Abstract:
A 1993 Ford Taurus Flexible Fuel Vehicle (FFV) designed to operate on gasoline or methanol has been modified to run on Ed85 (85 vol.% denatured ethanol, 15 vol.% gasoline) and has demonstrated the ability to meet California's Ultra-Low Emissions Vehicle (ULEV) standards. The vehicle maintains the excellent driveability with potentially increased performance and similar efficiency to the baseline vehicle. Using standard twin OEM catalysts, FTP-75 emissions were 0.085 g/mi NO\dx, 0.88 g/mi CO, and 0.039 g/mi reactivity-adjusted NMOG. Using close-coupled catalysts upstream of the OEM catalysts, FTP-75 emissions were 0.031 g/mi NO\dx, 0.297 g/mi CO, and 0.015 g/mi reactivity-adjusted NMOG. The catalysts were aged to about 4,000 miles equivalent use. These emissions compare with ULEV standards of 0.2 g/mi NO\dx, 1.7 g/mi CO, and 0.04 g/mi NMOG at 50,000 miles of use
