Abstract(J) | 著者らは既報で,ガソリンサロゲート燃料に適用可能なコンパクトなすす生成モデルを提案した.本研究では,直噴ガソリンエンジンの始動条件において,異なる冷却水温度の実験結果に対してモデル検証を行った.また,下死点近傍で燃料を噴射した場合にすす排出量が増加する傾向に対し,数値解析によって現象評価を試みた. Translation |
Abstract(E) | In this study, numerical calculations of soot emissions from a DISI engine were performed by using a compact-size soot-formation model previously proposed by authors. We discussed the reproducibility of soot emissions by changing the coolant temperature and the fuel injection timing. In addition, the experimentally observed tendency that soot emission slightly increase under the fuel injection timing near the bottom dead center were clarified based on the calculated results, and the model predicted results were verified. |
