Vehicles emit exhaust gases as a result of the combustion of fossil fuels. Various exhaust gases are emitted from the engine bases on various Conditions that develop within the combustion chamber. These gases can either be treated and then sent to the atmosphere via tailpipe, Some amount being used in the purpose of exhaust gas recirculation (EGR) Or sent through the tailpipe without any treatment. Gases such as nitrogen oxides (NOx), carbon monoxide (CO), hydrocarbons (HC), Particulate matter (PM), volatile organic compounds (VOC), And in some cases smaller amount of sulphur dioxide (SOx) and ammonia (NH3). Nitrogen oxides (NOx): NOx refers to NO and NO2 and it is produced due to the combustion at very high temperatures. At higher temperatures, … Continue reading Vehicle Exhaust Gases
