- Abstract
- This study represents the spray development procedure and atomization regimes for a wide range of injection pressure for the Gasoline Direct Injection (GDI) system. To investigate the effect of injection pressure on the spray characteristics, injection pressure was swiped from 5MPa to 30MPa. Imaging method with a high-speed camera was used to take the spray sequential images, and the atomization regimes were predicted with dimensional analysis. The increase of injection pressure promoted spray atomization, which was supported by sequential spray images and the breakup regimes. However, the spray characteristics did not show significant differences for the injection pressure conditions over 20MPa.
