• Abstract:
  In the U.S., there were more than 5,000 commuter rail diesel locomotives in use in 2011. Many of these have head end ; power (HEP) engines that provide power for hotel services in the passenger cars. The North Carolina Department of ; Transportation owns six diesel passenger locomotives that have recently replaced HEP engines. The general goal of this work ; is to quantify the in-use emission rates of these engines on ultra low sulfur diesel (ULSD) fuel and evaluate the effect of soybased ; B20 biodisel fuel on each engine. The specific research objectives are to: (1) evaluate the effect of engine load on ; emission rates of CO, HC, NOx, and PM; (2) compare B20 versus ULSD with respect to emission rates of CO, HC, NOx, and PM; ; (3) compare to emission standards taking into account differences in measurement methods; (4) evaluate the inter-engine ; variability in emission rates; and (5) estimate an emission inventory of CO, HC, NOx, and PM for the HEP engines. As ; expected, fuel use and emission rates are sensitive to engine load. Cycle average PM emission rates were 20% lower for B20 ; than for ULSD, with no significant measured change in emission rates of other pollutants.
