The objective of this study was to analyze the effect of mixed fuel composition and mass fraction on spray inner structure in evaporating transient spray under the variant ambient conditions. Spray structure and spatial distribution of liquid phase concentration were investigated using a thin laser sheet illumination technique on the three component mixed fuels. A pulsed Nd:YAG laser was used as a light source. The experiments were conducted in a constant volume vessel with optical access. Fuel was injected into the vessel with electronically controlled common rail injector. Used fuel contains i-octane(C?H<SUB>18</SUB>), n-dodecane(C<SUB>12</SUB>H<SUB>26</SUB>) and n-hexadecane(C<SUB>16</SUB>H<SUB>34</SUB>) that were selected as low-, middle- and high-boiling point fuel, respectively. Experimental conditions are 42 ㎫, 72 ㎫ and 112 ㎫ in injection pressure, 5 ㎏/㎥, 15 ㎏/㎥ and 30 ㎏/㎥ in ambient gas density, 300 K, 500 K, 600 K and 700 K in ambient gas temperature, 300 K and 368 K in fuel temperature and different fuel mass fraction. Experimental results indicated that the multi-component fuels made two phase region mixed vapor and liquid so that it would are helpful to improve combustion, for the fuels of high boiling point component could accelerate evaporation very much according as low boiling point fuel was added to high boiling point fuel.
