SwRI engineers help develop post-refinery diesel treatment that overcomes soot/NOx tradeoff for cleaner burning fuel

Green Car Congress

Internal combustion engines, when burning a fuel-air mixture, produce harmful pollutants such as soot and NO x. To decrease emissions, engineers design and calibrate engines to adjust combustion temperatures, but have been stymied by the soot/NO x trade-off.
