Alternative Fuel Light-Duty Vehicles: Summary of Results from the National Renewable Energy Laboratory's Vehicle Evaluation Data Collection Efforts
5/1/1996
The U.S. Department of Energy's National Renewable Energy Laboratory conducted a data collection project for light-duty, alternative fuel vehicles (AFVs) for about 4 years. The project has collected data on 10 vehicle models (from the original equipment manufacturers [OEM]), spanning model years 1991 through 1995. Emissions data have also been collected from a number of vehicles that were converted to operate on compressed natural gas (CNG) and liquefied petroleum gas. Most of the vehicles involved in the data collection and evaluation are part of the General Services Administrations's fleet of AFVs. This evaluation effort addressed the performance and reliability, fuel economy, and emissions of light-duty AFVs, with comparisons to similar gasoline vehicles when possible. This report includes results from emissions testing completed on 169 AFVs and 161 gasoline control vehicles. Alcohol vehicles in general indicated equivalent or lower regulated emissions compared to reformulated gasoline. CNG vehicles did show significantly lower emissions than gasoline vehicles. Preliminary emissions results from vehicles that have undergone aftermarket conversion are not as promising as for OEM AFVs. Conversion emissions in many cases were higher than the vehicle emissions were before conversion.

Compressed Natural Gas and Liquefied Petroleum Gas Conversions: The National Renewable Energy Laboratory's Experience
4/1/1996
The National Renewable Energy Laboratory contracted with conversion companies in six states to convert approximately 900 light-duty Federal fleet vehicles to operate on compressed natural gas (CNG) or liquefied petroleum gas (LPG). This report shows how this program has been successful in helping the Federal government meet the vehicle acquisition requirements of EPACT, establishing infrastructure, increasing the displacement of imported oil, and evaluating the emissions performance of converted vehicles.

Round 1 Emissions Test Results from Compressed Natural Gas Vans and Gasoline Controls Operating in the U.S. Federal Fleet
1/1/1996
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 were collected on regulated exhaust emissions using the federal test procedures, and on a number of other quantities, through a statistically controlled program of investigation. 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. The data analysis conducted thus far indicates that the compressed natural gas vehicles exhibit notably lower regulated exhaust emission, on average, than their gasoline counterparts, and that these values are well within U.S. Environmental Protection Agency standards. In addition, lower levels of toxic constituents are emitted by the compressed natural gas vehicles relative to their gasoline counterparts and they produce lower levels of ozone precursors as well. Performance measures include driver acceptance, fuel economy, operational cost, cost and level of maintenance, and emissions output. The most extensive effort of its kind, the AMFA evaluation program targets three alternative fuels - methanol, ethanol, and compressed natural gas (CNG) - and encompasses several different types of vehicles, makes, and models operated in a number of federal service applications at various sites around the country. This paper specifically addresses the emissions performance of light-duty federal fleet AFVs operating on CNG. The data represents solely from Round 1 of a three-round testing program (hence, emissions deterioration is not specifically addressed).
