该论文已在芬兰赫尔辛基举行的第28届CIMAC大会上发表。论文的版权归CIMAC所有。As a result of changes in the U.S. diesel fuel regulations, mandates, and specifications, American railroads are using fuel with up to 5 percent biodiesel (B5), and are faced with the likelihood of receiving biodiesel blends (up to 20percent) for use in diesel locomotive engines. Although biodiesel blends have been in the automotive fuel market forseveral years, there is less experience with regular operation of locomotive engines on these fuels, and a number ofconcerns have been expressed by the locomotive manufacturers and the railroad companies, especially whenbiodiesel concentrations higher than B5 are used. This paper summarizes work funded by the U.S. Department of Transportation Federal Railroad Administration (FRA)supporting the railroad industry in assessing biodiesel fuel issues in locomotives. Details are given for the regulatorydrivers in the U.S. for biodiesel; an experimental program to assess the impact of B5 and B20 on exhaust emissions;Fourier Transform Infrared (FTIR) characterization of biodiesel markers in elastomer and fuel filter components in locomotive engines, and locomotive engine fuel injector deposit characterization using FTIR.
