Experimental Study of the Spray Characteristics of n-Butanol/Diesel Blends

Abstract:

we studied the spray characteristics of n-butanol/diesel fuel blends using a high-speed camera and schlieren system, and analyzed the effect of different fuels, ambient pressure and injection pressure conditions on the spray penetration, spray cone angle, spray area, et al. The results showed that, at the same injection pressure, as the increase of ambient pressure, the spray cone angle of the same volume of fuel increases gradually, the spray penetration and the spray area decreases; under the same ambient pressure, the spray penetration, spray cone angle and spray area increase gradually with the increasing injection pressure, but when the injection pressure increases enough, the parameters are roughly the same; and the parameters basically all increase with the adding of n-butanol.
