A mixture formation from a direct injection gasoline spray plays an important role of combustion and emission formation processes. A spray shape, which is related to the mixture formation, is influenced by ambient pressure, ambient temperature, fuel temperature and so on. In this study, the ambient temperature in the constant volume bomb was changed to investigate the effect of surrounding on spray shapes. Also the fuel temperature was changed. Moreover, OH radical from spray combustion was visualized by chemiluminescence. As a result, the injected spray behavior with high fuel temperature and these combustion characteristics were made clear.
