Description: A comparative study was conducted to evaluate the effect of using PKO, pure petroleum diesel and their blends (B5, B10, B20, B30, B40, and B100), on the performance of a four-cylinder CI diesel engine (David Brown 990: 58hp; 2WD), at Farm Power and Machinery Test laboratory Centre (FPMTLC), Department of Agricultural and Bioresources Engineering, University of Nigeria, Nsukka. Each fuel test was performed using Heenan-Froude hydraulic dynamometer engine-test-bed for petroleum diesel (B0) and other blends. The objectives of the study were to determine the fuel consumption rates, energy expended, brake specific fuel consumption, and brake thermal efficiency, under varying operating speeds at constant torque. The variables calculated were analyzed and compared with each other in order to determine the differences in the engine performance and also to determine the optimum test fuel. The result obtained for fuel consumption rates were 0.7880911, 0.9259259, 0.7456504, 0.7887818, 0.8279669, 0.9443861, and 0.8035714l/h, for B0, B5, B10, B20, B30, B40, and B100 were respectively, while that obtained for brake specific fuel consumption were 0.1824417, 0.2143503, 0.1726168, 0.1826016, 0.1916729, 0.2186238, and 0.1860254l/KWh, for B0, B5, B10, B20, B30, B40, and B100 respectively. The overall result obtained showed that B10 (10% PKO biodiesel and 90% pure petroleum diesel) provided the lowest fuel consumption rate, lowest brake specific fuel consumption, and highest energy expended with a good thermal efficiency compared with other test fuels. Thus, B10 is the optimum test fuel and can be used as alternative fuel in David Brown 990 (58hp; 2WD) or similar CI diesel engines without any engine modification.
