Painting a clear picture of how nitrogen oxides are formed
(World News Science)

Nitrogen oxides (NOx) are some of the most significant pollutants in our atmosphere - they contribute to the formation of smog, acid rain and ground-level ozone. Because of this, combustion researchers and engine companies have been working since the 1980s to understand how these gases are produced during combustion so that they can find ways to reduce them. In a new review paper published in Progress in Energy and Combustion Science, researchers from the U.S. Department of Energy`s Argonne National Laboratory and the Technical University of Denmark explain how they synthesized more than a decade`s worth of combustion studies to create a new overarching model of how nitrogen oxides are...
