to establish advantages or limitations of a specific sensor and its associated circuitry when used in engine A/F control systems. /GMRL/
