Abstract: The laser holograph and image processing method was used to analysis the spray property of the unlike double impinging injector The experimental results indicate:The increase of injection angle and the decrease of ratio of two injection orifice diameter or two injection flow momentum could result in the decrease of drop diameter and spray split length The liquid film and liquid silk velocity is the same as injection velocity The drop velocity is slightly lower than injection velocity in the initial spray area The experience formula of Sauter diameter were obtained by analyzing of experimental data
