Description

This paper reports the atomization process of fuel spray in gasoline intake port injection. The classification of the jet configuration using dimensionless numbers in fluid dynamics was estimated that the fuel spray in the port fuel injection condition is in the wavy region. A shadow graph photography was used to visualize the liquid sheet breakup process. It was confirmed that the fuel injected from the nozzle formed a liquid sheet. For the subsequent breakup, it was found that the liquid sheet broke up into droplets with a distribution along the axial distance of the nozzle, and the secondary breakup, in which the droplets broke up into smaller droplets, rarely occurred.
