Abstract
This paper describes the design and operation of multi-layered zirconia oxygen sensor for variable air-fuel ratio controlled engine.
A compact and rigid sensor chip consisting of two electrochemical cells; pumping cell and sensing cell, and heater has been developed utilizing laminating and co-firing technology. Air-fuel ratio 10 to 25 can be covered by changing the polarity of pumping current. Effect of exhaust gas temperature on air-fuel ratio output signal is small enough to eliminate temperature compensation. No significant deterioration is observed after 50,000 equivalent miles of engine dynamometer testing.
