Characteristics of PM from Laminar Diffusion Flames with Various Surrogate Gasoline Fuels

種々の擬似ガソリン燃料の層流拡散火炎を用いたPM 特性の調査

Since the engine combustion is affected by various engine parameters as well as fuel characteristics, it is very difficult to find out the clear effect of fuel property on it. In order to clarify the change of emission characteristic caused by fuel trend, the authors propose a fundamental flame research method using a small pool flame system. Characteristics of PM exhausted from laminar diffusion flames of gasoline and surrogate fuels were investigated by SMPS (Scanning Mobility Particle Sizer), LPI (Low Pressure Impactor) and combustion type PM analyzer. PM exhausted from flames of various chemical structures such as iso-alkane, cyclo-alkane, olefin and aromatic were also investigated. As the result, it was found that the exhaust-PM concentration and PM size increased with increasing of toluene concentration.本研究では,種々の炭化水素成分を添加した場合の擬似ガソリン燃料を対象に小型プール燃焼装置により形成される層流拡散火炎から排出されるPMの粒径,構成成分および主成分であるすすの性状について調査を行なった.
