Chapter 365: Vulcan Diesel Engine

For export, only diesel engines are used.
The diesel engine equipped with Vulcan series excavators has average performance.
The power is 350KW. About 475 horsepower. It is claimed to be 500 horsepower. Obviously, there is a certain amount of moisture.
However, this is also a practice in the construction machinery industry. It must be pompous.
Compared with the products of other companies, Vulcan diesel engines have no advantage.
Both power and fuel consumption are at a medium level.
However, it is already the best diesel engine Qin Xueqing can find.
If you want to introduce more advanced diesel engines, the cost will increase substantially. The final calculation is impossible. Unless it is Wang Buyan.
That's right, it was Wang Buyan again.
Qin Xueqing has determined that Wang Bu'an can solve this problem.
He can even make an engine as abnormal as the Rock 150. It shouldn't be difficult to improve the diesel engine.
What high-pressure common rail system, in Wang Bu'an's eyes, is scum.
"I'll help you beat the back." Miss Qin took the initiative to show her affection.
"I found that I have only 50% of the equity is definitely a big loss." Wang Bu'an muttered.
"All for you, all for you. I'll help you work." Miss Qin quickly said, "I only need 10,000 yuan a month. It's enough to eat. I definitely don't need one more point."
"Huh." Wang Bu'an knew that the other party was advancing with retreat. Cunning woman. However, he didn't care too much.
Making money is only an incidental purpose. He can't spend his money now.
As the saying goes, the money that is not spent is not yours.
He has no time to spend money now!
It's better to be a good person than to deposit money in the bank to get moldy.
Give Miss Qin some flowers generously.
Maybe when I can provoke Miss Qin's combat effectiveness.
As long as Qin Xueqing is willing to work hard, it is not impossible for Qin Xue Group to become the world's top industrial group.
Speaking a little bit harshly, with his own support, a pig can fly.
Besides, Qin Xueqing is definitely not a pig. She is very smart.
Just use her ambition in her career.
"You're good at beating the back," Wang Bu said angrily.
"Of course. I learned it specifically. Otherwise, let's seduce you?" Qin Xueqing said very straightforwardly.
"What's the use of seduce me?"
"Of course it works. PlayerUnknown's Battlegrounds. Resurrected."
"What if I don't help you?"
"Then I have to ask Huang Ruoxi. She will definitely help me."
"You guys..."
Wang Bu'an didn't know what to say.
Huang Ruoxi is enthusiastic. Sense of justice is overwhelming. Helpful. It is simply the best in the world.
As long as she can help, she will definitely help.
These women all discovered Huang Ruoxi's point. All went to her.
As long as Huang Ruoxi spoke, he would definitely not refuse.
How could he reject Huang Ruoxi?
Just don't know, how many people Huang Ruoxi is going to accept?
Does she know the word?
It is estimated that she would not know.
There are only legal provisions in her mind.
Even falling in love is a waste of time.
What kind of romance, what is going on, what is going on, attorney Huang doesn't care at all.
If you have time to have a candlelight dinner, it is better to recite a few legal provisions.
Unless he drags and pulls, he will go.
Speaking of Cao Cao, Cao Cao arrived.
Huang Ruoxi's phone call suddenly came.
"Lawyer Huang." Wang Buyan deliberately prolonged his tone.
"What are you doing?" Huang Ruoxi asked.
"Qin Xueqing is seduce me. Give me a back beat. Would you like to video it."
"No. She does things, I don't worry."
"what?"
Wang Bu was stunned.
Lawyer Huang is so direct and decisive.
It doesn't mean to check the Gang at all. On the contrary, there seems to be a bit of encouragement?
"The gold master behind the walrus battery, I have found out."
"who is it?"
"Luo Shen."
"she was?"
Wang Bu'an immediately showed the shadow of Luoshen.
The legendary eunuch.
The man who forced himself out of the palace.
He changed himself from a man to a woman abruptly.
The rumors from the outside world can be said to be rumors, and no one knows whether it is true or false.
Last time I met, I felt that Luoshen should be a natural beauty. However, afterwards, I heard a lot of rumors and talk outside, and I felt that she might really have had a operation.
In her body, there is always a strange, coquettish smell. It's different from ordinary women.
Especially when she stared at Huang Ruoxi's eyes. Definitely not a woman.
It feels like she wants to take Huang Ruoxi away anytime.
"Is Luoshen a man or a woman?" Wang Bu'an asked dullly.
"Female. Born to be a girl." Huang Ruoxi replied affirmatively.
"Are you sure?"
"I asked lawyer Gu to investigate in detail."
"Oh."
Wang Bu'an was relieved.
Gu Xialiu didn't have any other skills, but he was very good at listening to the corner. There are a lot of masters and strangers around him.
He said that Luoshen is female, and that Luoshen must be female.
As long as Luoshen is not a male. Otherwise, Wang Bu'an will definitely be jealous.
Dare to stare at Huang Ruoxi with such eyes. Obviously, she wanted to rob Wang Bu'an's woman. Is it tolerable or unbearable? Destroy his nine clans first.
"There must be someone behind Luoshen," Wang Bu'an said.
"We can't investigate temporarily." Huang Ruoxi said.
"Let's take a look first."
"it is good."
"Right. I'll take the exam a few days. Will you come to cheer me up?"
"Come!"
Wang Bu'an answered without thinking.
nonsense!
Can he not come?
This exam is related to the future career of Lawyer Huang, how can he not take it seriously?
After the exam, Huang Ruoxi is a real trainee lawyer.
I haven't taken the exam, and I have to wait another year.
After the examination, the grass-roots team of Lawyer Huang can be officially released.
I haven't taken the exam, and I have to wait another year.
After the exam, Lawyer Huang will be able to go to court in person with grandeur.
If you haven't taken the exam, you have to ask someone to do it in court.
"Goodbye."
"Goodbye."
Continue to study diesel engines.
Suddenly I found myself full of power.
If you don’t come up with something decent, I’m really sorry to the motherland and the people...
"This is Master Lin."
"This is Master Liu."
Qin Xueqing called in the designer of the diesel engine.
Said it is a design, it is actually an improvement made on the basis of other diesel engines.
This kind of improvement can also be called a copycat.
For the time being, Qin Xue Group’s research and development capabilities can only do so.
It can be seen that without Wang Buyan's help, she would definitely be unable to do so.
How much can you improve on the diesel engine you copied?
A 5% improvement is already very powerful.
Even if it is a bad copy, the performance may go backwards. The gain is not worth the loss.
What I didn't say was the modification of the diesel engine.
Disassemble all the diesel engines.
Careful inspection of one part by one.
The robot wizard took the opportunity to make a detailed record of each part, looking for better quality substitutes.
The first is the nozzle.
It must be further strengthened.
The original nozzle has an accuracy of only 0.1 mm. To be increased to 0.01 mm.
The pressure also needs to increase. In order to achieve more precise injection.
A small nozzle embodies powerful technology.
Every diesel molecule must be burned up and not wasted.
In the process of oil transportation, there is always part of the oil running and not wanting to run. Want to be lazy. Pressure must be applied. Force them into the cylinder.
When the pressure is high, the jet will naturally become stronger. Contact with oxygen is sufficient.
However, the higher the precision of the nozzle, the easier it is to clog.
This again involves the oil filter.
The oil filter must also be improved.
All impurities other than diesel must be filtered out.
Otherwise, once the nozzle is blocked, it is still more troublesome to replace it. Need to disassemble.
The oil filter is so improved?
Of course, high-tech raw materials are used.
Among them, the carbon fiber diaphragm is very good. It can filter impurities very well.
The only disadvantage is that the cost is a bit high.
However, for Wang Bu'an, this cost is acceptable.
He produced the carbon fiber himself. How much can it cost? It must be less than half of the market price. It is calculated at most 40%.
What didn't say, immediately adopted carbon fiber as the main raw material of the oil filter.
Turbocharging is also necessary.
The fundamental purpose of turbocharging is to increase oxygen.
Simply relying on the turbofan to absorb air in, still contains too much nitrogen, which affects the combustion effect.
How to do?
Isolate nitrogen.
Adsorb nitrogen.
Use special materials to absorb part of the nitrogen atoms.
Use chemical reactions to consume part of the nitrogen atoms. The rest is naturally oxygen. With the same volume, the higher the oxygen content, the higher the combustion value.
The purity of oxygen is high~EbookFREE.me~ The injection of diesel is also fierce, and the temperature in the cylinder will rise sharply.
If the cylinder is not strong enough, the cylinder will burst.
Even if the cylinder does not burst, it will vibrate due to the high temperature. Eventually damage the cylinder.
Once the cylinder body is damaged, it is commonly known as pulling the cylinder. That is also the cylinder is scrapped. Either replace the cylinder. Either replace the entire engine.
How to do?
How to do?
Of course, the material of the cylinder was changed.
Cast iron is definitely not acceptable. Nichrome is also behind. Must be grade 4 high temperature wear-resistant alloy.
What kind of cylinder can achieve a high temperature of 15,000 degrees?
safe to use. It will never burst.
In addition, there are improvements in sealing and heat insulation.
The combustion efficiency of general diesel engines is about 50%. It means that half of the heat is gone.
If you want to improve the combustion efficiency, it must be sealed and insulated. Various rubber seals and various ceramic insulation layers need to be mixed and used to reduce the loss of every minute of heat.
After hundreds of large and small transformations, the new Vulcan diesel engine has finally come out.
The power is increased by about 35%, and the power exceeds 640 horsepower.
Fuel consumption has dropped by about 30%.
In this way, in terms of exports, it can occupy a certain advantage.
In addition, its manufacturing cost is also slightly reduced. On the whole, it is much better than the previous Vulcan diesel engine.
Wang Bu'an is most comforted that these diesel engines finally do not need to be produced in industrial parks.
It can be produced in the diesel engine division under the control of Qin Yuqing.
In other words, its output can be rapidly expanded. Not restricted by industrial parks.
what does this mean?
This means that diesel engines can be sold separately!
