Nano-size PM Emission from Laminar Diffusion Flame of Diesel Fuel 2007-01-1942

The formation mechanism of Particulate Matter (PM) in a flame and fuel effect on this mechanism, are still under unclear problems. In this study, a fundamental pool combustion flame of diesel fuel was formed and PM emission from the flame was analyzed. As a result, though emission of soot from the flame was not observed, significant number of nuclei mode PM was emitted. From a flame of incomplete combustion, aggregate mode particles increased and nuclei mode particles reduced drastically. When a little mount of lubricant oil was contaminated into diesel fuel, number concentration of nuclei mode particle increased.
