A method for monitoring pollutant emissions during the operation of a combustion engine and/or an exhaust-aftertreatment device in a motor vehicle includes determining one or more pollutant-limit values for one or more pollutant categories using an emission limit-value model and as a function of one or more operating-state variables of the motor vehicle; ascertaining a pollutant-concentration variable for each pollutant category using sensors; and detecting an error in the form of an exceeding of the one or the plurality of pollutant-limit vales as a function of the pollutant-concentration variable for each pollutant category.

Method and device for emission monitoring of a combustion engine in a motor vehicle

Described is a method for operating an internal combustion engine (), in which method at least one parameter of the exhaust gas flowing in an exhaust-gas duct () is detected by at least one exhaust-gas probe (), wherein the internal combustion engine () is at least temporarily turned over by a starting device (), during which an injection and combustion of fuel does not take place, and during and/or after which the exhaust-gas probe () is adjusted.
