A step toward reduced nitrogen-oxide emissions in vehicles

Stricter environmental regulations enacted in the last few years are putting a squeeze on emissions from car engines, including nitrogen oxide. While modern "lean-burn" gasoline and diesel vehicles use less fuel, they also require more oxygen. As a result, traditional three-way catalytic converters – which scrub out the nitrogen oxide, unburned hydrocarbons, and carbon monoxide – don't adequately reduce the rate of nitrogen oxide emissions.
