Imaging of Gasoline-like Sprays with Planar Laser-induced Exciplex Fluorescence using a DualScope

Image of gasoline-like sprays

The role of the fuel injection systems in direct injected gasoline engines is to achieve a suitable fuel vapor distribution, homogeneous or with some degree of stratification, while avoiding unwanted effects such as wall wetting. Planar Laser-Induced Exciplex Fluorescence (LIEF) is a method suitable for the characterization of such sprays since it enables separate imaging of both vapor and liquid phase of fuel simultaneously.
