Method and apparatus for generating a reductant in an exhaust gas of a compression-ignition engine |
摘要 |
A method and apparatus are provided for generating a reductant in an exhaust gas feedstream of a compression-ignition internal combustion engine upstream of a hydrocarbon-selective catalytic reduction catalyst. The method comprises injecting a quantity of fuel into the exhaust gas subsequent to a combustion event whereat a temperature of the exhaust gas is in a range of 670 K to 1100 K at a start of the injection. The generated reductant comprises an active species including an oxygenated fuel species.
