研究了基础油对四缸增压柴油机排放颗粒物特性的影响。这台发动机用了两种基础油(标号为150和350)。350基础油的粘度和闪点高于150基础油，采用透射电子显微镜、拉曼光谱和热重分析仪(TGA)对其粒径分布、纳米结构、石墨化度及其氧化特性进行了分析。在1200转/分和2000转/分时，150基础油的平均直径大于350基础油，一次粒子直径分布符合高斯分布。350基础油层间条纹长度较150基础油短，但分离距离和边缘弯曲较大。对于150基础油的石墨化程度，在1200rpm时，D_1带与G带面积的比值(AD1/AG)从1.4162降至1.0945，表明150基础油的颗粒结构比350基础油的颗粒结构更加有序，热重分析结果表明，150基础油的元素碳质量分数大于350基础油，而挥发分较少。
Effect of base oil on the characteristics of emitted particulate matter from a four-cylinder turbocharged diesel engine was investigated. This engine was lubricated with two kinds of base oil (characterized as 150 and 350). The viscosity and flash point of 350 base oil are higher than 150 base oil’s. Transmission Electron Microscope, Raman spectroscopy and Thermogravimetric analyzer (TGA) were employed to analyze the particle diameter distribution, nanostructure, graphitization degree and its oxidation characteristics. The primary particles diameter distribution conformed to Gaussian distribution, whereas the mean diameter of 150 base oil was larger than 350 base oil’s at 1200 rpm and 2000 rpm. The layer fringe length of 350 base oil was shorter than 150 base oil’s, while its separation distance and fringe tortuosity were larger. As to the graphitization degree of 150 base oil, the ratio of the D1band to G band areas (AD1/AG) decreased from 1.4162 to 1.0945 at 1200 rpm, indicating that the particle structure of 150 base oil was more ordered than 350 base oil’s. According to the TGA results, the elemental carbon mass fraction of 150 base oil was larger than that of 350 base oil, while the volatile fractions were less.
