Performance of Single Cylinder DI Diesel Engine: Varied Compression Ratio Fueled with Blends of Ethanol

摘要

In present experimental investigation 3.75 kW diesel engine AVI Single Cylinder water cooled, Kirloskar Make tested for blends of diesel with ethanol. Tests were conducted for three different compression ratios. Engine test setup was developed with moving cylinder head for variation of compression ratio to perform investigations using these blends. The engine performance studies were conducted with rope break dynamometer setup. Parameters like speed of engine, fuel consumption and torque were measured at different loads for pure diesel and for blends of diesel with ethanol at different compression ratio. Break Power, BSFC, BTE and heat balance were evaluated. Paper represents the test results for blends 5% to 20% and three different compression ratios.
