Abstract: For continuous and accurate monitoring of the conversion rate of an exhaust catalyst during operation of an internal combustion engine, temperature values are determined at two measuring points upstream and downstream of the catalyst in the direction of exhaust gas flow. In order to obtain an evaluatable signal difference at all times, at least one of the measured exhaust gas temperature values is filtered so that the temperature value obtained assures a reliable temperature difference with respect to the other temperature value at all times. The actual temperature difference value obtained in this way is compared with a desired temperature difference value generated by a three-dimensional desired value characteristic map and is checked with the aid of a plausibility check.
