    摘要： A method of operating components for exhaust gas after-treatment disposed in the exhaust gas tract of a turbocharged internal combustion engine. A partial exhaust gas stream is removed from the main exhaust gas stream upstream of at least one exhaust gas turbine. The partial exhaust gas stream is fed back into the main exhaust gas stream downstream of the at least one exhaust gas turbine. The feed is located, in terms of exhaust flow, between an NO oxidation catalytic converter and a particle filter (i.e., the exhaust gas after-treatment component). That is, the at least one exhaust gas after-treatment component is arranged downstream of the feed. The quantity of exhaust gas branched off as a partial exhaust gas stream is controlled or closed-loop controlled as a function of at least one target temperature in at least one defined point in the exhaust gas tract, in particular in the partial exhaust gas stream and/or of the at least one exhaust gas after-treatment component.

    摘要： A method and to a device for the regeneration of a particle filter arranged in the exhaust gas tract of an internal combustion engine with at least one NO oxidation catalyst for the oxidation of NO, especially to NO2, which is arranged upstream of the particle filter and through which an exhaust gas stream flows. At least one heater, especially a heating catalyst, through which another gas stream, i.e., a second exhaust gas stream, flows and which heats the additional gas steam, is provided upstream of the particle filter. The heated additional gas stream is mixed upstream of the particle filter with the exhaust gas stream coming from the NO oxidation catalyst, i.e., the gas stream loaded in particular with NO2.
