Abstract (en)
[origin: DE10206399C1] The forced stimulation method has 2 different weak/rich amplitude values superimposed on the lambda required value during successive sets of exhaust packets, the regulation device determining the second amplitude value and a component of the second exhaust packet set, so that the signal values provided by the lambda probe on the downstream side of the catalyzer are altered.
