Abstract
This study was conducted to analyze the impact of low level bio-alcohols that can be applied without modification of vehicles to improve air quality in Korea. The emissions and fuel economy of low level bio-alcohols mixed gasoline fuels of spark ignition vehicles, which are direct injection and port fuel injection, were studied in this paper. As a result of the evaluation, the particle number (PN) was reduced in all evaluation fuels compared to the sub octane gasoline without oxygen, but the correlation with the PN due to the increase in the oxygen content was not clear. In the CVS-75 mode, emitted CO tended to decrease compared to sub octane gasoline, but no significant correlation was found between NMHC, NOx and fuel economy. In addition, it was found that the aldehyde increased in the oxygenated fuel, and there was no difference in terms of the amount of aldehyde generated among a series of bio-alcohol mixed fuels.
