ABSTRACT:
A method for monitoring the conversion capacity of a catalytic converter assesses a conversion capacity of a preliminary catalytic converter by calculating thermal energy generated in a reference catalytic converter that is not catalytically coated in accordance with a temperature model and making a comparison with a measured thermal energy generated in the preliminary catalytic converter. A measure of the conversion capacity of the preliminary catalytic converter is ascertained from the difference, and it is compared with a comparison value. The preliminary catalytic converter has an adequate conversion capacity if the difference is above the comparison value.
