    摘要: A procedure to introduce a reagent substance into the exhaust duct of an internal combustion engine and a device to implement the procedure are proposed. At least one catalytic converter is disposed in the exhaust duct of the internal combustion engine. In front of the aforementioned catalytic converter(s), a reagent substance subjected to pressure is sprayed into the exhaust gas. The reagent substance pressure set point is established as a function of a parameter. The procedural approach allows for a targeted employment of the reagent substance and a high degree of utilization of the converter.
