Process for desulfurizing a nitrogen oxide trap in the exhaust system of a combustion engine |
| abstract |
The invention relates to a fuel-saving method for desulfurization of a nitrogen oxide trap in the exhaust system of an internal combustion engine with devices for influencing the temperature of the nitrogen oxide trap and for influencing the air / fuel ratio of the mixture supplied to the internal combustion engine. The current SO x uptake rate is determined on the basis of a functional relationship and integrated in time. When a threshold value is exceeded, a desulfurization cycle is initiated, during which the nitrogen oxide trap is brought to a predetermined temperature for a predetermined time and the internal combustion engine is operated with a predetermined air / fuel ratio during this time. The temperature is changed by changing the ignition point in the "late" direction and by means of a variable exhaust system. |
