Nitrogen oxides are the gaseous oxides of nitrogen (N). They are abbreviated NOx because of the various possible compounds with different numbers of atoms: N2O, NO, N2O3, NO2, etc.

If they come into contact with water (also in the form of fog), acids are formed, which irritate the mucous membranes and can even cause lung damage. There is one exception: Nitrogen monoxide (N2O), also known as “laughing gas”. However, this is a greenhouse gas, which damages the protective ozone layer in the upper atmosphere.

  • note that the emission varies widely depending on application temperatures and air/fuel ratios. In general - higher combustion temperature and higher air/fuel ratios increases NOx emissions.


Standards - Norms



Example of a SCR system reducing  NOx: with urea injection.
