초록 The object of this study is to observe the spray characteristics of gasoline-biodiesel fuels when ambient temperature and pressure change. In the experiment, a constant volume combustion chamber(CVCC) was used for spray visualization. Homogeneous mixed gas was used as the atmospheric gas. Characteristics of spray at ambient temperature (60 °, 80 ° C) and ambient pressure at 20 bar, 30 bar, and 40 bar were investigated. Injection parameters were investigated such as spray penetration, spray cone angle and injection pressure. For the spray visualization, the Schlieren technique was used and the image was analyzed using image processing. As a result, the spray penetration tended to be short when the injection pressure was low and the ambient pressure was high, at the same time the spray angle was wide. With higher the injection pressure, the longer the spray shape and the shorter the spray angle.
