Summary

We used transfer function approach to investigate exhaust oxygen sensor dynamics in engine exhaust environment. All the sensor dynamic mechanisms were identified. They are attributed to the effect of individual component of the sensor, such as the louver-shield, the protection coating-layer, and the sensing electrode; the gas transport system, such as the exhaust pipe gas blending effect; the exhaust generation system, such as the engine liquid fuel wall wetting, and the discrete individual cylinder event.
