A device model was developed which permits one to derive directly from voltage vs air-fuel ratio curves the physical constants of real sensors. In all the following cases, use of the derived physical constants gave computed curves which closely matched the experimental curves. The computed curves, therefore, can be used to mathematically simulate the behavior of actual sensors. The model was applied to three different cases of experimental interest: same sensor operated at various exhaust temperatures; same sensor with and without electrode overcoating; and same sensor operated with different directions of air-fuel ratio change.
