Abstract
Flame structure of a spark ignition engine under the conditions of lean burn limit was investigated. The experiment was performed with propane air mixture of equivalence ratios of 0.50 and 0.55. The flames had a small structure that the unburned gas was entrained into the burned gas, or were obstructed by turbulence and the partial quenching was observed. Fractal analysis was performed for the flame boundaries of the obtained images. The values of the fractal dimension under lean limit conditions reached 1.45 larger than that of non-reaction turbulence.
