The valve cone support is provided at a distance from the valve disk (7).

Abstract: 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.

Abstract: In a method and apparatus for the longitudinal and lateral guidance assistance to the driver of a vehicle, longitudinal guidance assistance is performed as distance regulation for regulating the distance between the vehicle and a preceding guide vehicle. Lateral guidance assistance is optionally carried out as an object tracking regulation for guiding the vehicle according to a displacement lane of a preceding guide vehicle, as a lane tracking regulation for guiding the vehicle along a marked driving lane, or as combined lane object tracking regulation. The lateral guidance assistance is then available only when the distance regulation is active and when the distance between the vehicle and the guide vehicle is smaller than a predefined distance limit and/or when a shaft angle as a viewing angle from the vehicle to the guide vehicle is smaller than a predefined angle limit.
