Method and apparatus for selectively reducing NOx in an exhaust gas feedstream |
| abstract |
A method and apparatus are described to selectively reduce NOx emissions of an internal combustion engine. An exhaust aftertreatment system comprises an injection device operative to dispense a hydrocarbon reductant upstream of a silver-alumina catalytic reactor device. A control system determines a NOx concentration and hydrocarbon/NOx ratio based upon selected parameters of the exhaust gas feedstream and dispenses hydrocarbon reductant during lean engine operation. Included is a method to control elements of the feedstream during lean operation. The hydrocarbon reductant may comprise enginefuel. |
