WebOxides of nitrogen (NOx) are a class of pollutants formed when fuel is burned at a very high temperature (above 1200 °F), such as in automobiles and power plants. For air pollution purposes, it is composed primarily of nitric oxide (NO), nitrogen dioxide (NO2) and other oxides of nitrogen. WebPollutants from diesel engines include carbon monoxide (CO), carbon dioxide (CO2), sulphur oxides (SOx), nitrogen oxides (NOx), and particulate matter (PM). It is possible to reduce pollutant emissions in exhaust gases by using the different kind of fuels and additive, these are significant factors in the composition of exhaust gases.
