This paper presents a research on the influence of combustion chamber geometry on performance and emissions of direct injection diesel engine VIKYNO RV125-2 using threedimensional CFD code KIVA-3V. In this study, the piston bowl depth (pip-height), bottom bowl diameter and bowl diameter are changed while the engine compression ratio is still kept. Research results indicate that increased bowl diameter works best. Specifically, when the bowl diameter changes from 3.98cm to 4.7cm, the engine power is increased 22.6%, while the concentration of NOx is reduced 0.85%. However soot concentration will increase 45.83%.
