Abstract:

The objective of this project was to assess the effects of various blends of biodiesel on locomotive engine exhaust emissions. The ; emission tests were conducted on two locomotive models, a Tier 2 EMD SD70ACe and a Tier 1 Plus GE Dash9-44CW, using two ; baseline fuels: (1) conventional EPA ASTM No. 2-D S15 certification diesel fuel and (2) commercially available California Air ; Resource Board (CARB) ULSD fuel. A single batch of soy-based B100 was mixed in with the EPA and CARB diesel to yield a 5 ; percent and 20 percent blend of fuel. A randomized test matrix was used to perform triplicate tests on each of the six test fuels ; (EPA0, CARB0, EPA5, CARB5, EPA20, and CARB20). ; General emissions and fuel economy trends seen in other studies and applications for biodiesel use were also observed in this ; study. Higher blend levels of biodiesel were associated with lower carbon monoxide and particulate matter, as well as with higher ; levels of nitrogen oxides and fuel consumption. Use of diesel fuel with 20 percent biodiesel often resulted in statistically ; significant differences from the fuel with 0 percent or 5 percent biodiesel, while the difference between 0 percent and 5 percent ; biodiesel was generally not statistically significant.
