TEMPERATURE SENSITIVITY MAPPING OF THE ZIRCONIA OXYGEN SENSOR: ENGINE TEST RESULTS

Temperature sensitivity of the oxygen sensor was measured over a wide range of engine operating conditions. Sensor data were plotted in the form of contour lines of constant sensor voltage as a function of engine air-fuel ratio and exhaust temperature, thereby mapping sensor performance. It was found that, depending on the sensor, a fixed level of sensor voltage shifted from 0.1 to 0.7 ratios towards air-fuel ratios slightly rich of the stoichiometric ratio as exhaust temperature incrased from 500 degrees C to 700 degrees C. /GMRL/
