Abstract

Spay characteristics of diesel oil/dimethoxymethane (DMM) blends were investigated in a constant volume bomb. The results show that, at the same ambient pressure and nozzle hole diameter, the spray angle increases and spray tip penetration decreases with the increase of DMM fraction in the blends. Meanwhile, spray angle increases, while spray tip penetration decreases with the increase of ambient pressure. Correlation between spray angle and ambient pressure is θ ∝ p_a^0.15. During the early stage of injection, spray tip penetration is linear with time, while after the fuel breaking-up, it appears as an exponential relationship of s∝tⁿ. The value of n decreases with the increase of DMM fraction in the blends. In the case of pure diesel fuel, n is 0.6, and in the case of pure dimethoxymethane fuel, n is 0.5.
