Optimization of Gasoline-Dissolved CO2 Injectors

An experimental study on flashing injection of gasoline-dissolved CO2 mixtures through specially designed injectors was performed. The injectors used comprised an expansion chamber, prior to the discharge orifice, in order to promote the CO2 flashing. Malvern Mastersizer-X was used to measure the spray characteristics. High-speed digital video camera was employed to visually register the expansion chamber flow patterns. The geometry of the …
