This study tried to investigate the evaporation and ignition of a diesel spray using a rapid compression machine focusing on mixture formation of fuel and air. Swirl velocity and nozzle hole-number were changed in this report. Photography of spray development using high-speed digital video camera and measurement of pressure history showed relationship between air motion and spray evaporation during ignition delay period. In the case of low swirl, wall impingement of spray and rich mixture formation near injector outlet restrain spray evaporation. In the case of high swirl, spray interference for a large hole-number injector strongly affects spray evaporation.
