Traditional oil film

The biggest wear and tear of automobile engine is actually at the moment of cold car system. Relevant experiments have confirmed that the wear caused by the engine five minutes before the cold start is equivalent to normal driving 10000 km.

Let's give an example to explain why some private cars have engine oil when they drive 65,438+200,000 kilometers, while our taxis are generally 800,000 to 1 10,000, so it is unlikely to burn engine oil. Why? The main reason is that there are fewer dry rubbing times when the cold car is started. Generally, our taxis can only start once every day. Even some models haven't started cold, and they have been working in two or three shifts, while private cars are left overnight and used again the next day, and the cold cars are started again.

When the cold car starts, there is a phenomenon in tribology called lack of oil lubrication. That is, the engine oil started by the cold car sinks into the oil pan of the engine due to gravity. At the moment of ignition, engine oil can not effectively lubricate all parts of the engine, and it can only be lubricated after the oil pump has pumped out the relevant parts. The first three generations of engine oil, that is, mineral oil or synthetic oil used now, are all lubricated by oil film. Friction can only be reduced under the action of oil film. Therefore, the use of any engine oil in the past can not effectively solve the oil-deficient lubrication state of cold start. Even if Jia Mouduo's protection didn't start first, it was commercial propaganda, because. There is no experiment to prove that using Camodo will not lead to dry friction or increase the service life of the engine.

The use of the fourth generation engine oil can effectively improve the dry friction of cold car starting, and the experiment proves that it can effectively reduce 70%. Its principle is to improve the surface smoothness of friction pairs.

The key laboratory of national defense tribology of Yanshan University conducted a perfect comparative experiment on the whole fourth generation lubrication technology and additives. The friction coefficient decreased from 0. 12 to 0.04.

Experimental conditions: spring steel and vermicular graphite cast iron simulate engines.

Compare different American products and additives.

The lean oil lubrication experiment was also carried out. It further proves the horror of reducing friction under the condition of lack of lubricating oil during cold start.

Lock for 4820s when oil is exhausted, and use additives.

The friction temperature of the fourth generation lubrication technology additive Ifeit decreased obviously after use. It turns out that friction will be reduced.

In the past two days, fans have been asking me if I can reduce carbon emissions or improve engine power. This is of course, because after effectively reducing friction, the engine's own resistance is reduced, so its thermal efficiency is also improved. Moreover, after the coating is formed, the cylinder pressure increases, and the combustion will become full after the cylinder pressure increases, so this is a series of reactions. Of course, as the fourth generation engine oil, it is not only a surface, but also a technology. It has related experiments. Let you see, this is a revolution that subverts the whole lubricating oil technology.

The fuel saving rate and tail gas improvement are very obvious.

In the future, the fourth generation of engine oil will definitely replace the traditional first three generations of engine oil, and even the three major American shell brands have not yet been put on the market. In the prior art, because there are two invention patents here. Also held. Invention patents are protective and cannot be used by other companies. This is a revolution in lubricating oil.

The vehicle used completely solved the problem that the engine is getting older and more expensive, and solved the confusion of a car owner. The owner is worried about the quality of the added oil, which could not be identified before. However, the obvious effect of using the fourth generation engine oil for 5 minutes is to reduce engine friction and noise. At the same time, it saves fuel and improves power. It feels like a new car. But also can obviously improve tail gas combustion. Save maintenance money with the fourth generation oil. Afraid of wasting engine oil, use the fourth generation engine oil.

Everyone pays attention to the 60-second brother and the revolution of engine oil, so that more car owners can improve their power by saving fuel and save the maintenance money back. But also reduces the cold start wear and prolongs the service life of the engine.
