摘　　要：在高原地区对1台4100QB-2柴油机燃用生物柴油与柴油不同掺混比的混合燃料进行了台架试验。分析了混合燃料的物性，根据其物性和掺混比计算出当量燃油消耗率。对比分析了柴油机燃用混合燃料的有效热效率、机械效率和负荷特性。试验结果表明，在高原地区，柴油中加入体积比为10％～30％的生物柴油，柴油机的经济性有明显改善。In the plateau, the blended fuel of biodiesel and diesel in different proportions was fueled on a 4100QB-2 diesel engine. The nature of blended fuel was analyzed, and the equivalent fuel consumption rate was calculated according to its nature and mixing ratio. At the same time, the effective thermal efficiency, the mechanical efficiency and the load characteristics of diesel engine were compared and analyzed when different blended fuels was fueled. The results show that diesel engine has better economy when it is fueled with diesel mixed with 10 percent to 30 percent of biodiesel.
