Spring Breeze 1991

With Yao Yuan's capital injection, Zhongshen's Zuo Dawang's 125cc two-stroke engine developed smoothly, and there was no problem in reaching mass production within the specified time.

Yao Yuan does not intend to use motorcycle development as the main business of steering machinery, so he will not take the job of King Zuo.

However, the 150cc two-stroke engine is critical to getting the steering machine off the ground.

It is related to the success or failure of Xiangfang Machinery's first product to be launched.

Zhan Chenggui and Yuri greeted each other, and they got along well. One was working hard to learn Russian, the other was working hard to learn Chinese, and both were trying to solve the communication barrier.

When I came to a shelf, there was an engine like a transformer on it, and the shape was relatively neat. This is the key, which shows that Zhan Chenggui fully considered the overall design factors of the future finished product when designing.

As far as this is concerned, Yao Yuan expressed his satisfaction, and the previous ten thousand warnings seemed to have worked.

Then look at the workmanship, there are so many precision machine tools, and there are master craftsmen hired from large state-owned factories. In addition, there are two senior skilled workers from the former Pilsen Machinery Factory in Yuri's team, who use imported materials. Block impeccable.

It is more appropriate to say that it is a work of art.

Zhan Chenggui began to introduce, "We have done a lot of tests, the power has reached 9.5 kilowatts, the maximum torque is 11 Nm, and the total service life is 12000 hours, which fully exceeds the technical indicators you proposed. Mr. Yao, the product has reached the mass production standard. .”

After he finished speaking, his chin was raised slightly, which was rare, very proud.

Yao Yuan was very surprised. He frowned and said, "The power has reached 9.5 kilowatts? The maximum torque is 11 Nm?"

"Yes." Zhan Chenggui pointed to Yuri, "Comrade Yuri, please introduce the detailed technical parameters and the technology we adopt to Mr. Yao in detail."

Yuri came as soon as he opened his mouth, speaking so fast that even Chen Mingliang couldn't quite understand it, but when he looked at Yao Yuan, he seemed to understand it easily.

After talking for about ten minutes, Yuri finished speaking.

Yao Yuan said dumbfoundedly, "You have adopted EFI technology, don't tell me that the gasoline you used for the experiment was refined twice."

"Yes, Mr. Yao, just for EFI technology, I think this product has fully met your requirement that more than 90.00% of the technology is self-developed." Yuri laughed, "In order to maximize the excavation For the data of the engine, we conducted secondary purification on the gasoline sold on the market, and finally tested the two largest technical parameters of 9.5 kW and 11 Nm."

He is proud.

After 20 years, the 150cc engine developed by Zongshen is only 8.5kW and 10Nm, of course they can be proud of it!

Yao Yuan is really convinced of Zhan Chenggui and Yuri. These two geeks who have not yet become famous, the reason why they will become famous in the future is really not out of thin air. Look, they have shown amazing abilities now !

The use of EFI technology can improve the efficiency of fuel utilization, fuel combustion is more complete, and of course the power can be increased!

"You guys actually came up with EFI technology..." Yao Yuan shook his head with a wry smile, and almost didn't spit it out.

Zhan Chenggui said with a smile, "Mr. Yao, I told Comrade Yuri that this is a surprise for you. This EFI technology belongs to us."

Chen Mingliang hastily added, "Mr. Yao, the EFI technology has been submitted to the patent legal department. First apply for domestic patents and then apply for foreign patents."

It is Yao Yuan's rigid requirement to apply for a new technology as soon as it comes out.

The two legal teams under He Xueli are also the legal team of Spring Breeze Academy of Sciences.Yao Yuan personally served as the dean of the Spring Breeze Academy of Sciences, and his team naturally became the administrative management team of the dean of the Spring Breeze Academy of Sciences.

Yao Yuan recalled for a while, and said, "The mass-produced motorcycles of Honda and Suzuki seem to use carburetors, right?"

"This is the case at present, so Mr. Yao, once our engine is put into commercial use, it will definitely lead the technological trend of motorcycles!" Zhan Chenggui said enthusiastically, his eyes were shining.

Yao Yuan still shook his head and smiled wryly, and asked, "Is it open-loop EFI or closed-loop EFI?"

One question reflects Yao Yuan's ability in technology.

Yuri couldn't help asking, "Mr. Yao, do you also have research on electronic technology?"

Yao Yuan waved his hand and said, "I still understand the principle, although I'm not proficient. You are engaged in electric injection, how can the ECU solve it?"

The core of EFI technology is the electronic control unit, that is, ECU. Yao Yuan vaguely remembers that the first domestic car equipped with EFI engine was launched after 2002.

The best ECU manufacturer in the world is Bosch, and most of the cars in later generations use their products, occupying a monopoly position.

But a motorcycle with an EFI engine...

If it weren't for the country's stricter and stricter emission control later, I am afraid that few manufacturers are willing to adopt this technology.

Because the advantages of EFI technology are placed on motorcycles, there is actually no obvious difference in effect.EFI technology is used, fuel saving, less noise, easy to start, etc. However, in the case of technological progress, the use of carburetor engines can also do well in these aspects.

However, a motorcycle with an EFI engine is much more expensive.

A Suzuki original 125cc men's motorcycle costs tens of thousands of yuan, and a 125cc men's motorcycle manufactured by Qingqi Factory is exactly the same, but it uses a carburetor engine. It only costs 4000 yuan, and the price difference is more than half.

Yuri was a little embarrassed. He coughed and said, "I've been working on small-displacement four-cylinder turbocharged engines. EFI technology is an important part of it. I've used the current technological achievements in 150cc engines. The engine is installed, a single-cylinder engine, and an electronic nozzle is installed at the position of the carburetor. The electronic control unit is written by the electronic technicians of my team. The functions are relatively simple, but there is no problem in achieving reduced fuel consumption and more complete combustion.”

Yao Yuan was immediately happy, "You still have electronic technicians in your team."

"Yes, we basically have all the staff, but we are short of manpower." Yuri said.

This wasn't just a surprise, it was pie in the sky.

You must know that EFI technology is still a popular technology that many major manufacturers are stepping up to develop, and it is still in an immature and unstable state.

Chunfeng Academy of Sciences actually developed its own EFI technology, which is equivalent to standing on the same starting line as other major manufacturers.

I really didn't expect that Yuri's team dug back from the Czech Republic had such a treasure as an electronic technology researcher.

At the same time, it also reminded Yao Yuan that the research on electronic technology must start.

Yao Yuan said with emotion, "Electronic technology research is a bottomless pit, but I will fully support your research. In this way, let's list the automotive electronic technology separately. You are always in charge, and I will provide separate research funding."

The first sentence he said was electronic technology, and the second sentence was about electronic technology for vehicles. No one heard Yao Yuan's ambition.

The scope of electronic technology is too large...

In another 10 years, the annual R&D expenditure of 200 billion US dollars will only be enough for electronic technology R&D...

"Really?" Yuri was dumbfounded, this kind of surprise appeared too easily.

"Of course it's true." Yao Yuan waved his hand, "If you want to do it, do it big, do it well, do it in the direction of high-tech, or the same sentence, don't worry about funding."

Yuri was very excited, "Thank you, Mr. Yao!"

Yao Yuan took a closer look at the disassembled 150cc engine, and found that it was not much different from his guess. It was indeed a relatively simple electronic fuel injection device, and it could not achieve the precise control that would be achieved after 20 years. How much oxygen content to adjust.

However, even so, it is at least 10 years ahead of other domestic manufacturers!

However, even if it is as perfect as it is 20 years later, he does not intend to use this technology now.

He was satisfied with the results of the 150cc project, and then said seriously, "First of all, I am very satisfied with the work of your two teams. Your results have exceeded my expectations."

"I decided to list EFI technology as a follow-up and in-depth research catalog. The main direction is automobile engines, not motorcycle engines. However, there will be no plans to put engines using this technology into mass-produced models for at least five years."

Zhan Chenggui was the first to be anxious, "Why? Mr. Yao, using this technology will save fuel and provide more fuel. It can be said that this is our signature!"

It's hard to come up with a technology that can fill the gap in the country. Who doesn't want to put it into commercial use and let more people benefit from the new technology?

Chen Mingliang didn't understand either, but he didn't dare to object on the spot like Zhan Chenggui did.

Yuri didn't understand either, but he had a higher EQ, so he didn't object right away, but thought seriously—why did Yao Yuan hide this technology.

No, to be precise, it is not snow storage, but to continue to study in depth but not to put it into commercial use.

New technologies must be put into commercial use as soon as possible in exchange for money, and only with money can we continue to invest in research and development, so that a healthy closed loop can be formed, which is the long-term solution.

Yao Yuan is obviously not a short-sighted person, so there must be other reasons.

Most of the engines used by other domestic manufacturers now come from foreign technologies. The 150cc engine developed by Chunfeng Academy of Sciences is based on a variety of mass-produced engines with the same displacement abroad. It is a new thing with its own obvious technical characteristics, that is, a new of an engine.

This has already surpassed other manufacturers by a few blocks. Coupled with EFI technology, one can imagine how hot the sales will be in the future.

This is what everyone, including Zhan Chenggui, thinks.

At this time, He Xueli finished talking with Jitaro Sanme about the contract, and Jitaro Sanme hurried back to the hotel to make long-distance calls with the head office. He Xueli came over, and after knowing everyone's doubts, she fell into deep thought.

Obviously, she didn't understand either.

What Yao Yuan is best at is exchanging technology for funds. Isn't that the case with the cooperation with Mitsubishi Motors?

Why do you come up with new technologies yourself but don't launch them into the market?
