摘要：In this investigation the viscosity of cottonseed oil, which has been considered as an alternative fuel for the compression Ignition (C.I) engine was decreased by blending with diesel. The blends of varying proportions of cottonseed oil and diesel were prepared, analyzed and compared with the performance of diesel fuel and studied using a single cylinder C.I. engine. Significant improvement in engine performance was observed compared to neat cottonseed oil as a fuel. The brake thermal efficiency, specific fuel consumption, volumetric efficiency, peak cylinder pressure, smoke, CO, HC, NO and the exhaust gas temperatures were analyzed. The tests showed increase in the brake thermal efficiencies of the engine as the amount of diesel in the blend increased. The volumetric efficiency of the engine also increased when compared with that of neat cottonseed oil and the exhaust gas temperature with the blends decreased. The smoke, CO and HC emissions of the engine ware also less with the blends. From the engine test results it has been established that 20–40% of cottonseed oil can be substituted for diesel without any engine modification as a fuel.
