Abstract : The purpose of this study is to investigate macroscopic spray characteristics according to blending of
diesel and gasoline fuels. The macroscopic spray characteristics were analyzed through the comparison of the
injection quantity, the spray tip penetration and the spray cone angle due to the variation of the injection
pressure and the fuel properties. Test fuels used in this work were diesel-gasoline fuels with 20%, 40%, 60%
and 80% of gasoline fuel by volumetric fraction. Fuel density, kinematic viscosity, surface tension and flash
point of blended fuels were measured and analyzed. Spray behavior characteristics were analyzed through
spray images, which were obtained from the spray visualization system.
It was revealed that the properties of test fuels, such as density, kinematic viscosity, and surface tension
were decreased with the increase of gasoline quantity. At the short energizing duration conditions, the
injection quantity of test fuels showed almost similar level. However, the injection quantity for gasoline
blended fuels showed decreasing trend at a long energizing duration. In diesel-gasoline blended fuels, the
spray tip penetration characteristics were showed similar values with pure diesel fuel. Spray cone angle was
slightly increased with the increase of gasoline blending ratio.
