      Final Report
    • Abstract:
      The Biodiesel Mass Transit Demonstration report is intended for mass transit decision makers and fleet managers considering biodiesel use. This is the final report for the demonstration project implemented by the National Biodiesel Board under a grant from the Federal Transit Administration. This report evaluates the extended in-use performance of biodiesel (a blend of 20% biodiesel and 80% ultra low sulfur diesel) in an independent engine test and two separate field demonstrations, specifically: a 1,000 hour engine durability test conducted by Southwest Research Institute (SWRI); an over-the-road field test with the St. Louis Metro Bus Transit System implemented by the National Renewable Energy Laboratory (NREL); and an over-the-road field test with the Kansas City Area Transportation Authority led by the National Biodiesel Board (NBB). The results from the demonstration indicate that on-spec biodiesel can serve as a drop-in replacement fuel in existing diesel equipment. This report provides an introduction, a background, and a summary of the methodology and the research approach; reviews the results; and presents conclusions and lessons learned. This report also summarizes federal and state regulations that may impact fuel choice by transit agency operators. The project also produced a comprehensive report, printed under separate cover and titled, "Biodiesel Fuel Management Best Practices for Transit."
