| Research Abstract |
The purpose of this study is to investigate auto-ignition mechanism and soot formation of unburned mixture compressed by propagating flame. Compression-expansion machine were used. I investigated as follows ; (1) auto-ignition of unburned mixture of hydrogen compressed by propagating flame were visualized, (2) soot formation under low-temperature chemistry, effect of fuel component on soot formation, soot formation during premixed charge compression ignition, soot formation near wall due to pressure wave, were investigated in order to understand luminous flame during engine knocking.
