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.

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 catalytic motor vehicle radiator for cooling a coolant flowing through it has a catalytically acting surface for converting a pollutant into an environmentally compatible material, a temperature sensor for sensing a coolant temperature, and an attachment point for attaching the temperature sensor. The temperature sensor has an attachment for attaching the temperature sensor to the attachment point of the catalytic motor vehicle radiator, and includes an electrical identification unit for identifying the catalytic motor vehicle radiator. The attachment interacts with an attachment point of the catalytic motor vehicle radiator in such a way that, if the temperature sensor is removed from the catalytic motor vehicle radiator, the temperature sensor is destroyed.
