Definitions
- FIG. 2 shows a schematic diagram of the NOx emissions at the outlet of the catalyst dr
- the storage catalyst of the catalyst 12 is loaded with nitrogen oxides during shift operation. In a subsequent homogeneous drive, the storage catalytic converter is discharged again and the nitrogen oxide is reduced by the three-way catalytic converter.
- the storage catalyst takes up sulfur over time during its continuous loading and unloading with nitrogen oxides. This leads to a limitation of the storage capacity of the catalyst, which is referred to below as aging.
