| Abstract(J) | 隣接ディーゼル噴霧火炎間干渉がすす粒子の酸化に与える影響を調べるため，実機燃焼室模擬定容容器及び多噴孔ノズルを用い，干渉領域におけるすすの挙動を可視化すると共に，すす粒子性状を時空間分解サンプリング及びＴＥＭ解析する手法を確立した．可視化では干渉領域で酸化抑制傾向が示唆されたが，ＴＥＭ解析では明確な酸化抑制は確認されなかった．これは膨張行程が無く，ＯＨによる酸化が助長されたためと考えられる． Translation |
| Abstract(E) | In order to investigate the effect of diesel flame-to-flame interaction on soot oxidation, soot luminosity in the diesel flame-to-flame interaction regions was visualized and spatio-temporally resolved sampling and TEM morphological analysis of soot particles were conducted using a pancake-shape constant-volume vessel with a centrally mounted multi- hole injector mimicking actual engine chamber geometry. The soot luminosity long stagnated around the flame-to-flame interaction region implying some oxidation suppression. However, TEM analysis did not show clear oxidation suppression being contradictory to engine-out soot results, which may be due to the absence of expansion in the vessel experiment resulting in excessive oxidation. |
