棉籽油作为压燃式发动机的代用燃料，通过与柴油掺混，降低了棉籽油的粘度。本文制备了不同比例的棉籽油与柴油的混合燃料，并对混合燃料的性能进行了分析比较。发动机与纯棉籽油作为燃料相比，观察到发动机性能的显著改善。分析了发动机的制动热效率、燃油消耗率、充气效率、峰值缸压、烟度、CO、HC、NO和排气温度。试验表明，随着混合物中柴油量的增加，发动机的制动热效率增加。与纯棉籽油相比，掺混棉籽油的发动机充气效率提高，排气温度降低。柴油机的烟度、CO和HC排放也有所降低。根据发动机试验结果，已经确定20-40%的棉籽油可以代替柴油作为燃料，而无需对发动机进行任何改造。版权所有© 2011国际能源与环境基金会保留所有权利。
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.
