摘要:There is provided a method and apparatus for exhaust gas purifying, especiallyNOx reduction. The apparatus comprises an internal combustion engine adapted to
operate primarily lean of stoichiometry. There is an aftertreatment system that is fluidlyconnected to and adapted to treat exhaust gas flowing from the internal combustionengine. The aftertreatment system comprises a hydrocarbon-selective catalytic reductiondevice. There is an injector device adapted to inject a blend of fuel and an ignitionimprover into the exhaust gas at a location upstream of the hydrocarbon-selectivecatalytic reduction device. A control module is adapted to control the injector device toinject the blended fuel and ignition improver into the exhaust gas when temperature ofthe exhaust gas at the location of the injection is greater than about 280°C.
