The development and combustion of a small-volume diesel spray simulating a pilot injection was experimentally investigated in a constant volume vessel. Liquid and vapor phase of spray were visualized by Mie scattering method, and LIF method respectively under nonflammable condition. In addition, the spray combustion was also observed by high-speed shadow graph imaging. Experimental results show that the small-volume spray loses its momentum rapidly due to the throttle effect in nozzle seat section. Then, most of injected fuel remains around the nozzle exit, and it is vaporized as the result of thermal diffusion from entrained air.
