本文叙述了作者所设计建立的高速纹影摄影光路系统,给出了利用该系统所拍摄的纹影照片,并通过照片简单分析了柴油机缸内的喷雾和燃烧过程。结果表明,纹影技术是研究发动机缸内空气运动和喷雾燃烧过程的有效手段。 This paper describes the high-speed slit photographic optical system designed by the author, gives the tattoo pictures taken by the system, and simply analyzes the spraying and burning processes in the diesel cylinder by the photos. The results show that the shadowing technology is an effective method to study the air movement and spray combustion process in the engine cylinder.
