Abstract
A previous paper reported (SAE Paper 2002-01-2884) that it was possible to decrease mode-weighted NOx emissions compared to the OEM calibration with corresponding increases in particulate matter (PM) emissions. These PM emission increases were partially overcome with the use of oxygenated diesel fuel additives. We wanted to know if compounds of toxicological concern were emitted more or less using oxygenated diesel fuel additives that were used in conjunction with a modified engine operating strategy to lower engine-out NOx emissions. Emissions of toxicologically relevant compounds from fuels containing triproplyene glycol monomethyl ether and dibutyl maleate were the same or lower compared to a low sulfur fuel (15 ppm sulfur) even under engine operating conditions designed to lower engine-out NOx emissions. The emissions of toxicologically relevant compounds using a 100% Fisher Tropsch fuel, a recognized clean fuel, were equivalent to or less than emissions from the two oxygenated diesel fuels. These results suggest that these oxygenated diesel fuel additives can be used to lower engine-out NOx emissions without risking any increase in tailpipe emissions of compounds of toxicological concern.
