Simultaneous laser-induced incandescence and light scattering measurements were used to obtain images of the evolving soot field within an optically-accessible DI diesel engine. Optimum signal collection parameters were established based on preliminary measurements in an ethylene diffusion flame. The effects of intake air temperature on soot formation during diesel combustion were investigated. Although increased soot production was evident for the higher intake air temperature cases, local particle diameters and number densities of the soot were unaffected for each of the cases tested.
