. . . . . . . . Catalytic emission control systems are installed on nearly all vehicles produced today, in order to reduce emissions and enable compliance with legislation. Although they can achieve very high efficiencies once they reach their operating temperatures, there is still scope for improvement during the cold start period of the vehicles. Global Emissions Management looks at...

Systems to reduce emissions of nitrogen oxides (NOx) from vehicles are now well established, generally based on single technologies, either selective catalytic reduction (SCR) or NOx adsorber catalysts (NACs). Global Emissions Management looks at work to combine the two to achieve even higher NOx conversions than each of the separate technologies.
