Abstract
The invention relates to a method for mixing an exhaust gas flow with a fluid in an exhaust gas pipeof an exhaust gas system, in which the fluid is injected by means of an injection deviceinto the exhaust gas pipe. The exhaust gas flow is guided in the exhaust gas pipein the area of the injection devicein a direction of flow S parallel to the exhaust gas pipe. The fluid is injected directly onto a deflection elementwhich is arranged in the exhaust gas pipein a central direction of injection E which deviates from the direction of flow S by an angle se, wherein by means of at least one sheet metal partwhich is provided on the deflection elementand which is raised at least partially at an angle sv with reference to the direction of flow S, the exhaust gas flow is diverted with reference to the direction of flow S from its direction of flow S into a central direction of distribution V. Before and after it impacts the deflection element, the fluid is carried along at least partially by the diverted part of the exhaust gas flow into the direction of distribution V and is diverted into the direction of distribution V by the raised sheet metal part
