The way how the Air/Fuel mixture controller is calibrated impacts directly the performance of catalytic converters.
Due to the transport phenomena and feedback time constants involved, Air/Fuel ratio cannot be held static at its value of stoichiometric equilibrium. The frequency and amplitude of the resulting oscillation can be manipulated to achieve the maximum possible steady state catalytic removal efficiency.
In this study, specific effects of each Lambda controller parameter are investigated, and used to determine the optimum calibration setting that results in the highest removal efficiency.
