ABSTRACT:
The invention is directed to a method for evaluating the operability of a catalytic converter mounted in the exhaust-gas system of an internal combustion engine. In the method, the actual value of a signal of an exhaust-gas probe mounted downstream of the catalytic converter is detected and an expectation value of the signal of the exhaust-gas probe is formed from quantities measured upstream of the catalytic converter. A measure is formed for the deviation of the actual value from the expectation value and the operability of the catalytic converter is evaluated on the basis of the measure.
