采用高速摄影技术在一个定容容器内 ,对溶有 CO2 的燃油在常温常压、常温高压、高温高压 3种环境条件下的喷射过程进行了观察和测量研究。发现对溶有 CO2 的燃油喷射 ,喷雾特性的主要影响因素是环境温度和压力 ,在常温常压、高温高压 2种环境条件下 ,溶气燃油发生闪急沸腾 ,喷雾初始锥角大 ,最大喷雾宽度大 ,大大地促进了燃油的雾化。并对溶有 CO2 燃油的喷射过程机理进行了探讨
A high-speed photographic technique was used to observe and measure the jetting process of CO2-dissolved fuel under three kinds of environmental conditions: normal temperature and pressure, normal temperature and pressure, high temperature and high pressure. It was found that the main influencing factors of spray characteristics for CO2-soluble fuel injection were ambient temperature and pressure. Under ambient conditions of normal temperature and pressure and high temperature and high pressure, dissolved fuel flash boiling, the initial cone angle of spray, the maximum spray Large width, greatly promoted the fuel atomization. The mechanism of injection process of CO2-dissolved fuel was also discussed
