FTP Emissions Test Results from Flexible-Fuel Methanol Dodge Spirits and Ford Econoline Vans

A Comparative Analysis of Emissions Deterioration for In-Use Alternative Fuel Vehicles

“…The general test procedures, emissions test driving profiles, hydrocarbon speciation, and other facts about this program are reported in other publications. [5][6][7] The National Alternative Fuels Data Center (AFDC), located in Golden, CO, collects and reports data from these emissions tests.…”

“…From this database, researchers are becoming more confident about emissions values for various AFVs. Studies conducted by the National Renewable Energy Lab on this data, [5][6][7] as well as several independent studies, [8][9][10] have quantified emissions values for heavy-and light-duty vehicles operating on fuels such as compressed natural gas, methanol, ethanol, propane, and reformulated gasoline (RFG).…”

Fuel-cycle emissions for conventional and alternative fuel vehicles : an assessment of air toxics.

“…The values in the middle column of Table 4.12 are somewhat higher than values in Kelly et al (1996a), who tested six MY93 M85 Dodge Spirits and obtained values of 1.23% benzene, 0.22% acetaldehyde, 10.86% formaldehyde, and 0.09% butadiene. They are also higher than values from Black et al (1998), who presented data from a single MY93 Ford Taurus (0.59% benzene, 0.07% acetaldehyde, and 4.90% formaldehyde).…”
