Description

The purpose of this study is to understand evaporation and ignition phenomena and the mixture formation process of the diesel spray near the ignition position at the ignition timing. In this study, we measured the ignition region and ignition delay of diesel spray from OH radical emission and analyzed the quantitative distribution of mixture concentration by the laser induced exciplex fluorescence (LIEF) method. It seems that ignition occurs near the tip of the spray, where there is no liquid phase and the air-fuel mixture becomes homogeneous due to entrainment of the ambient air.
