摘要：This project investigates the use of dimethyl ether in diesel engines as alternative fuels. DME isproduced by the conversion of various feed stock such as natural gas, coal, oil residue sand bio-mass. Diesel –Dimethyl Ether (BDE) wastested in a 4-cylinder direct-injection diesel engine to investigate the performance andemission characteristic softheengineunderfiveengineloadsatthemaximumtorque.DME’sdieselengine- compatibleproperties are its high cetane number and low auto-ignition temperature. In addition, it’s simple chemical structure andhigh oxygen contentresultinsoot- re ecombustionin engines. The dimethylether issued as an alternative fuel mean stonehence the engine combustion. The Diesel 100% (only diesel), and DDE50 (diesel 50% and Dimethyl lether50%) andDME 100% (only dimethylether) were tested in the engine. There sults indicate that when compared with neat diesel,the engine performance increased and emission level decreased with adding the dimethylether with diesel. Incomparison with neat diesel, the DDE50 blends have50% higher brake thermal efficiency (BTE). The experimentalresults showed that the CO, HC and NOx emission is decreased for all DDE blends. The brake specific fuelconsumption (BSFC) decreased for all DDE blends compared to neat diesel fuel
