To achieve more improvement of diesel combustion and for health issues, it is important to get the information of soot particle characteristics in the diesel jet plume such as the distribution of soot concentration or particle size. In this study, LII (Laser-Induced Incandescence), especially, TIRE-LII (Time-Resolved-LII) was applied to estimate the particle size under unsteady spray combustion, and soot volume fraction was also measured. To apply TIRE-LII to diesel jet, many LII characteristics were tested by using premixed or diffusion flame bumer and numerical simulation. The result sows that, dense regions of soot dominantly localized in the periphery the downstream of the plume. And as fuel injection progresses, the distribution of large soot particle diameter region extends shifting downstream of the plume.
