This project investigates the use of dimethyl ether in diesel engines as alternative fuels. DME is produced 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 and emission characteristic softheengineunderfiveengineloadsatthemaximumtorque.DME’sdieselengine- compatible properties are its high cetane number and low auto-ignition temperature. In addition, it’s simple chemical structure and high oxygen contentresultinsoot- re ecombustionin engines. The dimethylether issued as an alternative fuel mean stone hence the engine combustion. The Diesel 100% (only diesel), and DDE50 (diesel 50% and Dimethyl lether50%) and DME 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. In comparison with neat diesel, the DDE50 blends have50% higher brake thermal efficiency (BTE). The experimental results showed that the CO, HC and NOx emission is decreased for all DDE blends. The brake specific fuel consumption (BSFC) decreased for all DDE blends compared to neat diesel fuel
