摘要： A method for operating a particulate filter situated in an exhaust gas area of an internal combustion engine and a device for carrying out the method are described. A measure of the particulate matter burn-off rate is detected for influencing and/or monitoring the particulate matter burn-off rate or for influencing and/or monitoring the particulate filter temperature. A secondary air flow supplied by a secondary air pump is blown into the exhaust gas area upstream from the particulate filter. The secondary air flow is determined as a function of the detected measure of the particulate matter burn-off rate. If necessary, the secondary air flow may be enriched by an oxygen flow or nitrogen flow supplied by an air separation unit. The method prevents the particulate filter from being damaged by an unacceptably high particulate matter burn-off rate or an unacceptably high particulate filter temperature.

摘要： A method of reducing NO.sub.x emissions of a turbo-charged internal combustion engine. The engine has an exhaust conduit guiding an exhaust gas stream, a charge-air intake conduit guiding a charge-air stream and a turbocharger including a turbine disposed in the exhaust conduit and a compressor disposed in the charge-air intake conduit. The method comprises the steps of branching off a partial exhaust gas quantity from the exhaust gas stream upstream of the turbine as viewed in a direction of exhaust gas flow; passing the partial exhaust gas quantity through a particle filter; and introducing the partial exhaust gas quantity into the charge-air stream upstream of the compressor.
