  • Device for introducing an additive into an exhaust gas
    Publication number: 20020162322
    Abstract: A reducing agent or an additive that releases an agent is often added to an exhaust gas from engines in order to chemically convert constituents, in particular nitrogen oxides, in the exhaust gas. To achieve intimate mixing of the exhaust gas with the reducing agent or additive over a short section of the gas duct, at least one mixer and at least one nozzle for introducing the additive into the exhaust gas are structurally and functionally combined with one another.
