| Abstract(J) | 環境対応の高度化により，出力・燃費と排ガス低減の両立には開発効率化が不可欠である．多段噴射は排ガスに影響するが，幅広い運転条件における3D-CFD解析は計算コストが高い．そこで，CFD結果に基づく縮退モデル（ROM）を構築し，様々な噴射タイミングでの筒内状態量を素早く推定する手法を提案する． Translation |
| Abstract(E) | Improving development efficiency is essential to achieve high performance, fuel economy, and emission reduction. Multiple injection strongly influences emissions, while 3D CFD analyses over a wide range of operating conditions require high computational cost. This study proposes a method to estimate in-cylinder states under various injection timings using a Reduced-Order Model (ROM) derived from CFD result. |
