激光剪切干涉高速摄影技术在火花点火发动机燃烧过程中的应用研究

Study on the Application of Laser Shear - interferometry High - speed Photography to Combustion Process in S. I. Engines

将激光剪切干涉高速摄影技术用于火花点火发动机燃烧过程的研究，拍摄到发动机整个燃烧室内火焰的连续剪切干涉图象。通过图象处理，定量得到燃烧过程中不同曲轴转角时的气缸内温度场，精度较高。

The application of laser shear - interferometry high - speed photography to combustion process in S. I. engines has been studied. The successive shear - intererogram of the flame in whole combustion chamber was recorded by a high - speed camera. The temperature field in cylinder at different crankshaft angle in the process of combustion was obtained quantitatively by image processing.
