J. Broz et al., The effect of oils on PAH, PCDD, PCDF, and PCB emissions from a spark engine fueled with leaded gasoline, CHEMOSPHERE, 41(12), 2000, pp. 1905-1911
The effect of synthetic and mineral oils on the formation of polyaromatic h
ydrocarbons (PAHs), polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofuran
s (PCDFs), and biphenyls (PCBs) in emissions from a spark ignition engine w
as studied on a Skoda Favorit engine fueled with leaded gasoline. The test
cycle simulated urban traffic conditions on a chassis dynamometer, in accor
dance with the ECC 83.00 test. The data for selected PAHs as well as PCDDs,
PCDFs, and PCBs congener profiles are presented. PCDD/Fs emissions for an
unused oil and the oil after 10 000-km operation varied from 300 to 2000 fm
ol/m(3) PCBs emissions from 75 to 178 pmol/m(3), and PAHs emissions from 15
0 to 420 mu g/m(3). The content of PCBs in oils vaned from 2 to 920 mg/kg.
