    As a basic research to apply an emulsified fuel to a real engine, in this study, an analysis of
    behavior characteristics of the evaporative impinging spray of an emulsified fuel composed of diesel fuel and
    hydrogen peroxide (H20 2) was conducted, and a numerical analysis was performed simultaneously. The
    numerical analysis was carried out by using ANSYS CFX to set the experimental boundary condition, the
    diffusion areas of impinging sprays, and the molar concentration of fuel vapors according to varying mixing
    ratios of the emulsified fuel and changes in the heating temperatures of the impinging plate. In conclusion, the
    results of the study suggest that if an emulsified fuel is to be applied to a real engine, it can improve the
    emission reduction of engine exhaust gases, because the temperature inside the combustion chamber is expected
    to be lowered owing to the latent heat of evaporation of hydrogen peroxide in the emulsified fuel and quick
    mixture formation due to the accelerated evaporation and diffusion of fuel spray inside the combustion chamber.
