Performance and Optimization of Nox Reduction by Urea Spray Formation in SI Engines

Exhaust contains environmentally harmful pollutants such as oxides of nitrogen (NOx) and particulate matter (PM).In order to control these exhaust pollutants engine after treatment technologies are being used in diesel engines. A urea selective catalytic reduction (SCR) is one of the promising after treatment devices for the abatement of exhaust emissions, particularly for NOx pollutants. The basic principal of emission reducing systems is to reduce the NOx pollutants by ammonia formed from urea. This project aims to analyse the NOx emissions from a petrol engine equipped with a Urea catalytic convertor using canister as a catalyst Venugopal A | Sathish Kumar. J | Satish Kumar.
