ABSTRACT:
An exhaust catalyst is charged with oxygen until saturated. A given first rich air/fuel ratio is set in a combustion chamber of a cylinder. A first oxygen storage capacity value is determined depending on the measured signals from first and second exhaust probes. The exhaust catalyst is charged with oxygen until saturated. A given second rich air/fuel ratio is set in the combustion chamber of the cylinder. A second oxygen storage capacity value is determined depending on the measured signal from the first and second exhaust probe. A corrected oxygen storage capacity value is determined depending on the first and second oxygen storage capacity values.
