Method for stimulating a lambda control loop

The forced stimulation method has a forced stimulation with at least one frequency and amplitude superimposed on the lambda required value, for providing weak and rich sections, the amplitude and/or frequency of the forced stimulation dependent on the operating temperature of the IC engine (10), e.g...

Zusammenfassung:The forced stimulation method has a forced stimulation with at least one frequency and amplitude superimposed on the lambda required value, for providing weak and rich sections, the amplitude and/or frequency of the forced stimulation dependent on the operating temperature of the IC engine (10), e.g. the IC engine coolant temperature.
