Summary

The area of lean and lean-stoichiometric-rich A/F sensors based on oxygen pumping with ZrO2 electrochemical cells is reviewed. First, the principles of oxygen pumping and its application to A/F sensing are explained. The general properties of this type of A/F sensors are then described and the advantages of O2-pumping-based sensors over resistive and potentiometric type A/F sensors are discussed. Finally, the various sensor designs developed to date are described and their performance characteristics are analyzed and compared.
