The combined exhaust gas aftertreatment systems (DPF+SCR) are the most eficient way and the best available technology (BAT) to radically reduce the critical Diesel emission components particles (PM&NP) and nitric oxides (NOx). SCR (selective catalytic reduction) is regarded as the most eficient deNOx-system, diesel particle ilters are most eficient for soot abatement. Today, several suppliers offer combined systems for retroitting of HD vehicles. Quality standards for those quite complex
