Embodiment and the resistance coefficients of each time phase of each embodiment, the greasy property of lubricating oil its resistance the best is the least, sends out
Motivation power per liter will be the strongest；Otherwise resistance is the biggest, power per liter will reduce, and power will reduce, and oil consumption will increase.From figure
In it can be seen that comparative example's frictional resistance is along with using the increase of time to become big, on the contrary, the friction resistance of embodiment 1～5
Power diminishes along with the increase of the time of use, subtracts along with the increase removing valency electron modified graphene content in lubricating oil simultaneously
Little.The mechanical movement resistance removing valency electron modified graphene is the least, embodies the energy-efficient performance of its excellence.
Fig. 3 is comparative example and each embodiment coefficient of friction oscillogram in use, embodies contrast and implements
Example and the coefficient of friction of each time phase of each embodiment, coefficient of friction is the biggest, and the abrasion of electromotor is the biggest, and service life is more
Short, on the contrary coefficient of friction is the least, and service life is the longest.It can be seen that the coefficient of friction of comparative example is along with the time
Increase become larger after tend towards stability, when 13 minutes, its coefficient of friction reached 0.149 μ, and the friction of embodiment 1～5
Coefficient increases over time after tapering into and tends towards stability, along with the increase removing valency electron modified graphene content in lubricating oil
Coefficient of friction tapers into, when 15 minutes its coefficient of friction be respectively 0.1454 μ, 0.145 μ, 0.1441 μ, 0.1432 μ,
0.1422 μ, it is seen that go the greasy property of valency electron modified graphene lubricating oil higher than without going valency electron modified graphene to lubricate
Oil.
Fig. 4 is comparative example and each embodiment volatilization oscillogram in use, intuitively embodies contrast and implements
Example and the volatilization value of each time phase of each embodiment, the volatilization value of lubricating oil is the highest, the greasy filth carbon distribution that engine interior produces
Will be the most, the consumption of lubricating oil will be the most.It can be seen that comparative example's volatilization value is along with the increasing of the time of use
Adding and become big, on the contrary, the volatilization value of embodiment 1～5 is slowly increased along with the increase of the time of use, tends to steady after 10 minutes
Fixed, reduce along with the increase removing valency electron modified graphene content in lubricating oil, it is seen that remove valency electron modified graphene simultaneously
The energy-efficient performance of lubricating oil is higher than without removing valency electron modified graphene lubricating oil.
Finally illustrate, preferred embodiment above only in order to technical scheme to be described and unrestricted, although logical
Cross above preferred embodiment the present invention to be described in detail, it is to be understood by those skilled in the art that can be
In form and it is made various change, without departing from claims of the present invention limited range in details.
