Toyota's headquarters in Japan's R&D center, a large number of top engineers of the entire Toyota company temporarily abandoned their original work tasks, all concentrated on the R&D center to disassemble and study 60 Dongchen cars, 60 Dongchen cars of different models, Toyota will divide these vehicles into batches, the first batch of dismantling, is S1, S2, S3, S3C these four models each two, a total of eight cars.

In the largest workshop of the R&D center, skilled technicians began to disassemble the eight cars, first dismantling the body shell and seats, and secondly, the mechanics dismantled the whole car only the power unit and the drive device, the drive experts focused on the four-wheel drive technology used on the Dongchen S3C, while other experts focused more on engine technology.

In fact, Dongchen's most eye-catching technology is its powerful engine manufacturing process, the quality of the engine used is about 20% lighter in density than ordinary aluminum alloy, coupled with strong pressure resistance and high heat resistance, so the engine made of this material can be thinner than that made by ordinary engines, so that the weight can be reduced by about 10%.

After the engine was disassembled, Toyota's engine experts carried out a full range of monitoring of the three engines of Dongchen, and they even disassembled the entire engine into individual parts, and conducted detailed research on each part. They were ready to do it again, they thought that since Dongchen could make this thing, then Toyota must be able to do it too!

Toyota's chief engineer for gasoline engines is Hideyoshi No, 53, who studied at the Massachusetts Institute of Technology. Later, he went to RWTH Aachen University in Germany for further study, and after returning to China, he has been working in engine research and development at Toyota for 20 years. Several of Toyota's classic engines are from his hands, and Toyota's 1.8 Hybrid engine, which has just won the environmental award, is from his hands. Ye Yingji, who was originally full of ambition, was shocked without a trace of all his self-confidence when Dongchen Automobile was made public to the world, and he was also deeply aware of the great changes that Dongchen engine technology would bring to the world's automobile industry, and he knew that the current Dongchen was still a baby dragon, if he was given enough time to develop, the world's car brands would one day be slaughtered by him, and Toyota currently wanted to do everything he could. Keeping up with Dongchen's technology, otherwise once Dongchen has a strong production capacity, its own market will be squeezed to the extreme.

No, Hidekichi took the lead in arranging all the parts of the Dongchen 1.4 engine neatly on the huge work table, and then picked up calipers and magnifying glasses to observe these parts in detail. In the Dongchen engine, even one of the crankshaft connecting rod parts is perfectly done, and even the cut metal edges are neatly like the blades that have been polished countless times, not a little frizz and burrs, on the contrary. Toyota can't do such a perfect degree of precision in these details, and none of the world's automakers can, so their cars have to go through a run-in period before they can polish the machine to a normal level after they just roll off the assembly line.

In terms of parts alone, it can be seen that Dongchen currently has ultra-high-precision machining capabilities, which they have far surpassed Toyota and all other competitors.

Ye Yingji knows that Toyota took back these cars, all of which have just come off the assembly line, and some of them have not even driven a hundred kilometers in the hands of consumers, take the S1 engine that they disassembled, and the car's kilometer meter only ran 80 kilometers and was bought back by Toyota at a high price, 80 kilometers, no matter what, it is impossible to polish the parts so perfectly, which shows that Dongchen's manufacturing accuracy is indeed extraordinary. …,

The cylinder wall of the engine was thin so that no Hideyoshi couldn't believe it, he ordered his engineers to put another S1 engine that had not been disassembled on the test bench, with the maximum speed, to see what kind of bearing capacity this engine can reach, when the S1 1.4 engine was sent to the test bench, the testers continued to give oil, so that the speed was kept at 9,000 rpm, and it continued to run for 20 minutes, and everything was running well.

Ye Yingji asked the testers to increase the speed by 10,000, and the engine ran again for 20 minutes at 10,000 rpm, and there was still no problem.

Ye Yingji was shocked, and continued to increase the speed, and finally, when the car reached 12,000 rpm, the heat dissipation of the engine could no longer keep up with such a high speed, and the temperature of the engine rose sharply, and after running for less than ten minutes, the temperature reached 170 degrees, and finally the cylinder burst and stalled.

The results of the test shocked Ye Yingji, such a thin cylinder wall, the withstand strength is much higher than that of ordinary materials, thick cylinder wall engine, ordinary engine, if the temperature reaches 120 degrees, basically not far from the cylinder explosion, and, ordinary engine, 6,000 rpm, will not run for long, the engine will be scrapped, and such a 1.4 engine, in the state of no actual power output, the speed can reach 12,000 in a short time.

In addition, the resistance strength of other crankshafts and gear parts is far more than that of ordinary vehicles, under the requirements of Ye Yingji, engineers monitored the gears and other transmission parts of Dongchen Automobile, and found that the materials they used made the strength and wear resistance of the gears increased by at least half, this material seems to mean lower maintenance costs and higher service life in the eyes of ordinary people, but Ye Yingji saw the great significance at a glance, if it is a high-power engine driven by a large weight, Then the strength of the transmission system is a very important indicator!

The higher the strength of the transmission system, the greater the force that moves from the power part to the greatest extent, if it is a heavy machinery, such as a tank or a train, if the strength of the transmission system is not enough, then the strong power has not even been transmitted to the wheels, and the transmission parts have been damaged first, and the higher the strength. The longer its service life is.

Take Japan's Shinkansen high-speed railway, emergency braking at high speed, a pair of brake shoes will soon be worn and scrapped standards, the reason is that the material strength of the brake shoes is not enough; It's like an SUV stuck in a quagmire, or a steep slope that wants to move forward. Need a lot of power, this time, if you slam on the accelerator. A large amount of fuel is injected into the engine, which quickly burns into vigorous power, which is then discharged to the drivetrain. But what happens when the wheels are so deep that they can't even turn?

As a result, the huge power of the engine cannot be released on the four wheels of the car, and in the end, the huge force cannot disappear for no reason, there must be a part to withstand the force that cannot be released, when it is the gearbox, in this case. A few feet of throttle down, the gearbox will definitely burn out, for the simple reason that the strength of the gears cannot withstand such a huge force.

In another case, if the strength of the drivetrain is greatly improved. As soon as the force in the engine is exerted, the drivetrain responds effortlessly, and eventually, all the forces are concentrated on the wheels, so that two phenomena occur. Two cars got stuck in the same mud pit, one stubbornly rushed out, and the other either had its wheels running out forever or it burned out the gearbox in place.

This is also the fundamental reason why the S3C can easily rush out when it is tested in the mud swamp, while the A7 can only lie in the mud pit.

The strength of the transmission system is a hard indicator of the SUV off-road type, which is a worldwide problem in military manufacturing, Ye Yingji did not think that China has mastered such a powerful material technology, and contacted Toyota's CEO for the first time, and Toyota's senior management also sent the relevant parameter data to the Defense Agency for the first time. …,

Originally, the Defense Agency did not care about their new discovery on a civilian car, but after looking at the specific data, the people of the Defense Agency were taken aback, and the top management immediately interviewed Mitsubishi Heavy Industries and held a secret meeting in the Defense Agency.

Mitsubishi Heavy Industries is Japan's largest military industrial enterprise, basically from the sky and the earth, they have dabbled in all kinds of military equipment, when they look at such a parameter report on the material, the first thing they think about is the fucking military application.

Engineer Xi 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 multiply the mobility and passing capacity of the tanks and warships, but then again, if this material is obtained by the United States or Russia, it will definitely have a great effect, but China is not afraid, their engine production has always been a hard injury, for example, the tolerance of the current forecast is 50, and the engine strength of the United States, Germany, Russia and other countries can reach between 60-65." , but the Chinese engine, even below 50, even if they are given a tolerance of 100 materials, will not make any fundamental changes. ”

Although he did not forget to sarcastically ridicule China, the Xi engineer said: "We are currently lacking such new materials, destroyers, submarines power performance continues to improve, the tonnage is getting larger and larger, the strength requirements for the transmission system are also constantly improving, high power drives large propellers to do rapid rotation under the condition of high underwater resistance, once the strength of its transmission parts is improved, the power performance of the existing ship will be greatly improved." ”

The Defense Agency also attached great importance to the views of Mitsubishi experts, and blurted out the question, "Is it possible for us to make a replica of this material?" ”

"It's hard." The material expert of the same industry said: "The material is not a product, if we want to imitate other people's bicycles, we can basically imitate a rough picture according to the gourd painting scoop, but if we want to imitate other people's materials, it is much more difficult, it takes a long time to study and analyze, just like the depleted uranium armor of the United States, Russia has studied it for so many years, and has not studied a reason." ”

"What about imports?" The personnel of the Defense Agency spoke: "This material was first discovered on the Dongchen automobile, and it is also that Dongchen has the strength to produce it, or has the channel to obtain this material, you can change your identity and negotiate with the personnel of Dongchen, if you can, we will introduce this material at a high price, of course, if you can get the technology of this material, it would be great." ”

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

The person in charge of the Defense Agency said: "This material is of great strategic significance, no matter what the cost or any method is, we must find a way to get it!" ”

Director Liu reported Zhang Wenhao to borrow Dongfeng and BAIC two off-road vehicle production lines to the superiors, because the two sides have launched a higher level of high-power diesel engine cooperation, so the senior management does not attach importance to these two automobile production lines, originally these two production lines are national investment, national use, now basically out of a semi-idle state, it is a waste to throw there, since Dongchen has channels to engage in first-class automobile manufacturing technology, then they will accept it, and there will inevitably be better and newer results.

After getting a positive reply from the high-level, Director Liu personally asked Zhang Wenhao to go to these two automobile companies for on-the-spot investigation, Zhang Wenhao does not have high requirements for these two production lines, he will provide them with some technical information and requirements for the chassis, there is no difficulty in the production of suspension system, coupled with the output of new technology, these two companies can definitely meet their own requirements, as for the manufacture of the car body is simpler, Zhang Wenhao does not do supercars, what he needs is the car body made of conventional materials and technology, time, You only need to provide them with the model information and drawings themselves, and they can naturally produce them directly.

Other core components are still produced by themselves, and when the results of both sides are integrated, the car can basically be rolled offline in Dongfeng and BAIC's production lines, and other irrelevant parts such as seats, air conditioning, and hydraulic assistance can be purchased directly from other suppliers.

The new SUV will be defined as the C series, Zhang Wenhao is initially preparing to launch three models, but the classification of SUVs is not as dense as sedans, so Zhang Wenhao's three models will cover the price range from 201,200,000, for example, C1 positioning 20-400,000, C2 positioning 40-700,000, C3 positioning 70-1.2 million, the price range is basically similar to Audi Q3, Q5, Q7 three levels.

C1 hardware configuration will start from the 2.0T engine, C2 will use 2.5T, C3 will use 3.0-3.6T, the main focus is the ability to pass through the whole road, never to other brands like the sheep's head to sell dog meat, sell some can only run in the city and high-speed on the so-called off-road SUV, as long as the ability to pass is strong, with a fashionable and excellent appearance, basically can capture all the users who are inclined to SUV.

When Zhang Wenhao began to borrow two new production lines to expand Dongchen's market, the relevant person in charge of Mitsubishi's domestic purchasing company contacted Long Yue.
