In this study, PM exhausted from unsteady pool flame of iso-octane on a shallow dish under various ambient temperature conditions (25 – 700°C) was investigated as fundamental study of fuel film combustion. In addition, PM emissions from the flame of fuel contaminated with lubricating oil were also investigated. Flame appearance from ignition to extinguishment under various ambient temperature conditions was observed. Further, total mass of PM emitted from the flame during flame formation period were measured by a filter method. In addition, real-time PM number concentration measurement was carried out by a Pegasor Particle Sensor (PPS-M). As a result, it was found that total mass and number of PM from pool flame of iso-octane was higher than that of iso-octane with lubricating oil (5wt%). Further, for lubricating oil content condition, deposit on the shallow dish was observed after flame extinguishment.
