  • Method of monitoring an exhaust gas aftertreatment system
    Patent number: 10240502
    Abstract: The subject matter of the disclosure relates to a method of diagnosing NOx storage catalyst during the operation of a motor vehicle. The method uses two diagnosis sub-methods having various sensitivities with respect to sulfur contamination of the NOx storage catalyst. The results of the two sub-methods are used to ascertain proportions of aging of the NOx storage catalyst resulting from thermal aging and sulfur contamination.
