• The effect of wall interaction on the soot processes of a diesel fuel jet was investigated in an optically-accessible constant-volume combustion vessel at experimental conditions typical of a DI diesel engine. Soot processes were studied in both free jets and plane wall jets at identical operating conditions. Soot distributions were visualized using planar laser-induced incandescence and quantitative soot measurements were performed using a laser extinction technique. The investigation showed that soot levels were significantly lower in a plane wall jet compared to a free jet. Possible mechanisms for the decrease hi soot upon wall interaction include an increased fuel/air mixing rate and a wall jet cooling effect, which would tend to reduce or delay soot formation.
