OPEN FLAME STUDIES CONTRIBUTE TO UNDERSTANDING OF DIESEL SMOKE

When combustion duration in a direct injection diesel engine cylinder was measured using a flame luminosity detector, smoke level was found to increase as combustion extended beyond exhaust valve opening. Parallel studies of continuous-spray diffusion flame indicate that maximum temperature location corresponds with a region of minimum soot, rather than maximum. Soot formation and oxidation with increasing crank angle following initiation of combustion are similar to those along the axis of an open flame -- thus providing a powerful tool for studying exhaust smoke without in-cylinder constraints and complexities.
