Panda, Sunil Kumar (2012) Reduction of NOx emission in diesel engine using Exhaust Gas Recirculation. BTech thesis.
Nowadays, internal combustion engines are the essential parts of transportation and mechanized agricultural system. So the consumption of diesel and petroleum has been upsurged. As petroleum is a nonrenewable source and recent surge in petroleum prices have regenerated interest in bio-fuels. It has shown that biodiesel-fueled engines produce less CO, unburned HC and smoke emissions compared to diesel fuel, but higher NOx emissions. Exhaust Gas Recirculation (EGR) is an efficient technique to reduce NOx emission as it lowers the flame temperature in the combustion chamber. The objective of this work is to reduce NOx emission from jatropha biodiesel fueled CI engine. A twin-cylinder, water cooled, constant speed direct injection diesel engine was used for this experiment. The content of HC, NOx, CO and smoke in the exhaust gas were measured to estimate the emissions. Application of EGR with biodiesel resulted in reductions in NOx emissions without any significant upsurge in smoke emissions. The graphs were plotted comparing the emissions from diesel fuel and jatropha biodiesel fuel with 0%, 5%, 10%, 15% EGR.
