AB This article presents a study of the atomization behavior of a steady spray of fuel containing dissolved gas. Using diesel fuel containing dissolved CO2 and air, experiments were performed under atmospheric conditions on a diesel hole-type nozzle and simple nozzles. The atomization process and spray characteristics were observed and measured by instantaneous shadowgraphy and LDSA (an optical technique based on a narrow-angle forward-scattering theory), respectively. The effects of the concentration of dissolved gas, the injection pressure, and the nozzle L/D ratio were examined. The results show that: (1) the injection of fuel containing dissolved gas (IFCDG) can greatly improve the atomization and produce a parabolic-shaped spray; and (2) in terms of atomization, there exist two completely contrary effects of the IFCDG. The beneficial effect of the IFCDG is obtained at a gas concentration above the transition and in the region of larger nozzle L/D ratio.
