Exhaust particulate in diesel engines is affected by fuel properties, but the reason for this is not clear. Interest in using low-grade fuels in diesel engines makes it urgent to clarify the particulate formation mechanism and factors to decreasa it. With a fluid reaction tube and nitrogen atmosphere, this report investigates the amount and configuration of the particulate, and analyzes polycyclic aromatic hydrocarbons (PAH) of fuels with different molecular structures and carbon numbers. The following results were obtained: (1) Starting formation temperature of particulate depends on the fuel properties. (2) The soot precursor has at most three, four, or five rings of PAH. (3) The formation of the particulate takes place via polycyclic aromatic hydrocarbons by condensation polymerization and dehydrogenation.
