Liquid and vapor penetration of sprays from a multi-hole gasoline fuel injector operating under engine-like conditions were systematically investigated utilizing a high-speed imaging system capable of acquiring schlieren and Mie scattering images in a near-simultaneous fashion. The influences of ambient conditions and fuel properties on the formation of liquid and vapor envelopes were evaluated. In addition to the compilation of an extensive data set, results of the investigation indicate that mixing-limited vaporization modeling can be utilized to predict the maximum liquid penetration of short-duration, multi-plume sprays.
