Mechanism of nano friction reducer oil additive

A large number of experimental studies have found that as an oil additive, nanoparticles can effectively improve the lubrication state of the friction pair and reduce friction and wear. It is an ideal friction-reducing oil additive. However, due to the limitations of modern science and technology and experimental conditions, the research on the anti-friction and anti-wear mechanism of nano oil additives is still in its infancy. Only through the combination of macroscopic phenomena and theoretical analysis, the means for a particular category of nano additives can be proposed. The theory is narrower. There are three primary speculations about its mechanism of action.

(1) The viewpoints of adsorption, permeation and tribochemical reactions. 

Nano oil additive can effectively fill the uneven surface of the friction pair and form a "third body" by tribochemical response with the character, thus having an anti-wear effect.

(2) The "Molecular Bearing" view.

Nano oil additive is small in size and ball-like, and can roll freely between friction pairs to reduce friction resistance, lower friction coefficient, and reduce wear;

（3）The viewpoint of nanofilm.

Organic modifiers are used when modifying nanoparticles. The organic matter with tribological properties moves to the surface of the friction pair and forms a nanofilm during friction. The nanofilm has high toughness and strong bending resistance, thereby enhancing the friction pair: the anti-wear performance and self-lubricating performance.

As a nanomaterial for the Nobel Prize in Physics in 2010, graphene, known as "black gold" and "king of new materials", has excellent strength, flexibility, electrical conductivity, thermal conductivity and ultra-thin properties.

Critical role of graphene as nano friction reducer oil additive

(1) The friction coefficient is only 0.01

When the lubricating oil rich in graphene elements is injected into the oil tank, the graphene sheets will adhere to the friction surface of the cylinder and piston ring walls under the action of van der Waals force. A layer of "graphene film" is formed. Due to its sheet structure, the friction between the original metal and the metal can be changed to the conflict between the graphene sheets, and the friction coefficient of graphene is only 0.01, so The friction can be significantly reduced.

(2) Penetration technology

The high-temperature and high-pressure environment derived from the internal combustion chamber of the engine and the friction generated by the high-speed movement will make the metal atoms of the engine and the graphite carbon atoms adhering to the metal surface inside the machine become extremely active. Then the "carburization" reaction occurs. The carburized metal friction surface will form a "carburized layer" protective film, which can significantly improve the hardness, wear resistance, fatigue strength and corrosion resistance of the engine friction metal surface. To achieve the effect of significantly extending the service life of the engine.

Why does graphene lubricant save fuel?

（1）The graphene protective film formed by the graphene lubricating oil on the friction surface reduces the friction loss of the engine. The reduction of friction loss means the increase of the engine output power, which means that the fuel is saved under the same power output.

（2）The graphene protective film formed by the graphene lubricating oil between the engine cylinder and the piston is working. The graphene protective film here improves the tightness of the combustion chamber and burns more fully. The carbon monoxide, hydrocarbons, etc. in the exhaust gas Fully burned to form carbon dioxide and water. Carbon dioxide is an inevitable substance after combustion. It is not a pollutant component in the exhaust gas. The exhaust gas is naturally purified. At the same time, due to the sealing of the combustion chamber, the high temperature and high-pressure gas in the combustion chamber affect the engine lubricating oil pan. The oxidation and acid corrosion of the lubricating oil, and the oxidation of the lubricating oil is one of the main reasons for the failure of the lubricating oil. The oil change cycle of the oil is naturally extended to reduce friction, reduce noise, and extend the life of the engine and camshaft.
