Control method for motor vehicle emissions control has threshold value dependent on service life of filter to form control parameter for emissions system

摘要

The control method for motor vehicle internal combustion engine (100) emissions control (115) has a special operating condition which operates when a set operating parameter threshold value is exceeded. The threshold value can be dependent on a characteristic involving the service life of the emissions system. The threshold value can be dependent on a sensed or control parameter. Claims include an apparatus for carrying out the method.
