摘要： The invention relates to In an operating and diagnostic method for an SCR exhaust gas aftertreatment system which has an SCR catalytic converter with ammonia storage capacity, a signal of an exhaust gas sensor that is sensitive to nitrogen oxide and ammonia and is arranged downstream of the SCR catalytic converter, is measured. In a normal operating mode, ammonia is supplied to the SCR catalytic converter corresponding to a filling level model for ammonia stored in the SCR catalytic converter, in such a way that the ammonia filling level of the SCR catalytic converter is held at least approximately at a predefinable nominal value (or value range). The normal operating mode is interrupted if an exhaust gas sensor signal that exceeds a predefinable first limit value, is registered, and the set urea dosing rate is increased by a predefinable degree in relation to the value provided in the normal operating mode. Thereafter, a return is made to the normal operating mode, or a switch is made to a diagnostic operating mode, as a function of the profile of the signal of the exhaust gas sensor.

摘要： A method and apparatus for detecting the presence of a prescribed heat exchanger, such as a catalytically active radiator, in a motor vehicle are performed, during operation of the motor vehicle. The temperature of a heat-exchanger medium is observed together with further current operationally relevant parameters of the motor vehicle for a prespecified time window. An expected temperature gradient over time of the heat-exchanger medium is detected, as well as the current temperature gradient over time of the temperature of the heat-exchanger medium. The presence of a prescribed heat exchanger is detected taking into account the expected temperature gradient and the current temperature gradient.
