中文摘要：

汽油引擎的火焰结构是复杂的并且有分数维的几何学的特征。一个分数维的燃烧模型被用来模仿工作的引擎周期。基于这个模型，分数维的尺寸和狂暴的 premixed 火焰的 laminar 火焰表面区域在不同工作条件下面被学习。试验性的系统主要包括一台光引擎和过去常射击火花点火引擎的狂暴的火焰的图象的一套摄影设备。差别数盒子的方法被用来处理 2D 燃烧图象。与试验性的结果相对照，计算结果证明分数维的燃烧模型是模仿引擎燃烧过程的一个有效方法。学习为火焰结构和它的繁殖提供更好的理解。

英文摘要：

The flame structure of gasoline engine is complicated and has the characteristic of fractal geometry. A fractal combustion model was used to simulate the engine working cycle. Based on this model, the fractal dimension and laminar flame surface area of turbulent premixed flames were studied under different working conditions. The experimental system mainly includes an optical engine and a set of photography equipment used to shoot the images of turbulent flame of spark-ignition engine. The difference box-counting method was used to process 2D combustion images. In contrast to the experimental results, the computational results show that the fractal combustion model is an effective method of simulating the engine combustion process. The study provides a better understanding for flame structure and its propagation.
