This study examines the use of the infrared extinction technique to measure spatial and temporal fuel vapor distributions in pulsed evaporating sprays. An infrared extinction instrument with collinear visible and infrared laser beams was designed and constructed. The instrument configuration was validated using a methane absorption cell in conjunction with a nonabsorbing liquid spray. A production automotive fuel injector using isooctane as the fuel was quantitatively characterized. Vapor results from the injector were obtained in a time-resolved manner with a temporal resolution of 0.2 ms. The spray was interrogated at several axial positions. Additionally, the results were smoothed and deconvoluted to provide spatially resolved, quantitative vapor-phase information for the spray. Discussion is provided regarding the liquid and vapor distributions in the transient spray environment.
