As can be seen from Table 1, after four-ball machine experiment, engine profit that is anti-wear, saving fuel oil produced by the present invention
Wear scar diameter, the average friction coefficient of lubricating oil are smaller, illustrate that the antiwear and friction reduction property of inventive engine lubricating oil is good,
In, the antiwear and friction reduction property of embodiment 3 is best, is highly preferred embodiment of the present invention；Compared with comparative example 2-3, the present invention starts
The antiwear and friction reduction property of machine lubricating oil is more excellent.
Test example two, simulation of engine platform experiment
1, test material: engine lubricating oil prepared by embodiment 3, comparative example 1, comparative example 2, comparative example 3.
2, test method:
(1) before simulation of engine platform experiment, every friction of engine lubricating oil to be measured is tested on four-ball machine
Performance (film strength, sintering load, wear scar diameter and average friction coefficient) is learned, is then packed into engine to be measured within the engine
Lubricating oil to clean to engine interior, then bleeds off the engine lubricating oil in idle running 1 hour, dismantles engine
Cylinder head, cylinder block and piston, with petroleum ether cleaning piston ring, after drying on assay balance test experiments secondary piston ring weight
Amount；
(2) when simulation of engine platform experiment, it is packed into new engine lubricating oil to be measured within the engine, opens rack,
Test engine per 100 km oil consumption idle under a fixed load (is run 10 hours, fuel consumption under a fixed load
It is obtained by gasoline reduction amount in measuring cup test oil bottle)；
(3) after simulation of engine platform experiment, engine lubricating oil and piston ring are taken out, hair is tested on four-ball machine
Every tribological property (film strength, sintering load, wear scar diameter and average friction coefficient) of motivation lubricating oil, uses petroleum ether
Cleaning piston ring, after drying on assay balance piston ring weight after test experiments, to calculate piston ring in platform experiment
Abrasion loss.New cylinder block, piston and piston ring are finally changed, engine is assembled, tests next group of engine oil, process
Ibid.
3, test result is as shown in table 2, table 3.
Table 2: the comparison of tribological property Parameters variation before and after simulation of engine platform experiment
As can be seen from Table 2, before simulation of engine platform experiment, it is prepared by the present invention it is anti-wear, save fuel oil and start
Film strength, the sintering load of machine lubricating oil are higher, and wear scar diameter is lower, and it is excellent that this illustrates that inventive engine lubricating oil has
Different extreme pressure and antiwear behavior, compared with comparative example 1-3, engine lubricating oil of the invention has better extreme pressure and antiwear behavior.
Compared with comparative example 1-3, after simulation of engine platform experiment, engine lubrication that is anti-wear, saving fuel oil prepared by the present invention
Film strength, wear scar diameter, the reduction amplitude of oil are smaller, and average friction coefficient variation is smaller.It can be seen that produced by the present invention
The service life of machine oil can be improved in engine lubricating oil, to extend drain period when machine oil uses on the engine.
Table 3: the comparison of piston ring scuffing amount in simulation of engine platform experiment
| Project | Embodiment 3 | Comparative example 1 | Comparative example 2 | Comparative example 3 |
| Compression ring abrasion loss (mg) | 4.76 | 5.63 | 5.34 | 6.25 |
| Oil ring abrasion loss (mg) | 1.45 | 1.94 | 1.72 | 2.18 |
| It amounts to (mg) | 6.21 | 7.57 | 7.06 | 8.43 |
As can be seen from Table 3, compared with comparative example 1-3, engine lubricating oil produced by the present invention can reduce engine
The abrasion loss of piston ring, therefore, engine lubricating oil produced by the present invention can improve the internal lubrication of engine, and extension is started
The service life of machine.
Test example three, driving experiment
1, test material: engine lubricating oil prepared by embodiment 1, embodiment 2, embodiment 3, comparative example 2, comparative example 3.
2, test method:
The engine for taking plain oil, embodiment 1, embodiment 2, embodiment 3, comparative example 2, comparative example 3 to prepare respectively
Lubricating oil, the oil consumption on the automobile for using the same model of same producer, in test driving experiment.In regulation section (without red green
Lamp, driving vehicle are few, face is smooth) on the oil consumption after certain mileage is travelled with the speed of 70km/h.
3, test result:
Test result is as shown in table 4.
Table 4: the oil consumption in driving experiment is compared
As can be seen from Table 4, compared with plain oil, comparative example 2-3, the hundred of engine lubricating oil produced by the present invention
Gas mileage is lower, wherein the fuel consumption per hundred kilometers of embodiment 3 is minimum, rate of economizing gasoline highest, is highly preferred embodiment of the present invention.By
This is as it can be seen that inventive engine lubricating oil can significantly reduce the fuel consumption of engine.
