摘要： An exhaust system for a vehicular lean-burn internal combustion engine includes a NOx reduction catalyst, a source reductant, means (20) for contacting the catalyst with the reductant, means for sensing the temperature of the exhaust gas and/or the catalyst bed and means, when in use, for controlling reductant addition. The reductant addition control means supplies an amount of reductant to the catalyst at a rate corresponding to a measured temperature value of the exhaust gas and/or catalyst bed, which temperature value has been pre-determined to correlate, in use, with an amount of NOx in the exhaust gas.

摘要： Selective catalytic reduction of NOx in combustion gases, especially from diesel engines, utilizes a system incorporating an oxidation catalyst to convert at least a portion of NO to NO2, a particulate filter downstream of the oxidation catalyst, a source of reductant such as NH3 or urea for injection downstream of the particulate filter, and an SCR catalyst located downstream of the point of injection of the reductant. Considerable improvements in NOx conversion are observed.
