The relationship between Diesel fuel composition and that of the solvent organic fraction of Diesel particulates was investigated for an old DI Petter engine and a current technology DI Perkins engine. Polynuclear aromatic compounds (PAC) were identified using high resolution capillary column chromatography with a parallel triple detector system for polycyclic aromatic hydrocarbon (PAH), nitrogen containing PAH (PANH) and sulphur containing PAH (PASH). The Perkins engine gave emissions with much lower unburnt hydrocarbons than Petter engine and this was shown to be due mainly to the much greater efficiency of burn out of low molecular weight fuel compounds including n-alkanes and PAH.
