For Power Generation diesel engines are predominantly being used due to higher thermal efficiency and fuel efficiency compared to petrol engines. With increase in awareness of air pollution and global warming all over the world government organisations have started announcing legislations to limit exhaust emissions for a cleaner and greener environment. In India, Central Pollution Control Board (CPCB) has proposed to introduce the next stage of stringent emission norms for engines used in Power Generation from April 2014 which are comparable to the best in the world. This research work deals with the strategies applied and experimentation details to meet the proposed CPCB Stage-II emission limits. According to CPCB II emission limits, NO<inf>x</inf>+HC emissions for a naturally aspirated diesel engines have to be reduced by 28%. Achieving this target with minimum engine modification will be a difficult task. An experimental study was conducted on a twin cylinder naturally aspirated diesel engine. Various combustion parameters like catalytic converter, direct continuousEGR, static injection timing were optimized in a cost effective manner in order to achieve CPCB II limits with sufficient margin. The experimental study indicates that, the CO emission has been decreased with 20% margin and HC+NO<inf>x</inf> emission has been decreased with 15% margin from CPCB II limits. © Research India Publications.
