Rebirth of the 80s New Farmer

Chapter 2033 Unicom Number Assignment

Even if Mitsubishi's engine is not the most advanced in the world, it is still much higher than Nanwan Weiqi's existing technology.

Although Hengbida's engine is also a genuine Japanese product, after all, it is only a product of a small factory in Japan, and it is incomparable with Mitsubishi.

In the previous life, Wanfeng really didn't know much about car engines, because this thing can't be repaired anywhere like a truck. If there is a problem with a car, it will be taken to a 4S shop.

He has never worked in a 4S shop. Even if he is interested in machinery, where can he get in touch with the engine of a car?
Although there is not much research on car engines, he still has some understanding of Mitsubishi engines because they are everywhere.

The 4L engine of Mitsubishi 93G1.8 seems to have been used by Junjie and Hafei Saibao.

This engine should be launched in August next year, and someone wants to sell this technology now?
Besides, Mitsubishi is not an ordinary company in Japan. Strictly speaking, it is a military industrial enterprise. The confidentiality work of military industrial enterprises is the most stringent level. It is definitely not an ordinary person who can get information from Mitsubishi.

Although this is just a civilian car engine.

Why does it feel like a trap?
At that time, Wan Feng didn't ask Nobu Asada from what channel he could get the blueprints, and he directly approved the money for him to handle it.

Thinking about it now, I always feel that the decision was made too hastily.

Wan Feng happened to go to Shenzhen when Asada Shin returned to Japan to visit relatives. He came back in mid-May. After Wan Feng knew the news, Wan Feng gave him money on the spot to handle the matter.

After more than a month passed, Nobu Asada finally came back.

He really brought back an incomplete design drawing of Mitsubishi's new engine.

In the last life, this Mitsubishi engine claimed to be the world's first in-cylinder direct-injection gasoline engine with modern technology.

In-cylinder direct-injection engine is actually not a new technology. Mercedes-Benz did it in 300. At that time, the Mercedes-Benz [-]SL was equipped with the world's first in-cylinder direct-injection engine.

The 198L in-line six-cylinder engine code-named M3.0 is the mechanical gasoline direct injection system equipped on this Mercedes-Benz. The maximum output power of about 160kw is almost double that of gasoline engines with the same displacement that commonly used carburetors at that time!Fuel consumption has also been reduced by around 10%.

But there is one huge problem that cannot be solved.

Since the electronic control technology was not yet developed at that time, it was impossible to realize the way that the high-pressure fuel pump pressurizes the gasoline into the common rail, and then the solenoid valve or piezoelectric injector independently controls the fuel injection timing and fuel injection volume.The 198L in-line six-cylinder engine of this M3.0 uses a crankshaft-driven high-pressure oil pump to pressurize the fuel and then inject it into the cylinder. The direct disadvantage of this feature is the period from engine flameout to complete stop. Inside, the gasoline injected into the cylinder cannot be burned.

The unburned gasoline flows into the oil pan along the cylinder wall.

The engine oil in the oil sump will be diluted if it is mixed with gasoline.

This is a big problem. If the engine oil at the oil base cannot be changed in time, accidents such as chemical tile sticking to the cylinder will occur when the engine oil is diluted to the point where it loses its lubricating performance.

Therefore, at that time, the car had to change the oil at the bottom of the oil every [-] to [-] kilometers.

This problem is not big or small, and it was not solved until the end of the 80s. Although many European and American manufacturers made efforts in the middle, they all had little effect. From the 50s to the 80s, there was almost no progress in this technology.

Therefore, although the direct injection engine has been made for decades, its application range is not wide, and its impact is not very great.

Mitsubishi's 4G931.8L engine is a true in-cylinder direct injection engine that does not leak oil to the oil bottom.

To this end Mitsubishi also registered the GDI trademark.

Although Mitsubishi has solved the problem of no oil leakage, these GDI engines are not fully mature, and they have not seen the advantages of fuel saving and the shortcomings in emissions, so they have not received good market response.

Afterwards, the technology has been continuously improved before it is considered mature.

In [-] and [-], Nissan and Toyota released their own direct injection technology. It was not until [-] that Renault announced its own direct injection technology in Europe.

The blueprint that Nobu Asada brought back was not complete or perfect, but it was the real blueprint that Mitsubishi was developing.

Therefore, after being confirmed by all the people who research gasoline engines in the Nanwan Group, Wan Feng immediately formed an engine public relations team with more than 200 people. You can start developing this engine that Mitsubishi has not yet fully developed.

The main thing is to study the direct injection technology on this engine.

Wanfeng's goal is to strive to have its own direct injection technology within three years.

If Nanwan can master the direct injection technology, then in the next 30 to [-] years, Nanwan Weiqi will have the courage and confidence to compete with European, American and Japanese cars.

For this reason, Wan Feng's first allocation in advance was [-] million yuan.

This is not the time to save money, this technology is a big profit even if it can be won by spending one billion.

And Wan Feng also promised that if this technology is overcome within three years, he will award a bonus of tens of millions.

Since some of the people in the engine department have been transferred to public relations, the rest of the people can no longer be divided into each other, and the number of people divided is not enough.

As a result, people who looked at each other with deep hatred and hatred yesterday got together and called brothers and sisters together today.

From this, Wan Feng came to the conclusion that if you care about face skin, it is a value-preserving commodity such as gold, silver and jewelry. You don't care about it, and its value is not much different from shoe soles.

The engines developed by these people are almost done. Now everyone can get together and communicate.

Wan Feng made a hasty trip to Beijing after completing the research and development task of the engine.

July NO.17, China Unicom began to issue numbers.

The start of number allocation means that some GSM networks that have been laid since last year are ready for use, and Beijing, Shanghai, Guangzhou and Shenzhen will naturally become the first batch of beneficiaries.

Of course, Bohai Hongya also became the beneficiary area of ​​the first batch of telephones. Many people don't understand why Hongya, a small county-level city in Beiliao, became the first batch of GSM mobile phone accounts?

Wan Feng did not intend to explain this question.

The numbers in this period were not eleven digits, but ten digits.

Wan Feng ordered 130 numbers in the first batch. Although he didn't get seven numbers with the same number, he still got some numbers with [-] suffix with six numbers and ending with five numbers with the same number.

Furthermore, I also got a few progressive numbers like 1301234567.

These numbers were all requested by the bosses in Jiangwei Industrial Zone, and they knew that Wan Feng could get some better numbers.

Fortunately, there were still a small number of people who used mobile phones at that time, otherwise these good numbers would not be so easy to get.
