摘要
用红外光谱分析法测定了CF-4 15W/40润滑油台架试验和行车试验油样的氧化值、硝化值、硫化值,并将台架试验油样的氧化值、硝化值及硫化值进行加和与酸值增值进行相关性研究,通过研究得出了这三者之和与酸值增值之间的相关性模型,并通过CF-4 15W/40润滑油在柴油车辆和固定式柴油发动机上的试验油样数据(氧化值、硝化值及硫化值之和与酸值增值)进行相关性验证,结果表明通过理论计算得出的酸值增值与实际测定的酸值增值具有一定的相关性,说明用红外光谱法测定的氧化值、硝化值、硫化值进行加和得到的氧硝硫值代替实际测定的酸值增值在理论上是可行的。
The oxidation, nitration, sulfation of CF- 4 15W/40 lube oil for bench test and field test were measured by FTIR. It was studied on the relativity between the additions of oxidation, nitration, sulfation and the increments of acid number from the bench tests, and the relativity model was deduced. Then the relativity model was verified with the obtained data from the field tests. The results showed that the relativity is good, and it is theoretically feasible that the additions of oxidation, nitration, sulfation by FTIR substitute for the increments of acid number by GB/T 7304.
