Spray characteristics of throttle body fuel injection

A research program was undertaken to characterize the spray behavior of a throttle body injection system. Qualitative data were obtained using photomicrography, schlieren photography and videotape. Additionally, the laser based Phase/Doppler Particle Analyzer was used throughout the investigation to make spatially resolved quantitative measurements of droplet size and velocity and fuel volume flux. Spray data were first collected from both an externally mounted ball and an externally mounted pintle injector under steady operation and over a range of injector duty cycles common in engine operation. In subsequent experiments, spray characteristics were measured at the throttle body exit under simulated engine conditions. The study also included correlation of experimental spray results with performance data from throttle body injected engines and a preliminary numerical simulation using the FLUENT finite difference model.
