Abstract In this research, it has aimed at elucidating the relation between gas flow and flame structure to improve thermal efficiency in internal combustion engine. However, it is extremely difficult to elucidate a combustion phenomenon because structure of internal combustion engine is complicated and changes its capacity. Therefore, we use a constant volume bomb without capacity change. To analyze the relation between characteristic value of turbulence and flame structure, turbulence intensity is measured by LDV and scale of turbulence is measured by hot wire anemometer and flame cross section is measured by the laser sheet method. As a result, when turbulence intensity increases, flame structure becomes complicated. And flame structure doesn't seem to change even if turbulence intensity becomes very strong.
