In this study, in order to understand soot formation characteristics in diesel jet flame on various combustion conditions, effects of experimental parameters (such as ambient gas temperature, ambient oxygen concentration, and injection pressure) on soot volume fraction and particle diameter distribution in diesel jet flame was investigated using Time-Resolved Laser-induced incandescence. The experiments were conducted using constant combustion vessel which simulated diesel engine conditions. The experimental results show that the small soot particles generated at upstream of the jet was carried to downstream and grow to the large soot particles by aggregation or surface growth. And soot volume fraction was reduced by ambient gas temperature and oxygen concentration decrease, injection pressure increase.
