| 摘要： | A technology demonstration of Ford F-150 series bifuel COMPRESSED NATURAL GAS (CNG) or gasoline Qualified Vehicle Modifier (QVM) vehicles was conducted at Ft. Bliss, Texas. The demonstration program at Ft. Bliss was a continuation of the initial fleet of General Motors dedicated CNG 1992 pickup trucks, which was prematurety hatted due to CNG cylinder failures at locations other than Ft. Bliss. This Department of Energy sponsored fleet consisted of 25 General Services Administration (GSA) owned, Army leased 1995 bifueled Ford F-150 1/2-ton pickup trucks. The data that this demonstration would yield included overall engine performance, vehicle operation and maintenance, fuel economy, and assessment of exhaust emissions. As a result of this demonstration program, the data has shown that the bifued vehicle fleet's performance was extremely satisfactory. Mechanically, the vehicles performed equally satisfactorily with gasoline and CNG fuel. The combined gasoline and CNG fuel economy calculated from actual usage data shows an 11-percent decrease when compared to the regulated federal test procedures (FTP) calculations. FTP emissions tests were performed on three selected vehicles using CNG and gasoline fuels at 4,000-10,000- and 20,000-mile intervals. The data showed dramatic reductions in non-methane organic gas, non-methane hydrocarbons, and carbon monoxide when operated on CNG There was, however, a small increase in oxides of nitrogen emissions with CNG. |
