Beschreibung
Zusammenfassung:	The invention relates to a device for the regeneration, temperature loading and/or thermal management of a component, assigned to an exhaust system, of an internal combustion engine. The device includes at least one injection valve which injects a fluid, in particular fuel, into the exhaust system, preferably in chatter mode, for example as a function of the pressure of the supplied fluid. The injection valve has a valve head and a valve seat which have geometries designed in such a way that a fluidic force of the supplied fluid acting on the injection valve drops continuously over a stroke of the valve head. The invention also relates to an injection valve having such valve-head and valve-seat geometries and to a corresponding method for the regeneration, temperature loading and/or thermal management of a component, assigned to an exhaust system, of an internal combustion engine.
