Abstract
Base diesel fuel-propylene glycol ether blends with 1.0 and 2.5Â wt.% oxygen contents were used in order to determine the performance of the diesel engine and its emissions at both full and medium loads and different engine speeds (1000, 2500 and 4000Â rpm). In general, at full load and in comparison with base diesel fuel, the blends show a slight reduction of oxygen-free specific fuel consumption. CO emissions are reduced appreciably for 2.5Â wt.% of oxygen blends, mainly for PGEE and DPGME. NOx emissions are reduced slightly, but not the smoke. Unburnt hydrocarbon emissions decrease at 1000 and 2500Â rpm, but not at 4000Â rpm. At medium load, the effect of the additives is much less significant, due to the fact that the ratio oxygen from additive/oxygen from air is much lower.
