This research quantifies the effects of a copper fuel additive on the regulated [oxides of nitrogen (NO{sub x}), hydrocarbons (HC) and total particulate matter (TPM)] and unregulated emissions [soluble organic fraction (SOF), vapor phase organics (XOC), polynuclear aromatic carbons (PAH), nitro-PAH, particle size distributions, and mutagenic activity] from 1988 Cummins LTA10 diesel engine using a low sulfur fuel. Engine was operated at two steady state modes (EPA modes 9 and 11, which are 75 and 25% load at rated speed, respectively) and five additive levels (0, 15, 30, 60, and 100 ppm Cu by mass) with and without a ceramic trap. Measurements of PAH and mutagenic activity were limited to the 0, 30, and 60 ppm Cu levels. The fuel additive had little effect on baseline emissions (without the trap) of TPM, SOF, XOC, HC, or NO{sub x}. The trap reduced TPM from 72 93% compared to baseline, had no effect on NO{sub x}, and reduced HC about 30% at mode 9 with no consistent change at mode 11. 23 refs., 15 figs., 15 tabs.
