Abstract (en)
[origin: WO2005099874A1] A method for introducing a reagent into an exhaust gas channel (12) of an internal combustion engine (10) and a device for carrying out the method are proposed. At least one catalytic converter (15) is disposed in an exhaust gas channel (12) of the internal combustion engine (10), a pressurised reagent being sprayed into the exhaust gas prior to the catalytic converter. The set value for the pressure of the reagent (pReaSw) is determined as a function of a performance characteristic (N, mL, Md, mK, vabg, pabg, TabgR, TRea). The procedure as per the invention allows targeted use of the reagent and a high utilisation of the catalytic converter (15).
