Abstract

Even though the zirconia-oxygen sensor serves as the primary feedback sensor in current production fuel-air ratio control architectures, there has been no work investigating the use of the one-bit output of this sensor to identify spark-ignition engine system parameters. In this research, we present experimental and simulation data that show portions of the important engine dynamics can be determined with this nonlinear sensor using a new identification algorithm proposed in the paper. Comparisons will be made between using the zirconia-oxygen and a linear sensor for this purpose
