DEVELOPMENT AND APPLICATION OF IMAGING SYSTEM TO EVALUATE LIQUID AND VAPOR ENVELOPES OF MULTI-HOLE GASOLINE FUEL INJECTOR SPRAYS UNDER ENGINE-LIKE CONDITIONS
RÉSUMÉ
A novel high-speed imaging system capable of acquiring schlieren and elastic scattering images in a near-simultaneous fashion along the same line of sight has been developed. Liquid and vapor envelopes of sprays from a multi-hole gasoline fuel injector operating under engine-like conditions were systematically investigated. For the conditions evaluated, the maximum liquid penetration length was found to be inversely proportional to injection pressure. Penetration lengths derived from the elastic scattering envelops and schlieren envelopes were found to be quite similar up until the occurrence of the peak liquid penetration, implying that little vapor exists ahead of the penetrating liquid.
