Demonstration of a dme (dimethyl ether) fuelled city bus

摘要

The aim of the project was to demonstrate and evaluate the feasibility of DME (Dimethyl Ether) fuelled buses, through laboratory and field tests. The performance and emission targets of the HD DME engine has been successfully demonstrated and the bus has been converted to accommodate the DME engine and the fuel tank system. Two DME filling stations have been build. Additives for DME lubrication and odor have been selected. A Life Cycle Analysis (LCA) has been made under International Energy Agency (IEA) auspices by some of the project participants. The project has added valuable information, to the over all development of DME fueled vehicles. The strong arguments for DME as a major future fuel are briefly covered including production costs, emissions and feed stock diversity.
