Abstract

This improvement on functions and performances of exhaust gas sensor should be indispensable to qualify the emission regulation of ULEV. The tubular zirconia cell with limited diffusion layer laminated platinum foil heater on it have been prepared for sensor. The electronic module mainly consists of an ASIC and a single-chip micro-computer. By time shared (4msec) feed back control for constant electromotive force (0.5V) and constant cell temperature (700°C), it have been achieved frequency response (20Hz), warm-up time (5sec) and required on board durability.
