    摘要： Various embodiments of an apparatus, system, and method are disclosed for reducing NOx emissions on an SCR catalyst. For example, according to one representative embodiment, an apparatus for reducing NOx emissions in an engine exhaust includes a NOx reduction target module that is operable to determine a NOx reduction requirement that includes an amount of NOx in the exhaust gas stream to be reduced on a selective catalytic reduction (SCR) catalyst. The apparatus also includes an ammonia target module that is operable to determine an ammonia addition requirement that includes an amount of ammonia added to the exhaust gas stream to achieve the NOx reduction requirement. The apparatus also includes a reductant target module that has a hydrolysis module and an inverse hydrolysis module. The hydrolysis module is operable to determine a predicted amount of ammonia and isocyanic acid entering the SCR catalyst. The inverse hydrolysis module is operable to determine a reductant injection requirement based at least partially on the predicted amount of ammonia and isocyanic acid entering the SCR catalyst.

    摘要： An exhaust gas treatment system for an internal combustion engine comprises an exhaust gas conduit configured to receive and to deliver exhaust gas to a downstream exhaust treatment device. An injector bay extends outwardly from the exhaust gas conduit upstream of the exhaust treatment device and an exhaust fluid injector mounts through an opening in the injector bay and is in fluid communication with the exhaust gas conduit and oriented in an upstream direction to deliver an exhaust fluid to the exhaust gas in the upstream direction. An exhaust flow baffle extends outwardly from the injector bay and into the exhaust gas in an upstream direction. The exhaust flow baffle is located upstream of the exhaust fluid injector and is configured to define a turbulent, low pressure velocity field downstream thereof and proximate to the exhaust fluid injector.

    摘要： A NOx reduction catalyst and an ammonia slip oxidation catalyst are disposed in an exhaust system in this order, and also, an electric fan is disposed on piping which communicates an upper space of a storage tank storing therein a reducing agent with the exhaust upstream of the NOx reduction catalyst. Then, when the temperature of the ammonia slip oxidation catalyst reaches or exceeds the temperature for activating a catalyst thereof, the electric fan is operated for a predetermined period of time, so that the gas (ammonia series gas) in the upper space of the storage tank is forcibly discharged to the upstream side of the NOx reduction catalyst. Further, a discharge-forcing device, such as an electric fan or the like, forcibly discharging the gas in the upper space of the storage tank, an adsorbing device temporarily adsorbing thereto the forcibly discharged gas and an oxidation catalyst oxidizing the gas desorbed from the adsorbing device, may be disposed to the storage tank in this order.
