| Abstract(J) | これまで我々はHCCI燃焼のノッキング回避および着火時期制御を同時に達成する手法として，EGRとPFJ点火の併用を検討してきた．PFJから噴出されるラジカルによる燃焼促進により，着火時期制御が可能であると示唆されてきたが，ラジカル添加による着火促進の定量的検討は未だ実施されていない．本研究では0次元計算による活性種の把握と，燃焼の光学的計測により，OHラジカルの噴出・生成挙動について明らかにした． Translation |
| Abstract(E) | Effects of Pulsed flame jet (PFJ) and Exhaust Gas Recirculation (EGR) on the formation behavior of OH radical was investigated in Homogenous Charge Compression Ignition (HCCI). N-butane/air/EGR mixture was combusted in a Rapid Compression Expansion Machine (RCEM) to realize HCCI combustion. EGR ratio was varied from 10 to 40 %. The initial pressure and temperature just before compression was set to the 0.1 MPa and the room temperature, respectively. OH luminosity increased after the increase of the heat release rate. In addition, effects the composition and temperature of PFJ on the OH formation and ignition behavior was investigated by 0-D calculation. As a result, although the ignition delay became shorter with the increase of the PFJ/main chamber ratio, it showed almost constant when the ratio was over about 0.6. |
