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.
Abstract Diesel engine spray field is a transient spray field with high speed motion lasting only a few milliseconds. It is of great significance to study the change of particle size distribution of diesel engine spray field over time on the combustion process of diesel engine. Of the fog field characteristics developed by the laser diffraction transient fog field measurement system.The system can be repeated in a single spray cycle diesel engine fog field sampling can be measured in a spray cycle spray fog particle size distribution over time The characteristics of the variation.The thesis also introduced the measurement of particle size distribution of diesel transient spray field using this system.
