Abstract (en)
[origin: EP1074718A2] The method involves detecting a measurement signal for the lambda probe (18, 20), determining a demand signal for the lambda probe using a model of the engine (12) and deriving a monitoring value from the ratio of measurement signal to demand signal for comparison with a defined threshold value
