Development of a novel fuel injection systems (NFIS) for dimethyl ether - And other clean alternative fuels

摘要

A novel, electronically controlled, common rail fuel injection system has been designed and developed by the authors under a contract from the National Renewable Energy Laboratory (NREL). This system was specifically designed for direct injection of liquid dimethyl ether (DME) to achieve ultra-low emissions of NO{sub}x and particulate matter from conventional diesel engines. However, the system's basic characteristics also make it suitable for direct injection of ethanol and methanol in compression-ignition engines, and direct injection of liquid propane and gasoline in spark-ignition engines.
