Chapter 687 Honda can't sit still
Seeing if it was Sergei Izotov who had a few whispered conversations with his assistants, and even used Russian in the middle of the conversation, the executives of Huateng Industrial Group were anxious, but they were The atmosphere did not dare to take a breath.

Yes, this will allow the Huateng Industrial Group's engine development team headed by Sergey Izotov to conduct a feasibility assessment of Zhang Qihang's V8 engine.

Although Zhang Qihang took out the design materials, the current Huateng Industrial Group is transforming into a formalized one. Naturally, it is impossible to decide on such a large project by relying on Zhang Qihang's words, even if everyone thinks it is not necessary, but Zhang Qihang still resisted all opinions and let the engine development team headed by Sergei Izotov give a judgment on this V8 engine plan: from a technical point of view, can this engine be manufactured? ?

Although Sergei Izotov is an expert in military jet engines, he joined the project of imitating the "Wright" R-29 piston radial engine on the B-3350 bomber of the United States in the early years. The industrial group later developed China's first heavy-oil piston aircraft engine fueled by aviation kerosene. It can be said that he has learned across the two fields of piston engines and turbine engines. Although he has been engaged in research on military engine technology , development, but as an evaluation expert, it is perfect.

Fortunately, we didn't make everyone wait too long. After a while, Sergei Izotov's team ended the discussion. Under the eyes of everyone expecting, Sergei Izotov nodded affirmatively: "Gentlemen, Although some places still need further calculations to be sure, I can assure you on my honor that Mr. Zhang's design is feasible from a technical point of view, and it also has the ability to realize engineering..."

"call……"

As soon as Sergei Izotov's words fell, everyone at the scene breathed a sigh of relief: the plan is feasible, and that would be great.

Sergey Izotov went on to say: "In addition, on this engine, the intake and exhaust continuously variable valve system designed by Mr. Zhang is really interesting. If this system can really be made , can greatly improve the intake and exhaust efficiency of the engine and reduce fuel consumption, this thing has given me a lot of inspiration, maybe we can transplant this system to our heavy fuel oil engine."

Speaking of this, Sergei Izotov looked at Zhang Qihang with amazement in his eyes.

Yes, it’s amazing. When I saw this set of continuously variable valve system for intake and exhaust, I never thought that this method can be used to adjust the intake and exhaust system of the engine in real time. Sergey Izzo Tove, I feel that I have really opened my eyes: Is it possible to play like this on a piston engine? !

"It's nothing, this technology has been around for a long time," Zhang Qihang waved his hand modestly, he is not willing to take credit for this kind of thing: "For example, Honda's VTEC technology, Toyota's VVT technology and Mitsubishi's MIVEC technology, etc., we These things are all the same train of thought.”

Sergey Izotov was a little surprised: "Is that so?"

"Yes," Zhang Qihang nodded affirmatively: "Actually, in terms of the advanced level of technological development, civilian engines are ahead of military engines in many aspects, such as fuel consumption, reliability, durability, etc. Higher than military engines, and military engines are stronger than explosive power, and some even require that they can continue to work for a period of time after being hit by a bullet..."

"That's right."

Sergei Izotov nodded repeatedly as he spoke, his face was still thoughtful, obviously he had already started to consider transplanting this intake and exhaust continuously variable valve system to the 6-cylinder heavy fuel aero engine he is currently developing , allowing this engine to achieve higher intake and exhaust efficiency while having lower fuel consumption.

Looking at Sergey Izotov's thoughtful look, Zhang Qihang was very satisfied. He nodded and said, "I think there are actually many places where the two can learn from each other. For example, although military engines do not particularly pursue low Fuel consumption, but the fuel consumption is reduced. Under the condition of carrying the same amount of fuel, it is equivalent to increasing the driving distance of the vehicle in disguise, which is equivalent to increasing the combat effectiveness.

Another example is the heavy fuel oil engine developed by our company. In the final analysis, this engine can be regarded as a civil aviation engine. It would be a good thing if the fuel consumption can be reduced a little. "

Sergey Izotov nodded again and again, agreeing to Zhang Qihang's words.

While Zhang Qihang was chatting happily with Sergey Izotov, the management of the group headed by Jiang He and Feng Guoqing was also discussing enthusiastically.

After Sergei Izotov confirmed that the V8 engine designed by Mr. Zhang is indeed feasible, and the rest is just a matter of engineering realization, their doubts completely disappeared. At this moment, they only have One thought: V8 engine!This is China's first V8 engine that can be mass-produced in the true sense!
Although the FAW Group was able to produce V30 engines as early as 8 or [-] years ago, they are not called industrialized mass production at all. If we want to talk about industrialized mass production, we still have to look at our Huateng Industrial Group!
China's first industrialized mass-produced V8 engine, what an honor is this? !
For a while, none of the people could calm down and expressed their opinions one after another, even those new managers recommended by the city to join in before...

"When our country was developing the Red Flag, it took a lot of effort to cast a qualified V8 engine body. It is said that FAW cast 100 mid-cylinders at one time, but only 2 were qualified, and the others were all It's a waste product," Yang Zhijun said loudly: "This fully demonstrates how difficult the manufacturing process of this large-displacement V8 engine is.

But this is not to blame for FAW. After all, how long ago was the founding of our country in the 50s? There were not many talents and technologies for such large-scale castings. But it is different now. After so many years of development, Our country has also cultivated a lot of talents in casting. For example, the WD615 diesel engine produced by Weichai is much larger than the V770 gasoline engine of Hongqi CA8. We can invite some teachers from Weichai to come with us Get the key cylinder casting, as long as the cylinder casting is done, everything else is trivial. "

But as soon as the words were uttered, they immediately attracted doubts: "This is also a way, but the engine of Weichai Company is made of ductile iron, and the engine designed by Mr. Zhang is all aluminum. I don't doubt that Weichai's Comrades have the ability to cast large engine cylinders, but ductile iron and cast aluminum are two different things, right?"

As soon as this question was raised, many people also expressed their agreement...

"Makes sense."

"That's true. The physical properties of ductile iron and aluminum are completely different."

"Who said it wasn't? I even suspect that Weichai doesn't understand cast aluminum at all, let alone Mr. Zhang also gave suggestions, suggesting the use of low-pressure cast aluminum technology. It is estimated that Weichai's technology and experience in this area can directly to zero."

"Yes! The ordinary casting process is to heat and melt steel or iron, pour it into a pre-made mold, and then wait for the casting to cool slowly. The process and manufacturing process sound simple, but in fact it is very technical. High, such as how to ensure that there will be no air bubbles in the casting? For example, slight differences in pouring time, speed, angle, and even molten iron temperature may lead to great differences in the quality consistency of the final product..."

…………

Everyone talked a lot, and soon the building was distorted, and the building was distorted to the difference between cast aluminum and cast iron, ordinary casting and pressure casting.

While everyone was talking about it, Zhang Qihang was also talking about it with Sergey Izotov.Sergei Izotov frowned and said to Zhang Qihang: "Zhang, I don't understand why you use the low-pressure casting process? The engine cylinder is not something that requires particularly high strength, and conventional casting can meet the performance requirements." I asked for it."

This is what Sergey Izotov doesn't understand very much. In his opinion, the first technical route of this engine is traditional gray cast iron. Of course, it is also good to use ductile iron. Not only is the price cheap, but the quality is also guaranteed. But now, instead of choosing gray cast iron and ductile iron, Zhang Qihang chose the most difficult low-pressure cast aluminum. This really made Sergei Izotov wonder what Zhang Qihang was thinking.

"Old Xie, I understand what you mean," Zhang Qihang nodded repeatedly: "If it is just to produce a V8 engine that can be mass-produced, as you said, ordinary ductile iron is enough. The reason why I decided to The core cylinder block of this engine is produced by the low-pressure aluminum casting process, because I hope that through this project, the entire group can achieve a technological leap and leap forward. With this project, we must not only have the ability to manufacture V8 engines , but also to understand all the technologies in it!"

Counting this, Zhang Qihang couldn't help getting a little excited: "Thank you for thinking about it, many companies in our country...or maybe all of them, are still in the 'compared with the gourd painting' in terms of engine design and manufacturing. , The foreign party gave us a set of drawings and taught us how to produce this engine, and our company can only produce this engine according to the given process, completely knowing what it is and not knowing why.

What I want is to let our group's engine research and development team grow up as soon as possible through this project, and thoroughly understand this V8 engine. As long as they understand this engine thoroughly, we will be more flexible in terms of engines in the future:
Want an inline-four engine?Simple, split this V8 from the middle to get a straight four;
Want a V6 engine?It's also simple, cut off two cylinders from the V8 to get the V6;

V8都不能满足我们的产品定位，需要V10甚至是V12？那就再旁边再接上2个或者4个汽缸嘛。

For the same straight 4 or V6, by fine-tuning the piston stroke or cylinder bore, engines with different displacements can be derived under the same configuration; and through the control of intake and exhaust, different displacements can be adjusted under the same displacement. The power to meet different market needs and positioning..."

Speaking of this, Zhang Qihang said to Sergei Izotov with a face of reverie: "If our company's engine research and development department can do what I said, it will be like building blocks on the basis of this V8 engine." To calmly build the engine that the company needs, Lao Xie, I will be satisfied on this day."

Sergey Izotov was dumbfounded, he didn't expect Zhang Qihang's ambition to be so big!

When people like himself were still thinking about completing this project smoothly, Zhang Qihang had already considered this project as the "Frunze Military Academy". On the second floor, and I'm already standing on the fifth floor"?
But the shock is the shock. If it is from the perspective of cultivating talents, then there is no problem. No matter how difficult the project is, it is worth it!
Thinking of this, Sergei Izotov nodded immediately: "Then I have no objection... Well, I will also bring my team to participate in making a V8 heavy oil engine based on this V8 engine come out."

In the field of civil aviation, four-cylinder and six-cylinder piston internal combustion engines are the most widely used, but there is also a certain market demand for eight-cylinder piston aircraft engines. It can even be said that eight-cylinder engines firmly occupy the piston aviation industry. For the "high-end" positioning of the engine, for the aviation department of Huateng Industrial Group, the demand for the eight-cylinder engine is actually not high when it has developed a 4-cylinder heavy-oil aviation engine and is developing a six-cylinder heavy-oil piston engine. So urgent, but if the company itself is going to develop a V8 engine, the situation will be completely different. The aviation department will also participate, which will not only help to share the R&D cost of the engine, but also reduce the R&D cost on its own side, such as If the low-pressure cast aluminum process is used, the overall weight of the engine can be reduced to the greatest extent. After the successful development of this process, it can even be used on the current two engines.

Zhang Qihang naturally knew this, so he naturally would not object: "Of course it's no problem."

Sergey Izotov couldn't help but smile.After saying this, he couldn't help asking curiously: "But how can you let Honda know about this matter without any trace?"

Sergei Izotov actually knew that Zhang Qihang was planning to use this project to put pressure on Honda. He was not surprised that Zhang Qihang had such an idea, but he also knew that the key to this matter was how to Unobtrusively convinced Honda that this was not a conspiracy by Huateng Industrial Group against itself.

"Ha ha……"

Zhang Qihang smiled, and said with a smile: "Old Xie, you must know that our country has many enthusiastic people."
