In addition to the Volkswagen Beetle and Porsche 911 that are still in production now, this year, and in 1978, other models that still use air-cooled engines are estimated to be impossible to find in the world.

Why there are so few air-cooled engines is because the cooling method of air cooling is not as controllable as that of liquid cooling, and the influence of driving speed and temperature is much greater than that of liquid cooling, and on the racing track, only Porsche, a super wonder, the Porsche family's insistence on air-cooled and horizontally opposed engines can be described as "stubborn".

Nobuhiko Kawamoto's concerns were certainly not unfounded, as CBX1000's engine was originally designed for the surrounding empty and barrier-free straddle motorcycles, and the huge heat from the cylinder's work was carried away by the heat dissipation fins that were dozens of times the surface area of the cylinder and the flow of air when it was windward.

Originally, two straight six were put together into a V12, the heat dissipation is exaggerated enough, the car you designed is still a mid-rear-drive model, the engine is in the "trunk" behind the seat, the working environment of the engine increases badly, are you afraid that the engine will not overheat and explode?

Chen Geng smiled and asked rhetorically, "Mr. Kawamoto, do you think we won't take this issue into account?"

"Oh?"

The little devil's temper attacked, Kawamoto Nobuhiko raised his eyebrows, and he didn't believe that Chen Geng could solve the problem of heat dissipation of the passive air-cooled engine in a confined space: "How are you going to solve this problem? Are you going to transform this engine into a water-cooled one?"

"Water cooling? That's too troublesome," Chen Geng waved his hand: "Actually, the solution is very simple, I plan to put a shell on the outside of the engine block, and install two fans to turn the engine into forced air cooling." ”

Nobuhiko Kawamoto's face was red and white, and he couldn't wait to find a crack in the ground to get into!

That's right, since there is no way to meet the requirements through passive air cooling after adjustment, then turn it into active air cooling, such a simple way, I didn't expect it?

What is Forced Air Cooling?

Internal combustion engines can be divided into two categories in terms of cooling methods, one is water cooled engine and the other is air cooled engine.

Water cooling is also called liquid cooling, which everyone is familiar with, and 99.999% of the engines on the car are cooled in this way.

Air cooling is divided into active and passive two, passive air cooling is well understood, this is a cooling method that does not have active heat dissipation, we see on the street domestic 125CC, 150CC straddle motorcycles are passive air cooling, the engine is covered with a lot of heat dissipation fins, relying on the surface area is dozens of times the surface area of the cylinder heat dissipation fins and windward to take away the heat of the engine, CBX1000 is also this kind of passive air-cooled engine.

The active air cooling is more fun, this cooling method is designed for the engine that can not be cooled by the wind, or called the way of hitting the wind, simply put, is to design a shell at the head position of the engine, and then install a fan on one or both sides of the shell, by blowing cold air on the cylinder or pumping air out to create air flow to make the engine get the right working temperature.

Most of the scooters we can see in China are equipped with this kind of forced air-cooled engine, and the Volkswagen Beetle and Porsche 911 that are now on sale (1978) are all cooled in this way.

From a practical point of view, designing a suitable shell and installing a fan on the outside of the cylinder head of the passive air-cooled engine can realize the engine from passive air-cooled to active air-cooled, and the cooling effect will be better than that of the engine originally designed as active air-cooled, because the cylinder surface of the active air-cooled engine is usually not designed with heat sink fins or only has very little heat dissipation deception, while the passive air cooled heat sink fins are much more.

Thinking about the expression on his face, Fernandez must have been stupid in his eyes, right? Maybe Fernandez wondered if the "technical Honda" lived up to its name......

Thinking of this, Nobuhiko Kawamoto had an urge to slap himself twice: What is this?

————————————

“...... That's the way it is, and after reviewing their proposals, I think they have a good chance of succeeding, and Mr. Fernández and his team members have very good technical ......

I deliberately rode in the car driven by Mr. Fernandez to experience his stance skills, the results shocked me very much, in my opinion, Mr. Fernández has the same level of driving as a professional driver, I mean, he can already participate in professional car events in Dongying, but he is still a long way from winning the championship, and he is far from being an international racing driver, but his level can indeed participate in some professional car events......

For these reasons, I think that by working with Fernandez, we can better promote Honda in the North American market, and I think we can provide technical support to Fernandez's team, and we can provide them with the original materials related to the CBX1000 engine under the premise of signing a non-disclosure agreement, and even have our developers help them improve and upgrade this V12 engine......

I thought for a long time about Fernandez's request to introduce our engine, and I thought that I could agree to him conditionally, and of course, some restrictions were necessary......

The reason why I use fax is that there are so many things to say that I can't say clearly on the phone, but in short, I hope that the club will consider it carefully. ”

It took more than ten minutes for the secretary to finally finish reading the fax that Nobuhiko Kawamoto sent back to Toei from North America overnight, and there was silence in the huge conference room, and the executives of Honda Motor Co., Ltd. did not speak, quietly savoring the contents of Nobuhiko Kawamoto's fax, and there was a copy of this fax in front of him.

"Gentlemen, let's talk about it. After a moment of silence, Kawashima, the then president of Honda Motor Co., Ltd. and a disciple of Soichiro Honda, the founder of Honda, spoke.

"I trust Kawamoto-kun's judgment. ”

"Kawamoto is right, the Detroit Modified Car Grand Prix is very well-known, and this is a very good publicity opportunity for Honda. ”

"But there is a premise for this, that is, only by getting a good name can Honda get good publicity, and if that Fernandez ends up with bad results, it will hurt Honda's brand power a lot......"

............

Honda Motor Co., Ltd.'s executives have their own opinions, some oppose and some support, and no one can convince anyone.

In the face of everyone's arguments, Kawashima did not express his position, and in the end, his eyes fell on Kume Yoshi, the vice president of Honda Motor Co., Ltd., who is also the next president of Honda Motor Co., Ltd., his junior brother, and the second disciple of Soichiro Honda: "Kume-kun, what do you think?"

Kume Shizhi bowed slightly and said in a deep voice, "I agree with Kawamoto-kun's opinion. ”

"Oh?" Kawashima seemed a little surprised.

Kume said: "In my opinion, Honda's support for Fernandez this time is actually an investment behavior, and since it is an investment behavior, it is necessary to allow the existence of risks. ”

After saying this, he kept silent.

"Then let's do it," Kawashima pondered for a moment, and finally nodded: "Now Honda, it needs to make a name for itself in the North American market, and it is necessary to let Americans know that Honda can not only be a fuel-efficient family car, but also have achievements in the field of racing, which represents the peak of technology, and can also have achievements that others cannot match." ”

Obviously, working with Fernandez is much less expensive than working with others.

————————————

Chen Gengke didn't know that Honda Motor Co., Ltd. had made a decision so quickly, and based on his understanding of the little devil, he felt that Honda Motor Co., Ltd. could give him a quick answer within a month.

Chen Geng, who knows the temperament of the little devil very well, is not in a hurry at all, anyway, from the beginning he didn't expect to get much from Honda, in line with the spirit of "Honda is willing, Lao Tzu will earn it, Honda is stingy." Lao Tzu didn't lose anything", what should be done, for example, now, in Chen Geng's opinion, entertaining Todd and a few of them is much more important than caring about when the little devil agrees to his conditions......

"Fernandez, we've all thought about it," Todd explained his intentions on behalf of the used car dealers in Detroit, "We are ready to fully introduce your used car sales system and fully cooperate with you in used car inspection." ”

Todd followed, followed by several other nods.

"Congratulations to everyone," Chen Geng nodded with a smile: "Everyone has made a correct decision, and I wish us a happy cooperation in the future." ”

For Todd's decision, Chen Geng is not surprised, since the last meeting with Todd, Chen Geng has been staring at the transaction situation of Detroit's second-hand car market, under the impact of Fernandez Company, compared with last month, Detroit's second-hand car dealers are more sad this month, but Fernandez Company, daily sales hit a new high, not only created the highest daily transaction record of 53 cars, but also created a daily average transaction record of 38.2 vehicles, and the monthly transaction volume accounted for 12.76 of the total monthly transaction volume of used cars in Detroit%, the entire used car market in Detroit was in an uproar.

In this case, anyone who is not stupid can see that Detroit's used car dealers have no choice but to learn from Fernandez if they want to survive.
