Siheyuan: Heavy Industry Revitalizes the Country

“That’s what we say, but how do we achieve it?

I know all about electronic devices nowadays."

Cao Tianwei curled his nose, obviously thinking that this matter was easy to say, but not optimistic about achieving it.

“That’s why we need to study the matching electronic control system.

Otherwise, is that research institute just for show?"

Fang wanted to refill the teacup in front of him with tea again.

"Have you ever thought about how long it will take to see results?"

Cao Tianwei put the cigarette on the ashtray, picked up the teacup, and just took a sip, his eyes lit up instantly.

"Just study it first, there will always be a time when the fog will be cleared and the moon will appear.

It’s just a matter of adding some programs to the electronic control system.

Moreover, if the motor is also involved in the acceleration phase, the current 9-meter acceleration time is over 6 seconds, and I think it can be reduced to 7 or seconds, or even shorter. "

Fang wanted to take the last puff of his cigarette and put it out in the ashtray.

Having said this, I suddenly remembered that naturally aspirated engines of the same displacement are more fuel-efficient, while turbocharged engines of the same power are more fuel-efficient.

There used to be a saying in the car circle: the rich drive naturally aspirated engines, the poor drive turbo engines, and the crazy drive automatic multi-engine engines.

What I mean is that rich people like to pursue large displacement.

Large-displacement engines have all advantages except for their high fuel consumption.

But turbocharging is different, it makes it possible for small-displacement engines to surpass large-displacement engines.

As for mechanical supercharging... Fang Xiang has never come into contact with it, so his knowledge of it is limited. It has basically not been popularized on a large scale in later generations, so I will not discuss it here.

It has been nine years since the 79 oil crisis. The high oil prices brought about by the post-oil crisis have subsided and oil prices have now returned to their historical lows.

Large-displacement engines are once again beginning to gain popularity.

Logically speaking, the BMW 2.0 Series is still using a 135 naturally aspirated engine. Although the power has exceeded 1.5 horsepower, with a length of nearly meters and a weight of tons, it is obviously a bit like a small horse pulling a big cart.

Even the 3.0 engine of the BMW 1.8 Series is actually a bit difficult to power with a body length of meters and a weight of nearly tons, judging from the perspective of future generations.

Improving power and horsepower seems to have become a very important issue facing us.

But Fang Xiang knew that another oil crisis would come in 90.

The large-displacement engine that had just begun to emerge was instantly suppressed and suppressed again.

This is also an important reason why Japanese cars have been rapidly occupying global market share since the 90s.

However, Japanese cars are now suppressed in North America, and are being crushed by BMW and GAC in Southeast Asia, South America, and Central and Eastern Europe.

It no longer has the grand occasion it had when it first took off.

If a hybrid car model could be launched in 90, and it coincided with the oil crisis, it might have really led to a trend.

“If it accelerates to 6 seconds, wouldn’t that be close to an F1 car?

Wow, if our BMW 3 Series and 5 Series could accelerate so fast, wouldn’t they sell like hot cakes?

You know, the 3-5-meter acceleration of the M7 and M is only a little over seconds. . . "

Just when Fang Xiang’s mind started to wander.

Cao Tianwei has already drunk two cups of tea.

He had to admit that Fang Xiang's brewed tea tasted better than his.

"If you want to achieve faster acceleration, there is actually another way, such as installing a turbocharger on the engine.

However, fuel consumption will be higher, parts requirements will be higher, costs will be much higher, and the failure rate will not be lower.”

Fang Xiang was a little hesitant about whether to bring out the turbocharging technology.

In fact, turbocharging is no longer a high-tech thing now. It was invented in 1905.

This technology was actually first used in airplanes and tanks.

In the 1960s, General Motors began experimenting with this technology on its own models.

But why wasn’t it promoted?

In fact, the reason is what I just said.

But except for the high fuel consumption, all other problems are minor problems for Fang Xiang.

After all, he had the technology and drawings of many turbocharged engines for later generations.

He has all the material requirements and specific indicators, it just depends on whether he wants to bring them out.

What? You ask about the materials?

Aren’t the material requirements for airplanes that can fly higher than those for car engines?

Fang Xiang has the authority to manufacture the country's top aircraft. Isn't it just a matter of making a phone call to get any material he wants?

The rest is just a matter of cost.

After all, this is not the era of overproduction in the 21st century, but an era of scarcity.

The environment is different, so the choices are naturally different.

In comparison, Fang thought for a long time and felt that it would be better not to let the automobile industry snatch the material cake from the aircraft industry.

The share is so small that it is barely enough for the airplanes themselves, and the automobile industry... let's put it off for a while.

"Turbocharging? That thing is technically difficult, has high material costs, and has a high failure rate. I don't think it's a good thing.

It’s better to self-absorb.

But speaking of which, when are you going to update the engine?

Now I feel that the power of BMW is not good enough. "

When Cao Tianwei heard the word "turbocharged", he shook his head faster than anyone else.

If Fang Xiang represents the black technology of future generations, then Cao Tianwei represents the current actual technological level in the country.

He said no, and it really was no.

Unless Fang wants to take action.

"Don't worry, nowadays oil is something that needs to be used less and less.

It would be better to study the tram industry.

Use electricity for starting and cooperate with the acceleration motor.

It would be even better if the motor could also get involved when cruising at high speed for a long time.

I don't know how much fuel this can save.

The cost is minimal.”

Fang thought about it for a long time and decided to put the issue of turbocharging aside for the time being.

In fact, what turbocharging can do, electric motors can also do, and even do better.

Directly skipping turbocharging and entering the era of motor assistance may not necessarily be a bad thing.

“What about the extended-range model?

The engine generates electricity to charge the battery, which is then driven by the electric motor.

It doesn't seem as reliable as the hybrid you said?"

Cao Tianwei nodded. In fact, there is already a saying that oil is the blood of the earth, which is a little less true.

Just like when Fang Xiang was a child, he often heard that oil would only last for fifty years.

By the time Fang wanted to go to school, there was still only enough oil for 50 years.

By the time Fang Xiang was 30 years old, all the gasoline cars had been replaced by electric cars, and some people still said that the oil would only last for 50 years.

Now that I think about it, it may not be a conspiracy of the West, and it is the same method used to deceive people about carbon emissions and carbon neutrality.

“Extended-range electric vehicles are actually a good direction.

However, the technical requirements are a level higher than hybrid.

Although it is said to be more fuel-efficient, the technical requirements are much higher.

I think we can set hybrid as the short-term goal, extended-range as the medium-term goal, and pure electric as the long-term goal.

This is more realistic.”

Fang Xiang picked up a piece of paper and made a list of the technical standards for hybrid vehicles.

In fact, the requirements for hybrid vehicles are indeed the lowest. All you need is four motors, a large battery, and an electronic control system.

There are more requirements for extended range. First of all, the battery is not enough to meet the long-range needs of the vehicle. At least it needs to be a large battery like that of later generations.

With large batteries as the basis, pure electric technology has actually reached the threshold.

However, for pure electric vehicles, the electronic control system is more complicated and the requirements are several levels higher.

On the contrary, the extended-range type with mechanical attachment is simpler.

"So what you mean is that the next generation of BMW will switch to a hybrid drive mode?"

Cao Tianwei stroked his chin and looked at the list of technical requirements listed by Fang Xiang.

He said with narrowed eyes.

"No, let GAC go out and explore the way first."

Fang Xiang chuckled.

Next generation BMW? BMW just changed its generation in 87. If the hybrid technology of 90 can be used, then there must be several new models, right?

Without saying anything else, let’s launch the Lexus CE200H first.

Hey, I’m going to take the path of your daily life and leave you with no way to go.
