    摘要: The invention relates to an exhaust gas aftertreatment device for an internal combustion engine supercharged in two stages, having an oxidation catalyst, a particle filter, and a metering device for introducing a regeneration agent into an exhaust gas system, and to an associated method for exhaust gas aftertreatment. According to the invention, the metering device is arranged in the exhaust gas system between a high-pressure turbine and a low-pressure turbine which produce two-stage supercharging of the internal combustion engine.

    摘要: A procedure for the operation of an internal combustion engine is disclosed, in whose exhaust gas area a particle filter is arranged which is freed from the stored particles during a regeneration. A measure for a load of the combustion engine is compared to a load threshold value. An overrun cut-off, at which the fuel metering is completely suppressed, is carried out if the measure for the load falls below the load threshold value and if the engine speed of the combustion engine lies above an engine speed threshold value. The load threshold value that has been determined to a value higher than zero is further dependant on the particle filter's regeneration signal. The procedure aims to prevent the overheating of the particle filter during its regeneration.
