NON-IDEAL PROPERTIES OF ZRO2 AND TIO2 EXHAUST GAS OXYGEN SENSORS

A brief description of ZrO2 and TiO2 exhaust gas oxygen sensors is presented, followed by a comparison of the two sensors operating under actual open-loop and closed-loop conditions on an engine/dynamometer setup. The sensitivity of the ZrO2 sensor to engine load and cyclinder-to-cyclinder maldistribution is explored, and the compatibility of the ZrO2 switch point and a three-way catalyst window is considered.
