    摘要： The invention relates to an exhaust gas post treatment system for an internal combustion engine, in particular for a heavy fuel oil-powered marine diesel internal combustion engine, comprising an SCR catalyst (13), which uses ammonia as a reducing agent for the denitration of the exhaust gas, and having a device (15, 15a, 15b) positioned upstream of the SCR catalyst (13) as seen from a flow direction of the exhaust gas, by way of which ammonia or an ammonia precursor substance, which in the exhaust gas is converted to ammonia, can be introduced into the exhaust gas upstream of the SCR catalyst (13). Downstream of the SCR catalyst (13) and optionally, of a turbocharger, an exhaust gas scrubber (16) is positioned, by way of which excess ammonia, which is contained in the exhaust gas leaving the SCR catalyst (13), together with sulfur oxides, which are likewise contained in the exhaust gas leaving the SCR catalyst (13), can be scrubbed out of the exhaust gas forming ammonium salts while maintaining a pH value of approximately 6. For the control thereof, a bypass (20) around the SCR catalyst (13) can be provided as a wastegate, or comprising an additional SCR catalyst (21) .

    摘要： Deterioration of a selective catalytic reduction (SCR) catalyst (5) can be diagnosed with sufficient accuracy, by making use of a sensor (7) for measuring an air fuel ratio of exhaust gas flowing into an exhaust gas purification apparatus, which is equipped with the SCR catalyst (5), and a further sensor (8) for measuring an air fuel ratio of exhaust gas flowing out from the exhaust gas purification apparatus. In an exhaust gas purification apparatus for the exhaust gas purification apparatus, in a time period in which inducement-processing is carried out which is to induce a water gas shift reaction in a catalyst disposed at the upstream side of the SCR catalyst (5), by changing an air fuel ratio of exhaust gas discharged from an internal combustion engine (1) from a lean air fuel ratio into a predetermined rich air fuel ratio, an air fuel ratio of exhaust gas flowing into the SCR catalyst (5) and an air fuel ratio of exhaust gas flowing out from the SCR catalyst (5) are measured by said air fuel ratio sensors (7, 8), respectively, and deterioration of the SCR catalyst (5) is diagnosed based on a difference between the measured values of these sensors, wherein the inducement-processing is carried out when the amount of NH 3 adsorption in the SCR catalyst (5) is equal to or less than a predetermined amount.
