Abstract
A method for detecting the aging of a heterogeneous catalytic converter, including the following steps: acquiring at least one measurement signal in a media flow passing through the catalytic converter downstream of the catalytic converter; applying a time-variant input signal to the media flow and/or the catalytic converter; evaluating a behavior of the at least one measurement signal as a function of the time-variant input signal; and detecting a state of aging of the catalytic converter.
