Behavior of gasoline hollow cone spray at pressurized condition was studied. Swirl type fuel injector was used. Surrounding pressure was varied 0.1∼0.5 (MPa) which covers the surrounding pressure of compression stroke. The spray behavior was observed by LLS (Laser Light Scattering) method and LDV (Laser Doppler Velocimeter). Spray angle was narrower when fuel injection period was longer and surrounding pressure was higher. The pressure difference between spray inside and outside effects the spray angle change. The Spray pattern at pressurized surrounding condition was canged by the initial center distributed spray.
