摘　　要：基于直喷汽油机和高速相机,搭建汽油机缸内可视化平台,拍摄喷雾过程图像,利用Matlab对图像进行后处理和分析,去除背景噪声、壁面反射光和个别亮点的影响,提取了喷雾的贯穿度、喷雾面积信息。该方法是研究汽油喷雾贯穿度、喷雾形态的有效手段。A cylinder visualized platform is constructed, consisting of an optical engine with direct fuelinjection and a high speed camera to take the photo images of fuel spraying process, and the images are thenpost-processed and analyzed with Matlab to eliminate the effects of background noise, the reflective light fromwall surface and bright spots, and to extract the information of the penetration and the longitudinal sectionalarea of spray. The method adopted is an effective means for studying the penetration and the morphology ofgasoline spray.
