- the invention relates to a method and apparatus for operating an internal combustion engine with a arranged in an exhaust tract of the internal combustion engine upstream of or in a Abgaska ⁇ talysator exhaust gas probe whose measurement signal is characteristic of a residual oxygen content of the flowing past their exhaust gas.
- On-Board Diagnostic So far, the focus on on-board diagnostics has been on symmetrically aged probes, that is, the dynamics of the fat-lean and lean-fat direction have not differed significantly.
- Recent OBD regulations now also require detection of asymmetrically aged exhaust gas probes. Here it is assumed that the dynamics deterioration acts only in one direction, while the other direction still has a nominal behavior.
- ge ⁇ aged exhaust gas probe results in a significant deterioration in the emissions due to a central position of displacement of the mixture. This is based on differences between ge ⁇ messengerem and the expected course of the air ratio during the forced excitation. The lambda control then reacts and shifts the mixture middle position according to the asymmetry.

- the invention is characterized by a method and a corresponding apparatus for operating an internal combustion engine with an exhaust gas probe arranged in the exhaust tract of the internal combustion engine or in an exhaust gas catalytic converter, the measurement signal of which is characteristic for a residual oxygen content of the exhaust gas flowing past it.
- Forced excitation is given a third measurement time duration and a minimum value of the air ratio, represented by the measurement signal of the exhaust gas probe, determined as a function of the signal variation of the measurement signal of the exhaust gas probe during the third measurement period as the first minimum value.
