Abstract In recent years, it is necessary and indispensable that the internal combustion engine should be improves thermal efficiency from the view point of environmental problems for decreasing exhaust gas. However, the analysis of combustion is very difficult in an actual engine, because construction of the combustion chamber is complex and volume changes by strokes. Then, we use a constant volume combustion bomb that can be controlled turbulence flow. It is effective to analysis of turbulent combustion. We measured velocity by LDV that doesn't influence on flow. And we calculated the characteristic value of flow. Moreover, we took pictures of flame section with laser sheet method and analyzed the image. With those results, the purpose is to throw light on the effect of flame by turbulence intensity and frequency in combustion bomb.
