The team of researchers developed a novel diesel oxidation catalyst design which utilises less precious metal, while improving performance. Diesel oxidation catalysts for heavy-duty diesel engine emission reduction are required to remove hydrocarbons and carbon monoxide from the exhaust. At the same time, the catalysts provide additional functionality to facilitate removal of soot and nitrogen oxides by the downstream soot filter and selective catalytic reduction catalyst.

With this catalyst in the front of the emission control system, it is possible to meet the most stringent of current emission control regulations. As this catalyst is currently used on-road in all major markets, the positive impact on air quality could have global reach. Moreover, this catalyst significantly broadens the temperature region to implement removal of soot and prevent buildup of backpressure on the engine, thereby reducing fuel consumption.
