Summary:

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 has made it necessary to understand the particulate formation mechanism and factors to decrease it.Particulate formation has been reported to start with thermal cracking of the fuel to lower boiling point hydrocarbons followed by condensation polymerization and production of benzene ring compounds; the formation of particulate takes place via polycyclic aromatic hydrocarbons.This report investigates the amount and configuration of particulate with a fluid reaction tube and in a nitrogen atmosphere, and analyzes polycyclic aromatic hydrocarbons (PAH) of fuels with different molecular structure and carbon number.The results were: (1) Starting formation temperature of particulate depends on fuel properties, (2) The amount of particulate increases with the C/H ratio. (3) The soot precursor PAH has at most three, four, or five rings
