SENSITIVITY OF THE ZIRCONIA OXYGEN SENSOR TO TEMPERATURE AND FLOW RATE OF EXHAUST GAS

The zirconia oxygen sensor provides a feedback signal for stoichiometric air-fuel ratio (A/F) control of an engine. The present investigation was undertaken to quantify factors affecting sensor accuracy. Coefficients for the differential changes in sensor voltage due to changes of engine air-fuel ratio, exhaust flow, and exhaust temperature were determined. /GMRL/
