Abstract

A system for adding and processing reducing agent includes an injector connected to a reducing agent metering unit and which can spray a jet of reducing agent into the exhaust gas. A mixing pipe is disposed in an exhaust pipe of the internal combustion engine and a funnel element is disposed on or in the mixing pipe in the region of the first mixing pipe end. The mixing pipe and the funnel element are formed as hollow bodies having perforated outer surfaces, the perforation of the mixing pipe has a larger surface area than the perforation of the funnel element. The funnel element has a passage opening on the end of the funnel element assigned to the first mixing pipe end, and the reducing agent metering unit is disposed such that the injector sprays the jet of reducing agent through the passage opening into the interior of the funnel element.
