What are the magical effects of graphene as an additive in engine oil?

As the domestic automobile culture is still not mature enough, many people's car concept still stays in the car is "expensive", need to be careful "care" state, thus creating a lot of incorrect car concept, such as "high speed harms the machine ", "up shift to save fuel", "slow speed to save fuel" and so on.

In this kind of environment, there are more and more "tonics" in the market, especially the variety of oil additives, and there are countless people! Today, let's talk about what the oil additive is.

The popular oil additives currently on the market are broadly divided into two categories - detergents and antiwear agents. Cleaners rarely run long hours in the engine and are only used as a thorough cleaning before changing the oil. But the anti-wear agent is not the same. It plays a very important role: For example, when we wash clothes, it is difficult to wash only when washed with water, but after using the detergent, the clothes can be bright and new. For engine oil, the base oil is equivalent to water, and the additive is equivalent to detergent. The lubrication and protection ability of certain oil depends largely on the quality of the additive.

How to improve the lubrication ability has always been the focus of research on major oils and additives manufacturers. At present, the most mainstream anti-wear additives use active metals (such as zinc, molybdenum, etc.) with phosphorus and other oxidants to achieve the fineness of the friction surface. The effect of the gully fills in, thus reducing the resistance.

With the development of science and technology, especially the improvement of graphene technology in recent years, graphene additive technology has entered the field of lubricating oil. From a technical point of view, the lubrication principle of graphene is not exactly the same as that of the previous anti-wear additive. Since the molecular particles of graphene are very small, it can produce balls when rubbing between the cylinder wall and the piston. The effect is to turn the sliding friction into rolling friction, and at the same time smooth the unevenness of the cylinder wall like putty.

For example, under the action of graphene oil, it is like pushing a large stone (piston) on the ground full of balls and splashing oil. In this case, there is no difference in the friction of the balls. Isn't the complicated technology suddenly clear in the mind?

The use of graphene as an anti-wear agent can make low-viscosity oil more popular, thus helping cars to be more energy-efficient and environmentally friendly. But does it sound like the technology on such a high level is not with us? Not necessarily.

Recently, after a long period of research and development and testing, graphene engine oil produced by a lubricant company in Beijing has been on the market, which can reduce the friction coefficient and high temperature resistance. Moreover, China's graphene technology is at the world's leading level, and domestic graphene can meet the requirements.
