PM Formed from Laminar Diffusion Flames of Various Hydrocarbon Fuels


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. Number concentrations and exhaust rate of PM emitted from laminar diffusion flames of gasoline fuels (JIS No.1 and No.2) and hydrocarbon fuels of various chemical structures such as alkane, alkene, iso-alkane, iso-alkene, cyclo-alkane, cyclo-alkene and aromatic were investigated by SMPS (Scanning Mobility Particle Sizer). In addition, relation between PM exhaust rate and RON (research octane number) was discussed.本研究では小型プール燃焼装置を用い,アルカン,オレフィンおよび芳香族といった種々の化学構造を持つ炭化水素燃料やガソリン燃料による層流拡散火炎から排出されるPMについて排出量や粒径といった性状について調査を行った.そして,種々の化学構造および炭素数とPM生成について議論を行った.
