Zhang Yu is also thinking about researching several pieces of machinery and equipment that he has recently conceived.

After designing the electric energy optimization machine, after Xiao Lao's inference, Zhang Yu suddenly thought that although the current main energy source has begun to be converted into electric energy.

But for now, the main energy source of the automotive industry is gasoline, and some special industries use gasoline engines.

Since the electric energy optimization machine can be designed, it is natural to design a gasoline engine, you must know that the world's most tense energy sources, coal, oil, has been high.

Who can master these precious energy, will grasp the world's right to speak, oil as the main energy source of gasoline engines, if Zhang Yu can design a gasoline engine that greatly saves oil.

Once this product comes out, you don't have to think about it, it will definitely be a sensation in the entire market.

A gasoline engine is an engine that uses gasoline as fuel to convert internal energy into kinetic energy.

Because gasoline is less viscous and evaporates quickly, gasoline can be injected into the cylinder with a gasoline injection system, and after compression reaches a certain temperature and pressure, it is ignited with a spark plug to make the gas expand to do work.

The gasoline engine is characterized by high speed, simple structure, light weight, low cost, stable operation, and convenient use and maintenance.

In response to these data, Zhang Yu started from the aspect of high speed, and began to improve, without affecting the quality, cost, and smooth operation, how to increase the speed, which is really what Zhang Yu needs to study at present.

Thinking of these, Zhang Yu began to get busy, and with the experience of designing an electric energy optimization machine, the process of designing a gasoline optimization machine will be smoother.

The general principle is unchanged, the most important point is how to change the use of energy, which involves very complex things, Zhang Yu needs to carefully study thoroughly, and design all the sketches before he can start production.

Li Shengping, on the other side, was also busy with his diplomatic work, Zhang Yu looked at the computer, and drew on A4 paper from time to time, and drawings were the most basic things.

At the same time, it is also something that must be figured out at the beginning of a product, so to speak, as long as there are drawings, basically the product is made.

Of course, the manufacturing industry behind also requires very advanced technology, and Zhang Yu is the kind of person who has both the ability to make drawings and advanced machine technology.

The things that Luban Craftsman brought to Zhang Yu are too rich, Zhang Yu has only developed two functions so far, the first is about the craftsman spirit into the body, his own machine scientific research technology, instantly rise a level, design the machine, and get twice the result with half the effort.

As for the other function, it is incomparably rich in knowledge, and Zhang Yu is still developing the knowledge behind the Luban craftsman.

At present, although these two functions are enough for Zhang Yu to use, what about building a business empire in the future?

It is said that it is easy to fight the world, but it is difficult to defend the world, and the same is true in business, just like now Zhang Yu's R&F Group has begun to develop, on the surface, although there are no companies to attack Zhang Yu's R&F Group.

But secretly, because of the various convenient machines developed by Zhang Yu, their interests were involved, and they hated Zhang Yu very much.

Now the part of the performance is only in the eastern province, as Zhang Yu R&F Group is getting bigger and bigger, his products have begun to be promoted to all over the world.

There will be more and more interest lines involved, and they will never let Zhang Yu develop like this, and Zhang Yu will only offend more enemies in the future development.

Before these forces are suppressed, Zhang Yu must first become strong, which is also a question that Zhang Yu only figured out after returning from the boutique machinery and equipment exhibition.

Participating in the exhibition by himself is just a very common move, but because he stole the limelight from others, he attracted hostile eyes.

This is just that it has not violated the line of interests, if Zhang Yu infringes on their line of interests, it is conceivable how these companies will attack Zhang Yu's R&F Group.

Thinking of these, Zhang Yu couldn't wait to start developing the machine, in addition to the gasoline optimization machine, Zhang Yu also planned to design a few more products, just a product, the development of a product, or a little slow.

It just so happens that the current development of R&F Group is quite good, and it also has the ability to promote several products in a row.

The idea flashed away, and then it needed to be realized step by step, and after the drawings of the gasoline optimizer were designed, it was time to get off work.

"Zhang Yu, don't leave yet, look at your busy day today, what are you painting?" Li Shengping stretched.

Zhang Yu turned his head away, and couldn't help but secretly think in his heart, this girl, is she trying to tempt me? Can you not stretch your waist here?

Li Shengping also seemed to realize something, and quickly put down her hand, her face was red, her mind was clouded, and she didn't know what she was thinking, she made this move, but it was very casual, forgetting that Zhang Yu was still here.

"Get off work, rest early, and combine work and rest. Will Zhang Yu feel that he is that kind of woman, Li Shengping thought a lot in his heart, and Zhang Yu on the other side turned around and behaved lightly.

Li Shengping saw Zhang Yu's flat expression, so he came back to his senses, looked at Zhang Yu, nodded, and packed his things absentmindedly.

"Shengping, I may have been a little busy lately, about the matter of agreeing to play with you, if we don't go out for a walk tonight, we may not have much time in the future. In order to alleviate the embarrassment, Zhang Yu brought up what he said before.

"Okay!" Li Shengping nodded again like a well-behaved rabbit.

"Waiting for you outside. Seeing that Li Shengping agreed, Zhang Yu stood up, put away the drawings on the desk, and walked towards the outside of the office.

Li Shengping just smiled back, the action of cleaning up things was a little faster, and he tidied up casually, not at all as careful as a girl.

She was overjoyed, took her small bag, and walked out quickly, Zhang Yu had already gotten into the car at this time and waved at Li Shengping.

Li Shengping got into the car, and with the start of the car, he drove out of the door of R&F Group.

When the security guard at the door saw this scene, there was a strong envy in his eyes, you must know that he was the security guard of the R&F factory at the beginning, and then the security guard of the R&F Group, and now the security guard of the famous enterprise R&F Group, he is the one who witnessed Zhang Yu from existence to nothing.

Now that I see that Zhang Yu has been defeated and there are people, this is simply the pinnacle of life for these little people, of course, Zhang Yu is not a small person, but a real big person.

The security guard's salary here has also increased a lot, and when the upper level changed, the security guard also left R&F Group, but he didn't have any ability, and after some thought, he finally stayed, which became a more important decision in his life.
