<p>A system and method for the control of emissions from a diesel engine exhaust, comprises a catalyst (14) to convert NO to NO2, a filter (16) to trap soot and hold it for combustion with the NO2, and a NOx absorber (28), with means to regenerate the NOx absorber by injecting reductant or other reactant (injector 18) upstream of the absorber, and at least during regeneration, passing the exhaust gases leaving the absorber through a three-way catalyst (30).</p> |
