Abstract: This paper presents a study about the effect of injection pressure on the spray characteristics of diesel fuel containing dissolved gas (CO2), using LDSA and speed photographic equipment. It indicates that dissolving gas into diesel fuel to improve the atomization only work in a specific scope of injection pressure. Meanwhile, according to experiment data, the method of curve fit is used to estimate the droplet SMD of diesel fuel containing dissolved gas of different concentration with differe

Key words: diesel fuel containing dissolved gas, injection pressure, spray characteristics

摘要： 运用激光粒度分析仪（LDSA）和瞬间高速摄影等装置，就喷射压力对溶解有二氧化碳气体的柴油喷射雾 化特性的影响进行研究。研究结果表明将CO2气体溶解于柴油只能在特定的喷射压力范围内改善喷射雾化。同 时，依据柴油喷射雾化粒径的实验数据，采用曲线拟合的方法建立了计算不同溶气量的柴油在不同喷射压力下喷 雾液滴的索特直径（SMD）的经验公式。
