采用高压共轨系统与高速摄影系统，实验测量液体燃料在跨临界条件下，喷雾贯穿距离与雾化角度的变化。实验结果表明启喷压力变大和背压变小会导致喷雾贯穿距离增大；雾化角度只与背压有关，背压越大，雾化角度越小。
採用高壓共軌繫統與高速攝影繫統，實驗測量液體燃料在跨臨界條件下，噴霧貫穿距離與霧化角度的變化。實驗結果錶明啟噴壓力變大和揹壓變小會導緻噴霧貫穿距離增大；霧化角度隻與揹壓有關，揹壓越大，霧化角度越小。

In this work, a common-rail system for the high pressure injection is used here to explore the the primary factors that influence the fuel's spray. A high speed camera is used here to measure the spray penetration and spray-plume angle. The result of the experiment shows that an increase in injection pressure and a decrease in ambient pressure will cause an increase in spray penetration. The spray-plume angle increases only because the ambient pressure decreases.
