Mixture formation plays as a key element on burning process and controlled by the characteristics if the injection system, the nature of the swirl and turbulence in the cylinder, ad spray characteristics. Mixture formation during ignition process associated with the exhaust emissions.Measurements were made in an optically-accessible rapid compression machine (RCM) with intended to simulate the actual diesel combustion related phenomena. The diesel spray was simulated with the RCM which is equipped with the single-shot common-rail fuel injection system. Diesel engine compression process could be reproduced within the wide range of ambient temperature, ambient density, swirl velocity, equivalence ratio and fuel injection pressure. The examination of the first stage of mixture formation is very important consideration due to the fuel-air premixing process linked with the combustion characteristics. The detail behavior of mixture formation images was captured using the high speed camera.This method can capture spray penetration length, spray angle, spray evaporation and mixture formation process clearly. The spray characteristic such as the penetration length, spray angle and spray area are increasing when the injection pressure increased
