In this work, an experimental work is carried out on single cylinder four stroke diesel engine. Dimethyl ether (DME) is used as an additive with diesel in different percentage (5%,10%,& 15%). DME [CH3O CH3] is mostly commonly produced from natural gas. Also DME has a high cetane number and superior vaporization quality compare with diesel. So it is suitable to use in diesel engine for better performance of engine. For this experiment, Taguchi method is used for optimization. For this optimization, parameters are taken as % of DME, Injection pressure and Load. Injection pressure taken as 160bar,180bar,200bar &220bar. Load is taken as 1kg,4kg,7kg & 10kg. After an experiment, taguchi gives optimum result for lowest brake specific fuel consumption (BSFC) and higher brake thermal efficiency(btheffi) at 15% DME, 180bar injection pressure, 10kg load. It is also concluded that engine performance is mostly affected by Load and little the effect of injection pressure.
