Method for operating oxygen sensor arrangement in exhaust gas system of internal combustion engine, involves detecting values for diagnosis of active oxygen adjustment, where former value represents oxygen storage capacity of catalyst
Method for operating oxygen sensor arrangement in exhaust gas system of internal combustion engine, involves detecting values for diagnosis of active oxygen adjustment, where former value represents oxygen storage capacity of catalyst
The method involves detecting the values for the diagnosis of active oxygen adjustment, where the former value represents the oxygen storage capacity of a catalyst (12), and the latter value represents the oxygen discharge capacity of the catalyst. A characteristic offset of an oxygen sensor (18) is calculated from the ratio of oxygen storage capacity to oxygen discharge capacity. An adaption of the characteristic offset takes place with a natural frequency control of the catalyst. Independent claims are included for the following: (1) a computer program for executing a method for operating an oxygen sensor arrangement; and (2) a computer program product for executing a method for operating an oxygen sensor arrangement.
