Patent ID: 8256209

Claim:
A device for regeneration, temperature loading and/or thermal management of a component, associated with an exhaust system, of an internal combustion engine, the device comprising: at least one injection valve operating in chatter mode as a function of the pressure of supplied fuel, for injecting fuel into the exhaust system of the engine for the regeneration, temperature loading, and/or thermal management of the component; at least one pressure control valve disposed upstream of the injection valve, the pressure control valve operable to damp or eliminate pressure fluctuations, the device being connected to a low-pressure circuit that carries fuel under low pressure to a fuel injection system of the internal combustion engine which has a high-pressure circuit to enable injecting fuel into cylinders of the internal combustion engine; and a stabilizing volume disposed in a low-pressure region of the fuel injection system and being connected upstream of the pressure control valve.
