Patent ID: 7062903

Claim:
A device for introducing a processing agent downstream of an engine into an exhaust gas of an internal combustion engine flowing one of into an aftertreatment system and into a particle filter, comprising: an arrangement for supplying the processing agent; a supply apparatus provided with a reciprocally acting arrangement for exciting a gas discharge, wherein: an at least partial oxidation of the processing agent is supported prior to entering the aftertreatment system; and an arrangement for conveying the exhaust gas and via which a reciprocal action of the supply apparatus and the reciprocally acting arrangement for exciting the gas discharge are implemented, wherein: the arrangement for conveying the exhaust gas subdivides a region between the supply apparatus and the reciprocally acting arrangement for exciting the gas discharge in such a way that the processing agent first mixes with a portion of an exhaust-gas stream before being conveyed to the reciprocally acting arrangement for exciting the gas discharge, the supply apparatus and the reciprocally acting arrangement for exciting the gas discharge are arranged in such a way relative to one another that a supply of the processing agent to the reciprocally acting arrangement for exciting the gas discharge is implemented in a direction that is perpendicular to a flow direction of the exhaust gas, the arrangement for conveying the exhaust gas includes three orifices, a first orifice of the three orifices conveys a portion of an exhaust-gas flow to the supply apparatus, a second orifice of the three orifices conveys a further portion of the exhaust-gas stream to the reciprocally acting arrangement for exciting the gas discharge, and a third orifice of the three orifices discharges the exhaust gas mixed with radicals into the aftertreatment system.
