| Abstract(J) | 点火プラグをホットスポットとするプレイグニッションを予測可能な1D-CFD用熱面着火モデルを構築した．既報のノックモデルと同様，筒内残留ガス中のNOが着火遅れ時間を短縮する影響を考慮することの重要性を示した．さらに，本モデルにより実機における点火進角に伴うプレイグニッション現象を再現可能であることを確認した． Translation |
| Abstract(E) | The first report revealed that NO in the residual gas of Hydrogen-fueled spark ignition engines significantly reduces ignition delay time. This report presents a 1D-CFD model for predicting pre-ignition due to thermal surface ignition, incorporating the effects of NO. In experiments, spark plug temperatures were measured to investigate the mechanism of pre-ignition. Using these experimental results, in-cylinder flow and thermal source temperature were modeled, leading to the construction of the pre-ignition prediction model. The model successfully reproduced the pre-ignition phenomena observed in actual engines when advancing the ignition timing. |
