This paper presents characteristics of diesel combustion and emissions according to adoption of various combustion chamber shape and multi-spray-angle nozzle. Multi-spray-angle nozzle increases spray mixing by keep away from spray overlap. In this research, it is introduced different combustion chamber shapes. Combustion chamber shapes and injection timing affect emission characteristics due to change target area of spray in the combustion chamber. 7 holes in single row nozzle and 12 holes in double row nozzle were examined. To change combustion chamber shapes, single bowl piston as a reference and double bowl piston were used. Also, experiments were conducted according to different injection timing and injection pressure.
