Coal-water slurry operation in an EMD diesel engine

摘要: The U.S. Department of Energy, Morgantown Energy Technology Center has assumed a leadership role in the development coal-burning diesel engines. motivation for this work is obvious when one considers magnitude domestic reserves coal and wide-spread use reported paper represents preliminary engine experiments leading to coal-burning, medium-speed engine. basis effort two-stroke, 900 rpm, 216-mm (8.5-inch) bore manufactured by Electro-Motive Division General Motors Corporation. engine, minimally modified form, been operated several hours on slurry 50 percent (by mass) water. Engine operation was achieved configuration using pilot injection fuel ignite main charge slurry. A standard unit injector, slightly increasing diametrical clearances injector pump nozzle tip, used inject Under operating conditions evaluated, combustion efficiency NO/sub x/ emissions were lower than, particulate higher corresponding results. These initial results, without optimizing system coalmore » slurry, demonstrate potential utilizing fuels.« less
