中文摘要:
      目的 研究低黏度0W-16机油的减摩性能。方法 选取3种减摩剂MoDTC、GMO和油酸酰胺,分别按一定比例加入到0W-16基础油中,获得单剂油样,并选取2种0W-16全配方机油(A-1油和A-2油),利用SRV-IV试验机测试润滑油样的减摩性能和极压性能,利用傅立叶红外光谱仪和油料元素光谱分析仪分析机油油样结构,并利用3D光学表面轮廓仪表征缸套块磨痕形貌。结果 对于单剂油样,0W-16基础油分别加入MoDTC、GMO和油酸酰胺后,平均摩擦系数由0.198分别减小到0.088~0.116、0.167~0.178和0.179~0.194,缸套块磨痕平均深度由3.59 mm分别减小到0.44~0.52 mm、2.11~2.24 mm和3.19~3.44 mm。对于0W-16全配方机油,在摩擦润滑试验低温区,A-1油比A-2油摩擦系数低,随着温度升高,A-1油和A-2油的摩擦系数进一步减小;摩擦润滑试验后,A-1油和A-2油的缸套块磨痕平均深度分别为0.13 mm和0.18 mm。在极压试验中,A-1油和A-2油的极压值分别为1500 N和900 N。结论 在0W-16基础油中分别加入3种减摩剂后,MoDTC的减摩和抗磨作用最好,油酸酰胺的减摩和抗磨作用最差。对于0W-16全配方机油,在摩擦润滑试验低温区,A-1油中的无灰减摩剂和MoDTC产生协同作用,表现出更低的摩擦系数;随着温度升高,A-1油和A-2油中的ZDDP与MoDTC产生协同作用,进一步降低摩擦系数。在极压试验中,A-1油中的ZDDP与其他添加剂产生协同作用,表现出更大的极压值。添加剂之间的协同作用对油品节能性能产生重要影响。
英文摘要:
      The work aims to investigate the friction-reduced property of 0W-16 low viscosity engine oil. Three kinds of friction modifiers MoDTC, GMO, and oleamide were respectively added into 0W-16 base oil to obtain oil sample with single friction modifier. Moreover, two kinds of fully-formulated low viscosity engine oil 0W-16 (oil A-1 and oil A-2) were selected. The friction-reduced property and extreme pressure property of the lubricating oil samples were tested by the SRV-IV tribometer. The compositions of fully-formulated engine oil samples were analyzed by FTIR spectormeter and oil element spectormeter. The wear scar of cylinder liner segment was analyzed by 3D optical surface profilometer. Compared with 0W-16 base oil, oil sample with single friction modifier of MoDTC, GMO and oleamide respectively had an average friction coefficient decreasing from 0.198 to 0.088~0.116, 0.167~0.178 and 0.179~0.194, respectively. The average wear scar depth of cylinder liner segments decreased from 3.59 mm to 0.44~0.52 mm, 2.11~2.24 mm and 3.19~3.44 mm, respectively. For the fully-formulated engine oil 0W-16, oil A-1 showed lower friction coefficient than oil A-2 in low temperature testing condition. When the testing temperature increased, the friction coefficients of oil A-1 and oil A-2 decreased further. The average wear scar depth of cylinder liner segments of oil A-1 and oil A-2 were 0.13 mm and 0.18 mm respectively after friction and lubrication test. The extreme pressure of oil A-1 and oil A-2 was 1500 N and 900 N respectively in extreme pressure test. When the base oil 0W-16 is blended with the three kinds of friction modifiers respectively, the oil with MoDTC shows the best friction-reduced property and anti-wear property, and the oil with oleamide shows the worst friction-reduced property and anti-wear property. For the fully-formulated engine oil A-1 in low temperature testing condition, there is a good synergistic effect between MoDTC and no-ash friction modifier, and oil A-1 shows lower friction coefficient. For the oil A-1 and oil A-2, when the testing temperature increases, ZDDP and MoDTC generate good synergistic effect and the friction coefficient decreases further. In the extreme pressure test, oil A-1 shows higher extreme pressure due to the good synergistic effect between ZDDP and other additives. The synergistic effects between additives have an important influence on the energy-saving property of engine oils.
