The abundance and distribution of the alkyl homologues of polycyclic aromatic hydrocarbons (naphthalene, fluorene, phenanthrene, pyrene, fluoranthene, and phenylnaphthalene) and oxygenated polycyclic aromatic hydrocarbons (naphthalenecarboxaldehydes, fluoren-9-one, biphenylcarboxaldehydes, phenanthrenecarboxaldehydes, and thioxanthen-9-one) in the organic extractables of particulates produced by a diesel engine are reported. Samples were obtained at three engine loads and at three fuel injection timing conditions. The concentrations of alkyl homologues of polycyclic aromatic hydrocarbons (PAH) and oxy-PAH on the particulates were found to decrease as cylinder exhaust temperature increased. The degree of alkylation for the most abundant homologue of these compounds increased by one to two carbons as the cylinder exhaust temperature was decreased.
