    摘要： Systems and methods are disclosed that include an exhaust gas stream produced by an engine and an aftertreatment system including an SCR catalyst element receiving at least a portion of the exhaust gas stream. An exhaust outlet flow path has an inlet fluidly coupled to the exhaust gas stream at a position downstream of at least a portion of the SCR catalyst element that bypasses at least a portion of exhaust gas stream to provide for compositional measurement of the exhaust gas with a compositional sensor located downstream of a diagnostic catalyst positioned in the exhaust outlet flow path.

    摘要： An arrangement and method for reducing the nitrogen oxide content in the exhaust gas of an internal combustion engine with the aid of ammonia and/or ammonia-releasing reduction agents, whereby ammonia and/or ammonia-containing reduction agent is added to the exhaust gas stream upstream of a catalyst combination composed of an SCR catalyst and a subsequent NH3-oxidation catalyst in such a way that a homogeneous mixture of exhaust gas and ammonia is present upstream of the SCR catalyst. To optimize the reaction or conversion of nitrogen oxides, disposed downstream of the combination of a first SCR catalyst and a first NH3-oxidation catalyst is at least one second catalyst having SCR activity in order in this way to reduce the nitrogen oxides formed at the first NH3-oxidation catalyst due to insufficient selectivity of the catalyst to nitrogen with not yet oxidized NH3.

    摘要： The invention provides an exhaust gas purification apparatus for an internal combustion engine which evenly diffuses a reducing agent over an entirety of the exhaust gas which flows into an NOx catalyst disposed on the downstream side of thereof. The exhaust gas purification apparatus includes an NOx catalyst disposed in an exhaust gas passage of an internal combustion engine, and a reducing agent injecting unit for injecting the reducing agent into the exhaust gas passage which is on an upstream side of the NOx catalyst. A narrowed portion, in which a cross-sectional area of a flow passage is smaller than a cross-sectional area of the exhaust gas passage and of the NOx catalyst, is provided on a downstream side of an injecting position by the reducing agent injecting unit and the upstream side of the NOx catalyst, and a reducing agent diffusing device is provided on the narrowed portion.
