Abstract

The National Renewable Energy Laboratory (NREL) has been working with the Regional Transportation District (RTD) of Denver, Blue Sun Biodiesel, and Power Service Products to evaluate the in-use performance of buses operating on B20 (20% biodiesel and 80% conventional diesel fuel). Nine mechanically identical 40-foot transit buses (five operated on B20, four on conventional diesel) are being compared over the same duty cycle, the 'Skip' route in Boulder, Colorado. In addition, laboratory tests compared the buses for fuel economy and emissions. This report summarizes the interim results for the period August 2004 through February 2005.
