Comparative test 1
The samples were evaluated for anti-wear and anti-friction properties (experimental conditions: 392N, 75 ℃, 1200r/min, 60 min) according to SH/T0189-determination of anti-wear properties of lubricating oils (four-ball machine method), the experimental results being the plaque diameter, average coefficient of friction, the specific results being given in Table 3 below.
Table 3 table for evaluating abrasion resistance and antifriction properties
Remarks: the smaller the abrasive spot diameter and average friction coefficient, the better the abrasion resistance and antifriction of the oil product.
Comparative test 2
The friction reducing property of the oil product is evaluated by using an MTM instrument (micro traction friction tester, temporary test standard), the test temperature is 120 ℃, the time is 2 hours, the friction mode is the friction between a test ball and a test disc, the traction coefficient of a test sample is shown in table 4, and the test result is shown in the specification.
Table 4 antifriction property evaluation table
Remarks: the smaller the average traction coefficient, the better the antifriction performance of the oil product.
Comparative test 3
The engine test program VIE is an engine test developed for energy saving performance of engine oil, the test method is ASTM D8114, the test is divided into two stages, and the two stages are respectively evaluated for energy saving effect. The index FEI SUM is the SUM of the two phase fuel economy improvement percentages, and FEI2 is the second phase fuel economy improvement percentage. This test was expensive, and thus only example 6 and comparative examples 1 and 2 were selected for the procedure VIE test, and the results are shown in table 5.
Table 5 energy saving performance evaluation table
Remarks: the higher the fuel economy improvement percentage value, the better the energy saving performance of the oil product.
Finally, it is noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be understood that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
