发动机喷雾和燃烧过程的多功能动态可视化测试装置的研制和应用

Dynamic Visualization Test Setup With Multiple Functions for Spray and Combustion Process in Engines

为研究发动机的燃烧和排放形成,研制了一种多功能可视化摄影用的动态燃烧装置。该装置主要包括:摄影用发动机、光路系统、供油系统、起动装置、同步控制和采样系统及高速数码摄影系统;具有使用、维护简单,成像清晰的特点。使用情况、拍摄图像和测得的示功图表明,该装置是研究发动机喷雾和燃烧的一种先进工具。

This paper reported a dynamic visualization photographic setup with multiple functions to provide an important mean to study combustion and the form of emission. The installation composed of a visualization engine, an optical system, a fuel-supply system, a start-up installation, a control system, a data collection system and a photographic system. The use results show that it is an advanced tool to study spray and combustion process in engines.
