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.

摘要： A filter system for removing particulates from exhaust gases of an internal combustion engine, in particular a diesel engine, having at least one filter member formed by filter channels in the configuration of a honeycomb and made of a porous filter material, in which the region of the inlet openings of the filter channels open on the gas intake side, electrical resistance looped heating elements are arranged that are connected via a lead-in and a lead-out to a power supply. A secure positioning of the heating loops in the honeycomb is assured and contact errors are avoided. The loops of the resistance heating elements and/or the loop connections are received in grooves of the filter system in such a manner that they retain their pre-determined position despite vibrations, thermally-induced shape changes and the like. The grooves can be located in the filter member and/or in a cover plate overlying the inlet face of the filter member.

摘要： In an operating method for internal combustion engines which operate with exhaust-gas aftertreatment systems, in particular diesel internal combustion engines, a plurality of operating programs are used. The first of these programs, as an initial stage, works on the basis of automatic regeneration. The second of these programs provides measures which assist regeneration, for example by increasing the exhaust-gas temperature, in the event of conditions which are unfavourable for regeneration, for example on account of unfavourable driving cycles. The third of these programs has the purpose of reactivating the damaged components in the event of non-irreversible damage to the components of the exhaust-gas system.
