Performance characteristics; fuel power (FP), brake thermal efficiency (BTE), brake power (BP) and Specific fuel consumption (SFC) of blended (petrol/bio-ethanol) fuels were studied and compared with neat petrol. The blends were; E05, E10, E15 and E20 for 5%,10%, 15% and 20% bio-ethanol respectively. The performance parameters were measured based on short standard engine tests performed on a Cortina petrol engine test bed, a four stroke engine, and variable speed SI engine with an eddy current dynamometer and Tachometer. The result showed that E05 and E10 were the optimum blending ratios for bioethanol and petrol. It can be concluded from these results that E05 and E10 are the most suitable blends for use in four stroke SI engines.
