In this paper the characteristics of evaporating fuel sprays injected into a high pressure and temperature cylindrical vessel arc investigated by means of an electronically controlled common rail injection system. A laser induced fluorescence method was used to separate vapor and liquid phases of the spray. Two methods were conducted to investigate the qualitative and quantitative applicability of the technique in a high pressure and temperature atmosphere during the fuel injection period. Firstly, we calibrated the relationship between fluorescence intensity and vapor concentration of dopants at different temperatures. Secondly, we calculated the spray evaporation processes using the KIVA-3 code, which is commonly used in engine combustion simulations. Then, the distributions of fuel vapor concentration in diesel sprays were analyzed.
