Educational Outcomes Embedded Within Energy Conservation Projects By Cliff Mirman, Chair, Department of Technology and Promod Vohra, Dean, College of Engineering and Engineering Technology Northern Illinois University, Dekalb, Ill 60115AbstractDuring the summer of 2008, the NIU College of Engineering and Engineering Technologyreceived funding from the United States Department of Energy to study modes of energyconservation in the railroad industry. Specifically, the projects looked at reducing the usage ofdiesel fuel in the operation of today’s modern locomotives. The project lasted one and a halfyears, and five tasks examined unique aspects energy conservation of the locomotive. The teamstudied the usage of alternate fuels as a suitable alternative to using straight diesel fuel, wherecost, availability, emissions, and material wear are key considerations. The team also studied theusage of fuel cell power systems in the propulsion of the train. The team examined many safetyand power issues that centered on this form of energy source. In addition to energy sources, theteam examined the thermal and emission reduction of the locomotives. With new federalregulations coming in the future, this area will not only reduce the energy consumption, butcompanies will be required to comply with federal regulations. The research and design teamalso studied the usage of energy efficient materials in the railroad industry. It was found thatcomponents can be made lighter and have longer life spans if alternative materials are used.Finally, the team examined tribology issues. Friction issues constitute many energy inefficienciesof the locomotive, from the wheels rolling on the tracks, to the friction of the massive 16cylinder engines, to the other wear surfaces of the locomotive; friction issues greatly reduce theefficiency of the train.Much work was completed in developing new energy efficiencies in this important industry,however, more importantly, the work completed was interdisciplinary and the faculty membersinvolved included a large group of both graduate and undergraduate students. Ten facultymembers from four different areas were involved in this work. In addition, the project used theexpertise of over 20 undergraduate and graduate students. In addition to the work which wasdeveloped, the project management was an important portion of the project, from an overallperspective down to each student component. Students in all areas made positive impacts on theproject and much was accomplished towards energy improvement in the railroad industry.
