NOx and diesel enginesOctober 2016 | Articles
NOx refers collectively to air polluting chemical compounds (NO, NO2 and N2O). It is a pollutant which has been associated with, amongst other things, childhood asthma and acid rain. Click here to find out more about the effects of NOx on the environment.
NOx is produced when diesel or petrol is burned, but because of a variety of factors, it is produced in greater quantities in diesel engines. Experts generally agree that there is a trade-off between the production of NOx (which is generally higher when the engine is running more efficiently) and the production of CO (carbon monoxide) and CO2 (carbon dioxide) emissions, and the fuel economy, performance and noise levels of a vehicle.
