| Abstract(J) | 本研究は，PREMIER燃焼の燃焼現象を解明することが目的である．そのために，エンドガス部自着火火炎の広がり速度が燃焼に与える影響を調査した．手法としては，圧縮膨張機関と高速度カメラを用いてボトム側から燃焼全体を，トップ側からエンドガス部の可視化を行った．PREMIER燃焼に比べエンドガス部自着火火炎の広がり速度が,ノッキングの方が速いことが分かった． Translation |
| Abstract(E) | The purpose of this study is elucidating combustion phenomena of PREMIER combustion. For this purpose, effects of spread rate of the auto-ignition flame in the end-gas region om the pressure oscillation were investigated. The entire combustion and end-gas-autoignition flame were visualized from top and bottom side using compression expansion machine and high-speed camera. Spread rate of auto-ignition-flame area in the end-gas region was calculated by FIV(Flame Image Velocimetry) . It was found that knocking had specific peak of frequency spectrum and the spread rate of the auto-ignition flame was faster than PREMIER combustion. There was a correlation between KI and Spread rate of flame area. |
