Abstract: The in-cylinder flow dramatically affects combustion performance and emission characteristics of a compression ignition engine. The spray cone angle is among the most critical factors affecting mixture formation, combustion and emissions in a direct injection diesel engine. We have used three-dimensional computational investigations on spray cone angle-induced emission pattern of V-type DI engine under AVL-FIRE and ESE simulation interface. Four spray cone angles of 120°, 130°, 140°, and 150° were used for simulation purpose. The findings from the three-dimensional AVL-FIRE simulation confirm the influence of spray angle on optimal air-fuel mixing and, hence, combustion. Spray cone angle of 140° gave better engine performance in terms of lower CO and soot emission, but increased NO emission was observed due to improved combustion.
