Abstract

The invention relates to a device for the regeneration, temperature loading and/or thermal management of a component, which is assigned to an exhaust gas system, of an internal combustion engine preferably of a vehicle, having at least one injection valve, which operates preferably in a chatter mode as a function of the pressure of supplied fuel, for injecting fuel for the purpose of regeneration, temperature loading and/or thermal management into the exhaust system of the internal combustion engine. The invention is distinguished by at least one pressure control valve which is arranged upstream of the injection valve and dampens or eliminates pressure fluctuations. The invention also relates to a corresponding method.
