This paper documents results from an experimental study performed to determine the effects of several ultra-low sulfur diesel (ULSD) fuels (< 15 ppm S) on exhaust emissions from a 1,500 kW EMD 16-645-E, roots-blown, diesel locomotive engine. U.S. EPA-regulated emission levels of hydrocarbons (HC), carbon monoxide (CO), oxides of nitrogen (NOx), and particulate (PM) were measured using U.S. EPA locomotive test procedures while operating on four ULSD fuels, plus a fifth baseline fuel which was a commercially-available Federal on-highway diesel fuel (< 500 ppm). The four ULSD fuels were (1) a ULSD California motor vehicle diesel fuel (CARB fuel) with an aromatic content of less than 10 percent, (2) a ULSD “equivalent” California motor vehicle diesel fuel with an aromatic content of 24 percent, (3 and 4) two custom blended “2006 ULSD Federal” diesel fuels with relatively low Cetane Numbers and higher aromatic levels. This paper reports the changes observed in the regulated exhaust emission levels between the ULSD CARB diesel fuels and the ULSD Federal diesel fuels.

Detailed Chemical

Derived from natural gas, coal, and even biomass Fischer-Tropsch (F-T) diesel fuels have a number of very desirable properties. The potential for emissions reduction with F-T diesel fuels in laboratory engine tests and on-road vehicle tests is well documented. While a number of chemical and physical characteristics of F-T fuels have been attributed to the observed reduction in emissions, the actual effects of both the fuel properties and in-cylinder combustion characteristics in modern diesel engines are still not well understood. In this study a 2002, six-cylinder, 5.9 liter, Cummins ISB 300 diesel engine, outfitted with an in-cylinder pressure transducer. was subjected to a subset of the Euro III 13-mode test cycle under steady-state operating conditions. Emissions and in-cylinder pressure measurements were conducted for neat F-T diesel, low sulfur diesel (LSD), ultra-low sulfur diesel (ULSD), and a blend of FT/LSD. In addition, a detailed chemical analysis of the fuels was carried out. The differences in the measured combustion characteristics and fuel properties were compared to the emissions variations between the fuels studied, and an explanation for the observed emissions behavior of the fuels was developed.

Conventional switcher or shunting locomotives in North America are powered by a single 12 or 16 cylinder engine which operate at eight distinct power levels, plus idle. Recently introduced locomotive power systems utilize multiple smaller displacement non-road diesel engines packaged as individual generator sets to obtain a cleaner and more efficient locomotive. This paper examines exhaust emissions and fuel consumption of a Railpower RP20BD switcher locomotive utilizing three 375 kWe generators. FTP tests, described in part 92 of the CFR Title 40, were completed for UPY2606 using two fuels: EPA certification diesel, and ultra-low sulfur diesel. The locomotive produced emissions well below EPA Tier 2 limits using certification fuel, and subsequent testing with ULSD further reduced emissions to below the future EPA Tier 2 and 3 limits.

To meet demands for improvements in the CO,NOx and smoke intensity and fuel economy from diesel engine,the emulsified diesel fuel are choose as alternative fuel .It is prepared through selecting appropriate compound-surfactants on the basis of the HLB (hydrophilic and lipop- hilic balance) value.Comparative experiments between the emulsified fuels and diesel are undertook based on engine bench test in the model 295A diesel engine without any modification. The results indicate that smoke intensity and NOx emissions are reduced greatly when using the emulsified fuels ,especially for those with glucose Solution.Besides,The fuel consumption of the emulsified fuels s are less than that of pure diesel and the economy characteristic from diesel engine is better.
