Analysis in Unsteady Evaporating Gasoline Spray with LIEF Method

エキサイプレックス蛍光法(LIEF 法)を用いた非定常蒸発ガソリン噴霧の解析

Direct injection gasoline engine has higher thermal efficiency than conventional port fuel injection gasoline engine. However, it is necessary to make the air-fuel mixture in a short time and it is difficult to control the air-fuel mixture. Therefore, in order to elucidate the liquid phase and the vapor phase of gasoline spray in the air-fuel mixture formation process, the visualization of spray and analysis was carried out by using the LIEF method.筒内直接噴射式ガソリンエンジンはポート噴射式ガソリンエンジンと比較して,高い熱効率を有しているが,短期間で混合気を形成しなければならないため,混合気濃度の制御が難しい.そのため,混合気形成過程における噴霧挙動を解明する必要がある.そこでLIEF 法を用いてガソリン噴霧の可視化および解析を行なった.
