Method for adding at least one reactant to an exhaust gas flow of an internal combustion engine and an exhaust gas flow treatment device for an internal combustion engine

摘要

The method involves partial conversion and partial separation of a component of an exhaust gas stream (5). A reactant stream (10) is added to the exhaust gas stream such that a part of the reactant stream meets on the element (3). The reactant stream includes a drop of 30 micrometers in the diameter. A decomposition reaction of one component of the reactant stream takes place in the area in which the reactant stream meets the element. The reactant stream comprises a reducing agent and a reducing agent precursor. An independent claim is also included for a device for processing an exhaust gas stream of an internal combustion engine.
