super learning system

In the R&D center of Toyota's headquarters in Japan, a large number of top engineers in the entire Toyota company temporarily abandoned their original work tasks and concentrated on the R&D center to dismantle and research 60 Dongchen cars. The 60 Dongchen cars were of different models.

First, Toyota divided these vehicles into batches. The first batch to be dismantled was...two of each of these four models, a total of eight vehicles.

In the largest workshop of the R&D center, skilled technicians began to dismantle the eight vehicles. The first thing they dismantled were the body shells and seats. Secondly, the technicians disassembled the entire vehicle, leaving only the power unit and drive.

Device and drive experts focus on the four-wheel drive transmission technology used in Dongchen S3C, while other experts focus more on engine technology.

In fact, Dongchen's most eye-catching technology is its powerful engine manufacturing process. Compared with ordinary aluminum alloys, the material used in the engine is about 20% lighter in density. In addition,

It has strong pressure resistance and high heat resistance, so engines made of this material can be thinner than ordinary engines, which can reduce the weight by about 10%.

After the engine was disassembled, Toyota's engine experts conducted comprehensive monitoring of Dongchen's three engines. They even disassembled the entire engine into individual parts and conducted detailed research on each component. Japan's

Che uses this kind of all-round research and mastery of other people's technologies, and finally through his own transformation and innovation, he finally excels and occupies a place in the global market. Now, they are ready to repeat the same tricks. They believe that since Dongchen can make this

If you can make something, then Toyota can do it too!

The chief engineer of Toyota's gasoline engine is named Ono Eikichi. He is 53 years old and studied at the Massachusetts Institute of Technology. He later went to RWTH Aachen University in Germany for further study. After returning to China, he has been working in engine research and development at Toyota for 20 years now.

Several of Toyota's classic engines came from his hands. The Toyota... engine that Toyota just won the environmental protection award came from his hands. Ono Eikichi, who was originally very proud, when Dongchen Motors was made public to the world,

All his self-confidence was shattered without a trace, and he was also deeply aware of the huge changes that Dongchen's engine technology would bring to the world's automobile industry. He was even more aware that Dongchen now was still in his infancy.

If you give him enough time to develop, all the car brands in the world will one day be slaughtered by him. The most important thing for Toyota at the moment is to try every means to match Dongchen's technology, otherwise once Dongchen has the skills

With strong production capacity, your own market will be squeezed to the extreme.

Ono Eikichi took the lead in placing all the parts of the Dongchen 1.4 engine neatly on the huge work table, and then picked up the caliper and magnifying glass to observe these parts carefully. In the Dongchen engine, even a small crankshaft connection

The rod parts are all made perfectly. Even the cut metal edges are as neat as a knife blade that has been polished countless times. There is not a single frizzy or burr. On the contrary, Toyota simply cannot achieve such perfect accuracy in these details.

No car manufacturer in the world can do this to such a degree, so their cars have to go through a running-in period before they can polish the machines to normal levels right after they roll off the assembly line.

From the parts alone, it can be seen that Dongchen currently has ultra-high-precision processing capabilities. In this regard, they have far surpassed Toyota and all other competitors.

Ono Eikichi knew that the cars that Toyota took back had just rolled off the production line, and some of them had not even been driven a hundred kilometers in the hands of consumers. Take the S1 engine he disassembled as an example, the mileage of the car

The watch only ran for 80 kilometers before it was bought back by Toyota at a high price. For 80 kilometers, it would be impossible to polish the parts to such perfection. This shows that Dongchen's manufacturing accuracy is indeed extraordinary.

The engine's cylinder wall was so thin that Ono Eikichi couldn't believe it. He ordered his engineers to install another S1 engine that had not yet been disassembled on the test bench, and use the maximum speed to see what the engine's carrying capacity could be.

What level has it reached? When the S1 1.4 engine was sent to the test bench, the testers kept adding oil to keep the speed at 9,000 rpm. It continued to run for 20 minutes. Everything in the machine was running well.

Ono Eikichi asked the tester to increase the engine speed to 10,000 rpm, and the engine ran again for 20 minutes at 10,000 rpm, and there was still no problem.

Ono Eikichi was shocked and continued to increase the speed. Finally, when the car's speed reached 12,000 rpm, the engine's heat dissipation could no longer keep up with such a high speed. The engine's temperature rose linearly. After running for less than ten minutes,

After that, the temperature reached 170 degrees, and finally the cylinder exploded and stalled.

The test results shocked Ono Eikichi. The withstand strength of such a thin cylinder wall is much higher than that of ordinary materials. For engines with thick cylinder walls, ordinary engines will basically explode if the temperature reaches 120 degrees.

It's not far away. Moreover, an ordinary engine will not run for long at 6,000 rpm before the engine is scrapped. However, such a 1.4 engine can actually rotate at a speed in a short time without actual power output.

Reached twelve thousand.

In addition, the endurance strength of other crankshaft and gear components is also far higher than that of ordinary vehicles. At the request of Ono Eikichi, engineers monitored the gears and other transmission components of Dongchen Automobile. The monitoring found that the materials they used made

The strength and wear resistance of the gears have been increased by at least half. In the eyes of ordinary people, this material seems to mean lower maintenance costs and longer service life, but Ono Eikichi can see the significance at a glance. If it is

A high-power engine drives a large weight, so the strength of the transmission system is a very important indicator!

The higher the strength of the transmission system, it means that the force from the power part to the moving part can be retained to the greatest extent. If it is heavy machinery, such as tanks, trains, if the strength of the transmission system is not enough, then the powerful power will not even be able to

When transmitted to the wheel, the transmission components will be damaged first, and the higher the strength, the longer its service life will be.

Take Japan's Shinkansen high-speed railway as an example. When emergency braking is performed at high speed, a pair of brake shoes will soon be worn to the scrap standard. The reason is that the material used to make the brake shoes is not strong enough; another example is an SUV with a deep

If you are stuck in a quagmire, or on a steep slope, and you want to move forward, you need strong power. At this time, if you step on the accelerator, a large amount of fuel will be injected into the engine, which will be quickly burned into vigorous power, and then output to the transmission system. However,

The wheel is deeply sunk and cannot even turn. What will be the result?

As a result, the huge power of the engine cannot be released on the four wheels of the car. In the end, the huge force cannot disappear for no reason. There must be a part to withstand this unreleased force. The first one to bear the brunt is the gearbox. Here

In this case, if you press the accelerator a few times, the gearbox will definitely burn out. The reason is simple: the strength of the gear cannot withstand such a huge force.

In another situation, if the strength of the transmission system is greatly improved, as soon as the vigorous force in the engine comes out, the transmission system will respond effortlessly, and finally, all the force will be concentrated on the wheels. In this way, there will be

Two phenomena. Two cars fell into the same mud pit, and one car rushed out tenaciously. The other car either kept its wheels spinning forever, or burned out the gearbox in place.

This is also the fundamental reason why when the s3c was tested in the muddy ground, it could easily rush out, but the a7 could only lie down in the muddy pit.

The strength of the transmission system is a hard indicator of the off-road type of SUV, and it is also a global problem in military industry manufacturing. Ono Eikichi did not expect that China would master such powerful material technology, so he immediately contacted Toyota's CEO, and

Toyota executives also sent relevant parameter information to the Defense Agency as soon as possible.

The Defense Agency originally didn't care about their new discovery on a civilian car, but after seeing the specific data, the people at the Defense Agency were shocked. The senior officials immediately interviewed Mitsubishi Heavy Industries and held a secret meeting at the Defense Agency.

Mitsubishi Heavy Industries is Japan's largest military enterprise. Basically, they are involved in all kinds of military equipment from the sky to the ground. When they saw such a parameter report on materials, the first thing they thought of was him.

Damn military applications.

The chief engineer of Mitsubishi Heavy Industries said: "If the Chinese side uses this technology, their tanks and warships can be equipped with more powerful engines, which will double the mobility and passing ability of the tanks and warships. But that said

Come back, if this material is obtained by countries like Germany or Russia, it will definitely have great effects. However, China is not afraid. Their engine production has always been a flaw. For example, the tolerance of the material today is

50. The engine strength of countries such as the United States and Russia can reach 60-65, but China's engines are even lower than 50. Even if they are given materials with a tolerance of 100, there will be no fundamental changes.

"

Although he did not forget to ridicule China, the chief engineer immediately said: "We are currently lacking such new materials. The power performance of destroyers and submarines continues to improve, and their tonnage is getting larger and larger, which requires the strength of the transmission system.

It is also constantly improving. High power drives large propellers to rotate rapidly under high underwater resistance. Once the strength of its transmission components is improved, the power performance of existing ships will be greatly improved."

The Defense Agency also attached great importance to the opinions of Mitsubishi experts and blurted out: "Is it possible for us to imitate this material?"

"It's difficult." The materials expert in the same field said: "Materials are not products. If we want to imitate other people's bicycles, we can basically imitate them by following the gourd. But if we want to imitate other people's materials, then

The difficulty is much greater, and just research and analysis will take a long time. Just like the United States' depleted uranium armor, Russia has been studying it for so many years, but it has not found a reason."

"What about importing?" The personnel from the Defense Department asked: "This material was first discovered in Dongchen Automobile. In other words, Dongchen has the ability to produce or has channels to obtain this material. You can change your identity and go to

Let’s negotiate with Dongchen’s staff. If possible, we will introduce this material at a high price. Of course, if we can obtain the technology for this material, that would be great.”

The relevant person in charge of Mitsubishi said: "We have many localized shell companies in China, most of which are engaged in international procurement. We can find a company that has no relationship with Mitsubishi or even Japan on the surface and go to Dongchen.

Let’s get in touch with someone.”

The person in charge of the National Defense Agency said: "This material is of great strategic significance. No matter what the cost or any method, we must find a way to get it... Director Liu told Zhang Wenhao that Zhang Wenhao wanted to borrow the two off-road vehicle production lines of Dongfeng and BAIC.

The report was reported to the superior leaders. Since the two parties have already launched a higher-level cooperation on high-power diesel engines, the senior management does not attach much importance to these two automobile production lines. Originally, these two production lines were invested by the state and used by the state. Now they are basically out of stock.

It is a waste to leave it in a semi-idle state. Since Dongchen has channels to obtain first-class automobile manufacturing technology, if they accept it, they will inevitably produce better and newer results.

After getting a positive reply from the top management, Director Liu personally asked Zhang Wenhao to go to the two automobile companies for on-site inspections. Zhang Wenhao did not have high requirements for these two production lines. He would provide them with some technical information and requirements for the chassis, suspension and

There is no difficulty in system production. With the output of new technologies, these two companies can definitely meet their own requirements. As for the manufacturing of car bodies, it is even simpler. Zhang Wenhao does not make supercars. What he needs are conventional materials and processes.

When the time comes to make the car body, you only need to provide them with the vehicle model information and drawings, and they will naturally start production directly.

Other core components will still be produced by ourselves. By then, once the results of both parties are combined, the car can basically roll off the production lines of Dongfeng and BAIC. Other insignificant parts such as seats, air conditioners, hydraulic assists, etc.

Just purchase directly from other suppliers.

The new SUV will be defined as the C series. Zhang Wenhao is initially planning to launch three models. However, the classification of SUVs is not as intensive as that of cars, so Zhang Wenhao's three models will cover the price range from 200,000 to 1.2 million.

For example, c1 is positioned at 200,000-400,000, c2 is positioned at 400,000-700,000, and c3 is positioned at 700,000-1.2 million. The price range is basically similar to the range of Audi q3, q5, and q7.

The hardware configuration of c1 will start from 2.0t engine, c2 will use 2.5t, and c3 will use... The main focus is the ability to pass on all roads, and will never be like other brands. Some of them can only be sold in urban areas and highways.

As long as the so-called off-road SUVs have strong capabilities and stylish and excellent appearance, they can basically capture all users who are attracted to SUVs.

And just when Zhang Wenhao started to borrow two new production lines to expand Dongchen's market, the relevant person in charge of a domestic purchasing company of Mitsubishi contacted Long Xiaoyue.!~!
