his document reports on one particular FTA-sponsored, Fischer-Tropsch (F-T) diesel fuel evaluation program, and it incorporates directly related findings (and the current, ongoing status) of other programs in the same series of FTA programs that have been, or are being, conducted by ICRC/VSE. The type of F-T fuel evaluated can be produced form a variety of US domestic energy resources other than petroleum. The overall technical priorities of these F-T fuel evaluations have been to: 1. Determine whether or not operational problems are likely to occur with F-T diesel fuel over the full spectrum of transit-relevant conditions; 2. Compare directly the fuel consumption of F-T and conventional diesel fuels under well controlled but still realistic on-road conditions in the more severe (than typical transit service) region of the spectrum of heavy-duty, diesel-engine service; 3. Compare the potential environmental impacts, in terms of both engine exhaust emissions and fuel biodegradability, of F-T and conventional diesel fuels under transit-relevant conditions. |
