Rebirth of the Auto Giant

To apply for a patent, you need to have finished products, and the precision requirements for manufacturing finished products of high-pressure common rail systems are very high, and currently domestic lathes cannot achieve it.

What to do?

Should we ask Lao Cao to import lathes through special channels?

No, now is not the time to put the high-pressure period common rail system into practice. The system camshaft mechanical high-pressure oil pump diesel system will last at least another twenty or thirty years.

Besides, this common rail system is very demanding. It has very high requirements on the quality of diesel and the filtration accuracy of diesel filters. The quality of diesel nowadays is so poor and the accuracy of electronically controlled injectors is so high. If the quality of diesel is not as good as that of diesel

If the filter element fails to meet the requirements, it can easily cause the electronically controlled fuel injector to be damaged and stuck, and the cost of the electronically controlled fuel injector is very expensive.

This is currently not in line with the national conditions in the country.

The price is so high and it might break easily, so who would dare to use it.

Now our requirements are not high, as long as it can be used, as for noise and emissions, we can just put them aside.

I just want to make a finished product and apply for a patent. There is no need to buy an imported lathe, and besides, it may not be available.

There is another difficulty, which is how to operate the "brain" electronic controller unit of the common rail system, also called a computer.

There are also sensors such as pressure sensors, fluid flow buffers (flow limiters) and pressure limiters. The most important thing is that electronically controlled injectors are the most difficult to manufacture.

The electronically controlled injector is the most critical and complex component in the common rail fuel system. Its function is to inject the fuel in the high-pressure fuel rail at the optimal level by controlling the opening and closing of the solenoid valve according to the control signal sent by the ECU.

Fuel injection timing, fuel injection quantity and fuel injection rate are injected into the combustion chamber of the diesel engine.

"It's difficult." Wang Shi sighed.

The car was driving slowly on the street. It was the peak flow of people after get off work. When the employees saw it was "Beijing a6666", they knew it belonged to their boss and automatically moved out of the way.

In 1987, bicycles were still the most common means of transportation.

At this time, Wang Shi's big brother rang, and Wang Shi picked up habitually, "Who is it?"

"Hello Mr. Wang, I am Huang Shan, director of the 640 Institute." The excited voice of a middle-aged man came from the other side of the phone.

Institute 640 is a large passenger aircraft design institute (namely 640 Institute) established in Shanghai based on more than 600 designers from the Third Aircraft Department, the Aviation Research Institute, and the Air Force.

"Hello Comrade Huang Shan, I'm very happy to hear your call. From the tone, it seems like something good is coming?" When Wang Shi heard the other party was so excited, could there be something good coming from Luck 10?

As the fund provider of Yun 10, it is normal for the other party to tell me any good things.

In 1984, the Yun-10 team applied for R&D funding of 30 million yuan from the state but was rejected. Later, it was stranded due to insufficient funds. If it weren't for itself, the Yun-10 team would have been disbanded just like history.

It was he who provided 200 million yuan of funding all at once. With sufficient funding, the current research and development of Yun-10 has been carried out smoothly.

"Mr. Wang, our Y-10 has just made its eighth flight to Lhasa, Tibet. So far, it has flown a total of 129 sorties/187 hours, with a maximum range of 3,600 kilometers, a maximum speed of 930 kilometers/hour, and a maximum take-off weight of 110

tons, with a maximum flight of 11,000 meters and a maximum air time of 5 hours and 49 minutes. Various flight tests have proven that the Y-10 aircraft has good performance." Huang Shan said excitedly.

"That's a good thing. Congratulations. How is the turbofan 8 engine?" Wang Shi said.

"So far, it's pretty good."

"Aviation engines are very important to aircraft, and their reliability is related to the lives of dozens or hundreds of people on the aircraft. What do you think of producing one or two for life-limiting experiments?" Wang Shi asked in a questioning tone.

"We have thought about this, but Mr. Wang, you also know how much it will cost to do this. The gas money alone is a bottomless pit, which is not appropriate."

If you really want to do a limit test, how much oil will you have to burn? Even if you have money, you can't burn it like this.

"Well, I'm overthinking it. Take your time. You won't get fat after one bite. We started late. As long as we don't give up, we will succeed one day." Wang Shi said.

"Yes, no matter what you do, the most important thing is persistence, persistence to achieve miracles, persistence to realize dreams." Huang Shan sighed.

"By the way, Director Huang, I have a few parts that cannot be manufactured outside due to very high precision requirements. I wonder if your 640 Institute can help me with them?" How could I forget about the big Buddha 640?

"No problem. Without Mr. Wang, our Yun-10 R&D team would have to be disbanded. Mr. Wang is our great benefactor of the Yun-10. How can we not be busy with such a busy schedule? Mr. Wang only prepares the drawings and leaves the rest to us."

Huang Shan said arrogantly.

"Okay, I will go there in person when the time comes. Due to the confidentiality of the product, I hope that Director Huang will not let a third party know about this." They are all sensible people. How could Huang Shan listen if he can become the director?

I can't understand what Wang Shi meant.

This product must be a core secret for Tang Dynasty Power Company.

"Okay, we welcome Mr. Wang to come and inspect."

"I don't want to take the inspection seriously. Let's go and see the lucky 10 in my heart. Then I can take some photos as a souvenir."

Wang Shi said and hung up the phone.

He breathed a sigh of relief.

Now the manufacturing aspect is sorted out.

As the 640th Institute that manufactures aircraft, it has gathered skilled craftsmen drawn from all over the country. The equipment inside is also the most advanced in the country. It manufactures diesel common rail parts and develops sensors. Wang Shi plans to see if he can use these sensors.

Let the other party do it.

Of course, there will definitely be difficulties, but we can work together to overcome them.

Regarding the issue of accuracy, we are almost there. The most important thing is to make the finished product first and apply for a patent, and then improve the accuracy slowly. Although Wang Shi also has his own R&D team, these advanced things have not yet applied for a patent, the less

The better people know.

Who knows if there are commercial spies around him.

At the end of May, Wang Shi completed the production drawings of several high-pressure fuel common rail system high-pressure oil pumps, high-pressure oil rails (common rail pipes), electronically controlled injectors (without solenoid valves), and high-pressure oil pipes.

Wang Shi arranged the affairs of the unit, then took two bodyguards, Zhang Long and Zhao Hu, and boarded the plane to the Magic City with a salute.

Both bodyguards have gun licenses and will be released after checking in at the airport.

The passenger aircraft is an Il-14 with 24 seats.

The IL-14 aircraft is a piston twin-engine transport aircraft designed and improved by the Soviet Ilyushin Design Bureau on the basis of the IL-12 transport aircraft. It flew on July 15, 1950, and was put into use on Soviet civil aviation routes at the end of 1954.

China imported 55 IL-14 passenger aircraft from 1956 to 1960, including three seating arrangements: 18 seats, 24 seats, and 32 seats.

There are very few people who can afford to fly at this time. They are usually civil servants on business trips from their workplaces, and there are not many guests on the plane.

The stewardess is very beautiful. She wears a long skirt tied around her waist like a willow breeze. She has short permed hair and healthy skin. She looks very energetic. She looks really beautiful and original. However, there is only one stewardess in the entire plane.

"Comrade, what would you like to drink?" the stewardess asked Wang Shi.

"What's there?" This is Wang Shi's first time flying in this era, and he doesn't know what kind of drinks are on the plane now.

"There are soda biscuits and Maotai liquor..."

"Ahem..." When Wang Shi heard that there was still Maotai, he choked and coughed, almost losing his breath.

Grandma, in the past decades, not to mention wine, even buffalo milk was not allowed on the plane, but now Maotai is provided, which is really shocking.

Are people becoming more timid?
