A new technique which combines the forward and backward light scattering method and an image processing method has been developed to measure the characteristics of high concentration fuel jet spray. The time histories of spatial distributions of droplet size and volume density in jet spray are obtained by this technique form two photographs of forward and backward scattering intensities of spray injected in the collimated pulsed laser light. The method demonstrated for measurement of Diesel fuel sprays under various injecting conditions. The distributions of the injected fuel volume obtained by this technique are compared with those calculated simply from injection rate and injecting velocity. The experimental results indicate that this technique is very effective for measuring the distributions of droplet size, volume density and behavior of high concentration sprays under various operating conditions.
