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.

The light duty market in North America is broadly defined as vehicles with a gross weight of 14,000 lb 96,350 kg) or less. Around 17 million of these are sold annually in the US alone, but only about 500,000 are powered by diesel engines. Global Emissions Management looks at the reasons for the imbalance...

Volume 2, Issue 10 (Summer 2007)
With increasing concerns about levels of oxides of nitrogen (NOx) in the atmosphere, retrofit NOx reduction technology is now also being sought to provide a cost-effective means of achieving lower emissions levels from operators’ existing vehicles. GEM looks at a real-world field trial in London, where combined NOx and particulate matter (PM) abatement technologies...
