| Abstract(J) | スーパーリーンバーンエンジンでの放電挙動と着火過程について，点火時の放電電流・放電期間や各筒内燃焼特性等から検討を加えた．同エンジンでの着火過程はペクレ数によって整理可能であることが示唆され，また，放電期間や放電の伸長が着火や初期燃焼過程に強く影響することを明らかにした． Translation |
| Abstract(E) | Super lean-burn is one of promising technologies to improve the thermal efficiency of SI engine. This article reports on the spark discharge characteristics and the ignition process in super lean-burn SI engine based on experimental data such as discharge current, discharge duration, combustion duration and in-cylinder photograph. The results implied that the ignition process could be evaluated by Peclet number, and the ignition ability and the early stage of the combustion process were strongly influenced by an effective discharge duration and the elongation of the spark channel. |
