Quantitative investigation on the spray mixture formation for ethanol-gasoline blends via UV–Vis dual-wavelength laser absorption scattering (LAS) technique

This study investigated spray mixture formation of ethanol-gasoline blends (E0, E85 and E100) under direct-injection spark ignition-like (DISI-like) condition in a constant volume vessel. An ultraviolet (UV) – visible (Vis) dual-wavelength laser absorption scattering (LAS) technique was used to quantitatively measure the liquid and vapor phase distributions. The toluene with the similar physical properties to gasoline and high absorption for...
