Method for operating a three-way catalyst of an internal combustion engine |
| 摘要 |
An internal combustion engine (1), especially for a motor vehicle, is described, which has a three-way catalytic converter (12'') and a storage catalytic converter (12') which can be loaded with and unloaded of nitrogen oxides. A diagnosis of the storage catalytic converter (12') is carried out by a control apparatus (18) below a temperature at which the three-way catalytic converter (12'') does not yet operate.
