Round 1 Emissions Results from Compressed Natural Gas Vans and Gasoline Controls Operating in the U.S. Federal Fleet.

摘要

The first round of emissions testing of light-duty alternative fuel vehicles placed in the U.S. federal fleet under the provisions of the Alternative Motor Fuels Act was recently completed. This undertaking included 75 Dodge B250 vans, of which 37 were dedicated compressed natural gas models, and 38 were standard gasoline controls. Data was collected on regulated exhaust emissions using the federal test procedures, and on a number of other quantities, through a statistically controlled program of investigation. Fuel economy results were also recorded. All test vehicles were operated in routine federal service activities under normal working conditions, adhering as closely as possible to Chrysler's prescribed maintenance schedules.
