But at this moment, Senior Brother Wei was a little confused: "The settling fee is a full 70, plus this year's salary, bonus, and project bonus, no matter what, it is enough to sell a small apartment with two bedrooms and one living room. Well, how could it not be enough?"

"A small apartment?"

"Yes, even if he is married, he will only live with two people. In the early stage, a small apartment for two people must be enough."

"Yihang, are you not married yet?" Wang Feng is still very confident in his memory: "Generally speaking, according to your age, if you are not married yet, then generally speaking, you can leave your home according to your requirements. There will definitely be more.”

"So if you want to buy it, it is definitely recommended that you buy a large-sized apartment. Although it is cheaper for a small-sized apartment, it will definitely be troublesome in the later stage. And if you want to change it at that time, this one is not very easy to sell."

"That, Professor, I will consider it." Liu Yihang scratched his head and then replied.

"But this is just my personal suggestion. The specifics still depend on you. But if you want to buy a large apartment, you can wait a little. Our family buildings have already started construction, and they are basically all You will definitely have one of the large apartments ranging from 120 square meters to 150 square meters."

"So if you want to buy now, you'd better look for one that is easier to sell, has circulation capacity or is easier to rent out. Of course, if you plan to live in the other set, then there are not so many requirements gone."

Wang Feng had stayed here longer than they did, so he was quite familiar with the situation.His family had also invested in a lot of real estate in Jincheng, and had some understanding of the second-hand housing market.It is not easy to sell second-hand houses in most places, unless you are within the second ring road.

But according to their economic level, it is impossible to afford a house in the second ring road.Then there are more things to consider.

This is basically the end of the discussion about welfare. The family members basically only got to know the bottom line with these small high-level executives. The circulation rate is still relatively high, so it is not suitable to release the news for the time being.

At noon, the three of them ate a light meal in the cafeteria. In fact, the cafeteria of the unit is not too different from the buffet in the hotel.It's just that the ingredients are fresher and the taste is better.

Of course, there must be no alcohol. After all, researchers generally try to drink as little as possible, especially young researchers. Alcohol is still relatively harmful to the brain.

Of course, after the age of 45, there are not so many things to pay attention to. After all, the human brain has basically begun to decline at that time, and at that time, human energy cannot support too much energy-consuming research. At that time, you can relax a little a little.

After eating a light meal and taking a nap, Wang Feng's phone rang.

"Hi, may I ask who is it?"

"I'm Lao Zhou. You forget me so quickly, but it makes me so sad."

"This... Isn't this usually busy at work?"

"Just kidding, understandable, understandable."

"Professor Wang, you should be in the laboratory this afternoon, right?"

"What's matter?"

"Wait for me there a moment, we'll be there in a minute."

"Hello!"

"Hello there!"

Not only Manager Zhou came, but also the boss of FAW.In fact, FAW is not just selling cars, he is also responsible for the research and development of our domestic engines, but the effect is really hard to describe.

Of course, this is definitely not to blame anyone, after all, they have been cultivating in this field for so long.I don't know how much money has been invested back and forth. It is really too difficult for us to catch up with others in this field.

Of course, difficulty does not mean that we will not catch up.It's just that what we need may be more overtaking from the side.Instead of racing with others on the straight.

Can we create a world-advanced engine?
The answer is definitely yes. According to our current industrial capabilities, we can definitely build such an engine, and we don't even need to think about it.

But there is a very big problem, that is the problem of cost.

It is now 2022. In the past 22 years, China's new energy vehicles and industrial chain have made great strides. Not only have leading innovative new energy autonomous vehicle products, but also world-class battery/motor suppliers have emerged...

But at the same time, the engine is still the core of the automobile industry.

It is the core component of the largest civilian industrial product. Its performance directly determines the performance and value of the vehicle. It is a complex system that highly integrates advanced thermal/mechanical/electrical technologies. Its operation is thousands of components. The precise coordination of these thousands of parts must be able to quickly and accurately output power when moving together, reduce fuel consumption as much as possible and strictly control pollutant emissions.

Such a heart represents not only a machine, but also a huge capability of the automobile industry.Therefore, the "big question" of "whether China can manufacture automobile engines of the world's mainstream level" is not only a technical issue, but also an issue of industrial development.

In the past half century, China's engine manufacturing has always faced a difficult competitive situation: First, there are many difficulties in engine technology itself; second, engine technology needs continuous investment to meet the requirements of the market and regulations.

It is not enough to solve difficult problems and create them. The requirements of the market and regulations on engine performance are constantly changing. Each generation of engines requires optimization and improvement from the level of various parts to the system level. This is a test of the capabilities of OEMs. Third, automotive engines The technology is for civilian use, and cost control is very critical.

Building an automobile engine is different from building rockets. It always faces the test of mass production and commercialization. On the basis of "manufacturing", it is also necessary to grasp the cost of mass production, and it is necessary to make double efforts in parts and manufacturing processes. Efforts should be made to grasp the cost of mass production. Finally, the competition in the vehicle market, which is 1:1 closely related to the engine, is severe.

Globally, more than 80% of passenger car engines are produced in-house by passenger car brands, which means that terminal vehicle sales are closely related to the scale of engine shipments.

The structure of the automobile industry has been stable for 100 years before the new energy revolution.

However, self-owned brands are fighting globalization in the domestic market, and there is an order of magnitude gap with competitors in terms of vehicle output. Naturally, it is difficult to achieve the same level of scale effect in engine shipments. Faced with difficulties, China's engine technology development has gone through difficulties. , once built a "world mainstream" engine from scratch.

64 years ago, as the only OEM in China, FAW built the first car engine and the first car in China. The following is quoted from the dictation of Li Gang, one of the pioneers of China's auto industry and senior student of the Automotive Department of Tsinghua University:

In order to solve a large number of technical problems of the engine, the general factory ordered me to organize five commando teams, which worked for more than a year...

Not to mention the process of tackling key problems, it is quite arduous.

I think that was the most glorious time in my life... In the early stage of the research, the task was tight, and I didn't close my eyes for up to 96 hours in a row, working day and night... Soviet experts also came to work as the chief designer of the Giss engine Invited to help us tackle the problem.

In the end, he failed to help, but brought back all our materials...

At that time, only the Soviet Union and the United States were engaged in V-type engines in the world, and other countries, including Japan and Germany, did not.And we built the V8 engine on our own.

Such a V8 car engine with a strong color of the times, relying on the top domestic talent team and making breakthroughs at all costs, finally "created" the world's mainstream models.

However, such research lacks sustainability. In the absence of a market, FAW Cars in the planned economy era lacked the ability to continuously invest in research and development.

Over a 1958-year period from 1984-25, there were few more improvements to this engine.

At the same time, the global automobile market has been changing with each passing day - the rise of the Japanese automobile industry has led to the introduction of Japanese economical cars into the world.In 1984, China's car imports reached their peak, and the Toyota Crown became the most common high-end car, while self-owned brand cars were even more bleak.

Like the semiconductor industry, that's a lost 25 years.

In the lost 25 years, even if we have money, people, enough energy and time to do these things, and enough technology accumulation to break the blockade, the lost 25 years are forever I can't get it back either.

The main shackles of domestic engines are the shackles of cost. The most difficult thing to maintain is low-cost long-term stable operation and the biggest bottleneck of brand influence. These three points are also the Achilles of almost all domestic high-end industrial products. His heel.

Frankly speaking, industrial products, as long as the price is high enough, can meet the requirements you can think of, whether it is processing accuracy, mechanical properties, durability, etc., all problems are cost issues (this is especially true for civilian industrial products, There is still a research and development process for military technology, and the proportion of civilian technology research and development is not high). In short, the problem is not that the requirements cannot be met, but that the cost of foreign products or lower than the cost of foreign products is used to achieve product quality similar to foreign products that have been running stably for a long time .

For example, in a certain project, there is a content of nickel-silicon carbide ceramic coating on the aluminum alloy body. This technology has just started in China, and only a few military laboratories and scientific research units have it. Commercialization The level is very low (2016). There is a mature supply chain system in the United States. Our engine needs to be matured by domestic supporting manufacturers before the engine performance can be stable. It is no problem to make a batch of experimental ones, and it is also very good. use, but the price is...

And on the engine, similar details are everywhere, for example, sealed graphite-metal gaskets, fastening glue, carburetor diaphragms, bearing performance, etc., everything can go wrong, it can be Something went wrong.

You can only buy cheap, easy-to-use and durable products naturally when the entire industrial supply system is at a high level. At that time, there will be an engine that everyone likes and recognizes. It will make a good impression of the domestic engine.

When Karl Benz invented the diesel engine, the West has been developing the internal combustion engine for more than 200 years, and it took us 60 years (even the development of civilian technology is nearly 30 years) to catch up to where we are today. Searching up and down, I hope that domestic engines can go further, and I hope that electric vehicles can overtake on curves.

The good news is that they have now achieved such a goal, but the bad news is that in some applications, electric motors cannot completely replace internal combustion engines, so the problem still restricts them.

But now, the opportunity for this reform has come.

Thinking of this, Manager Zhou couldn't help but sigh with emotion:

"Currently, our electric motors can be regarded as very mature, especially high-power electric motors, so I think our opportunity to overtake on corners in the power field is here."

"The quality of domestically produced engines is not good. Everyone knows this. It's just that they think that this is only restricting the development of our national industry. They don't know that this actually restricts the development of our national defense technology."

"A tank's engine is the heart of a tank. At present, diesel engines are the main engines, and gas turbines are only used by Americans, but their advantages cannot be ignored."

"Compared with diesel engines, gas turbines have many advantages. In addition to the aforementioned small size, high unit power, and fast start-up, gas turbines are also much more reliable than diesel engines in most environments. Due to the transmission components of gas turbines less and relatively simpler in structure, so it can avoid the interference of many external factors in the process of doing work.”

"Because its principle is similar to that of a jet engine, it takes in air and then mixes it with mist-like oil for combustion. After generating high-temperature and high-pressure gas, it drives the impeller blades to rotate and do work. Therefore, its low-temperature start-up performance is also excellent, and there is no difficulty in low-temperature start-up of diesel engines. According to the test, the AGT-1500 of the US military can even start normally at -30°C."

"Compared to them, we are still a little bit worse."

"Stop, stop, you keep talking so much, is it your plan?"

"We're going to go straight to the motor!"

"Electric motor? But the current battery can't meet such requirements, right?" Wang Feng wondered, after all, let's not talk about the difference between a battery weighing several tons and an explosive pack, the price alone is not a number, okay? good.

"No, no, no, we didn't plan to use batteries, we only planned to use electric motors, and then use a heat recovery system to further improve the response speed of the power system."

"After all, compared with diesel engines and gas turbines, whether it is torque or response speed, electric motors crush them!"
