Embodiment 1

[0008] Embodiment 1, the engine lubricating oil with self-cleaning function in this embodiment includes lubricating base oil and submicron copper powder dispersed in the lubricating base, and the mass ratio of the submicron copper powder and lubricating base oil is 1: 100, of course, the mass ratio of submicron copper powder to lubricating base oil can be other values ​​in the range of 0.1-8:100 in specific implementation; the diameter of the submicron copper powder is 0.1-5.0 microns.

Embodiment 2

[0009] Embodiment 2, the engine lubricating oil that this embodiment has self-cleaning function, comprises lubricating base oil and submicron copper powder dispersed in lubricating base, the ratio of the mass of described submicron copper powder and lubricating base oil is 2.5: 100. The diameter of the submicron copper powder is 0.1-5.0 microns.

Embodiment 3

[0010] Embodiment 3, the engine lubricating oil with self-cleaning function in this embodiment includes lubricating base oil and submicron copper powder dispersed in the lubricating base, and the mass ratio of the submicron copper powder and lubricating base oil is 4: 100. The diameter of the submicron copper powder is 0.1-5.0 microns.

[0011] The engine lubricating oil with self-cleaning function in the above-mentioned embodiments one to three can be prepared by the following method:

[0012] (1) Add sub-micron copper powder and deionized water to form a slurry with a concentration of 110-150g / L. After standing for 90-120 seconds, take the above slurry and separate and remove it by suspension separation and filtration and sieving. Large copper powder particles in submicron copper powder, so that the particle size and diameter are 0.5 to 3 microns;

Abstract

The invention discloses engine lubricating oil with a self-cleaning function. The engine lubricating oil comprises basic lubricating oil and sub-micron copper powder, wherein the sub-micron copper powder is dispersed in the basic lubricating oil; the weight ratio of the sub-micron copper powder to the basic lubricating oil is (0.1-8):100; and the diameter of the sub-micron copper powder is 0.1-5.0 microns. According to the engine lubricating oil with the self-cleaning function, the sub-micron copper powder is added to the basic lubricating oil, so that millions of sub-micron copper powder particles are uniformly distributed in every liter of the engine lubricating oil; in addition, the sub-micron copper powder can be used for polishing a friction surface under the driving of the moving friction surface, so that harmful substances, namely deposited carbon, a paint film, oil sludge and the like which are accumulated on the friction surface, can be effectively removed, the engine output power can be enhanced, the replacement period of engine oil can be prolonged, and the maintenance cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to an engine lubricating oil with self-cleaning function. Background technique [0002] As the lubricating oil is affected by the combustion temperature of the fuel and catalyzed by various media and metals during the engine operation, it will gradually deteriorate and age, and produce various substances harmful to the engine such as carbon deposits, paint films, and sludge. These harmful impurities are respectively Produced in different parts of the engine, and will gradually deposit on the oil passage and friction surface, resulting in poor lubrication and accelerated engine wear, endangering the normal use of the engine at all times, so it is necessary to remove carbon deposits, paint films and sludge on the friction parts of the engine in time harmful materials. [0003] However, the lubricating oil in the prior art does not have the ability to remove carbon deposits, p...
