Paper Title
Effect of cetane improver on the performance and emission characteristics of biodiesel fueled DI diesel engine with exhaust gas recirculation technique
Authors

Abstract
Cetane improver in biodiesel-blend with exhaust gas recirculation technique (EGR) reveals the marginal reduction in NOx emission compared with base line diesel fuel without EGR. Addition of cetane improver, 2-ethyl hexyl nitrate (2EHN) reduces the ignition delay, which in turn minimizes the combustion temperatures. Exhaust gas recirculation (EGR) also reduces the maximum temperature in engine cylinder. The present work signifies the addition of 2% by volume cetane improver in Pongamia biodiesel blends with EGR technique towards NOx reduction. The experiment and investigations were conducted on Single-cylinder, four stroke, naturally aspirated, water cooled, DI diesel engine at constant, speed 1500 rpm and injection pressure 180 bar. The results revealed in improved brake thermal efficiency with increase in EGR percentage and little variation in brake specific fuel consumption. Combustion finished earlier with advanced, ignition and peak pressure by few degrees of crank angle. Marginal NOx reduction found up to 31%, with reduced CO, HC and little variation in smoke emission for B20I with 15% EGR when compared with diesel fuel emissions.

Keywords- Cetane improver, biodiesel-blend, exhaust gas recirculation (EGR), 2-ethyl hexyl nitrate (2EHN), and injection pressure.
