The test conditions were:
temperature: 80 ℃; loading: 200N; frequency: 50 Hz; amplitude: 1.0 mm; the operation period is as follows: and 2 h.
The experimental group and the control group were analyzed under the above test conditions, and the results are shown in table 1 below.
TABLE 1SRV test results
| Group of | |
Experimental group 2 | |
Control group 2 |
| Average coefficient of friction | 0.070 | 0.072 | 0.079 | 0.081 |
| Abrasive spot diameter, mm | 0.402 | 0.405 | 0.594 | 0.605 |

Meanwhile, the diameter of the wear scar of the oil product is superior to that of the common commercially-sold oil, which shows that the engine oil disclosed by the invention realizes energy conservation and also improves the wear resistance of the oil product to a certain extent.
3 viscosity-temperature property
Indexes such as kinematic viscosity at 100 ℃, viscosity index, low-temperature dynamic viscosity, low-temperature pumping viscosity and the like are adopted to evaluate the viscosity-temperature performance of the low-viscosity high-efficiency energy-saving engine oil. Kinematic viscosity is an index used for reflecting the internal friction of an oil product and representing the oiliness and the fluidity of the oil product. The viscosity index reflects the degree of the oil viscosity changing along with the temperature, and the higher the viscosity index is, the smaller the influence of the temperature on the viscosity is, and the better the viscosity-temperature property is. The low-temperature dynamic viscosity is closely related to the starting performance of the engine at low temperature, and if the engine oil is too viscous at the starting temperature, the moving parts are viscous, so that the crankshaft of the engine cannot rotate to reach the specified rotating speed and cannot be started. The low-temperature pumping viscosity reflects the capability of engine oil to be continuously and fully supplied to an oil pump inlet at low temperature, and the phenomenon of air entrainment and evacuation is easily caused when the viscosity is too high, so that the oil cannot flow to the pump inlet, and the starting abrasion is caused. The results obtained are shown in table 2 below.
TABLE 2
As can be seen from Table 2, the viscosity index of the low-viscosity high-efficiency energy-saving engine oil can reach more than 210, the low-temperature dynamic viscosity of the low-viscosity high-efficiency energy-saving engine oil is obviously superior to that of a commercially available oil product, and the low-temperature pumping viscosity of the low-viscosity high-efficiency energy-saving engine oil is superior to that of the commercially available oil product, so that the low-temperature pumping viscosity of the low-viscosity high-efficiency energy-saving engine oil is excellent in viscosity.
4 energy saving and improving effect
The fuel economy test oil results are shown in figure 2. As can be seen from FIG. 2, the experimental group 1 of the present invention showed a good fuel economy improvement effect with respect to Toyota 0W-20, and the fuel economy could be improved by 1.0%.
The above tests were repeated for engine oils compatible with LSPI low speed pre-ignition prevention performance obtained in other embodiments of the present invention to arrive at the same test conclusions, not to mention them.
Although the invention has been described in detail hereinabove with respect to a general description and specific embodiments thereof, it will be apparent to those skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
