摘要
摘要柴油机喷雾场是高速运动的持续时间只有数毫秒的瞬变喷雾场,实际测量柴油机喷雾场粒径分布随时间的变化对柴油机燃烧过程的研究具有重大意义.本文介绍的测量系统是我们针对柴油机的雾场特点研制的激光衍射瞬变雾场测量系统.该系统可以在一个喷雾周期内连续多次对柴油机雾场进行取样,可以测量在一个喷雾周期内喷油雾场粒径分布随时间的变化特性.本文还介绍了使用该系统进行的柴油机瞬变喷雾场粒径分布实测研究.
A research work was carried out on measurement of the temporal droplet size distribution of fuel spray based on the principle of laser diffraction. By using the laser diffraction measuring system developed by the authors a continuous and multi-sampling measurment of the temporal droplet size distribution was made, and the variation of droplet size distribution with time within the injection period was obtained.
