Development of multi-focus particle analyzer with bundle fiber

为了减少柴油发动机的排放，需要燃油喷雾的雾化。为了对高速、高密度的颗粒物进行定量测量，需要研制一种新的测量装置。在本研究中，一种新的多点测量系统的特点是一束光纤。测量体采用双焦点微探针结构，实现了柴油颗粒速度和粒径的多点同时测量。

Atomization of fuel spray is required for reduction of emissions in a diesel engine. In order to measure high-speed and high-density particulates quantitatively, a new measurement device needs to develop. In this research, a new multi-point measurement system is developed with featuring a bundle fiber. The measurement volume has micro-probe structure with two foci, and the particle velocity and size of diesel fuel are measured simultaneously at multi-point.
