Abstract | In 2004, DOE's National Renewable Energy Laboratory led an evaluation of the emissions of transit buses operated by the Washington Metropolitan Area Transit Authority (WMATA). The goal of this project was to evaluate the emissions of natural gas transit buses and the improving baseline emissions of comparable diesel buses with advanced emission control technologies. The buses were tested for numerous regulated and unregulated emissions, including hydrocarbons, carbon monoxide, oxides of nitrogen, particulate matter, and various toxic emissions. The analysis demonstrated the emissions advantage of CNG buses as well as promising fuel economy results for the CNG buses compared with the diesel buses. |
