摘要
对生物柴油-柴油混合燃料的表面张力、运动黏度、抗磨性、氧化稳定性以及碳烟排放等特性进行了测试和研究。结果表明,生物柴油-柴油混合燃料的表面张力随生物柴油含量的增加呈抛物线趋势变化,并随温度升高呈幂函数曲线下降。生物柴油的磨斑直径小于柴油,最大卡咬极限压力大于柴油。生物柴油的质量分数为40%～70%,混合燃料的氧化稳定性明显提高。混合燃料的黏度随生物柴油质量分数的增加而线性增加,碳烟排放则显著下降。
The surface tension,kinematic viscosity,abrasion resistance,oxidation stability and soot emission characteristics of a biodiesel-diesel blend fuel were investigated.The results showed that the surface tension of the blend fuel varies in terms of parabola trend with the increase of biodiesel content and decreases according to a power function with the increase of temperature.The biodiesel exhibits less wear spot diameter and greater maximum bite limit pressure than the diesel fuel.The oxidation stability of the blend fuel is improved obviously when the biodiesel content is 40%~70%.With the increase of the biodiesel content,the viscosity of the blended fuel is increased linearly,while the soot emission,when burned as the engine fuel,is decreased significantly.
