Emission control are focused area in engine development. One of the important methods to reduce the nitrogen oxide (NOx) is recirculating the exhaust gas into intake of engine. In the present work the numerical simulation is carried out using commercial software ANSYS with focus on the effect of NOx emissions in the exhaust of CI (diesel) engine with exhaust gas recirculation (EGR). For the analysis purpose we assume CO2 as exhaust gas, which is to be recirculated. This study is performed with and without EGR for the comparison. Simulation result shows that at the start of combustion the formation of nitrogen mono oxide (NO) are greater than nitrogen dioxide (NO2) but later on since most of NO get oxidized to NO2 its emissions get reduced. Results also show that with EGR both NO and NO2 significantly reduces. However, there is slight reduction of power and slight increase in CO and CO2 emissions are observed.
