Behavior of Fuel Spray injected by Tailpipe Injector for Post Treatment of Diesel Engine Emissions (Fourth Report)

ディーゼルエンジン排気管内インジェクタから噴射される 後処理用燃料噴霧の挙動 (第4報)

The authors focused on the behavior of spray in tailpipe. Wall impingement phenomenon in the tailpipe is different from phenomenon in the engine cylinder. In this study, they calculated the wall impinging spray in a low injection pressure spray with the model which considering the change in the impingement behavior due to the boiling state. By using this model, the wall impingement behavior of the spray is predicted with high accuracy.後処理に用いられるDPF再生手法として,排気管内に燃料を噴射するSFIが適用されている.本研究では排気管内のHC挙動を高精度に予測可能な数値モデルの構築を目的とする.本報では,沸騰形態による衝突挙動を考慮した壁面衝突モデルを用い,低圧噴霧における壁面衝突挙動の解析を行った.
