Chapter 296 greediness

Toyota is located in the R & D center of the headquarters of Toyoda Daur. A large number of top engineers of the entire company temporarily left behind their original tasks and concentrated on the R & D center to disassemble and research 60 Dongchen cars. The 60 Dongchen cars are of different models, so Toyota divided these cars in batches. The first batch of cars to be disassembled was S1, S2, S3 and s3c, four models in total Eight cars.

In the workshop with the largest area of the R & D center, skilled technicians began to disassemble the eight vehicles, first of all, the car body shell and seats were disassembled, second, the whole vehicle was disassembled by technicians only with power device and driving device, driving experts focused on the four-wheel drive technology adopted by Dongchen s3c, while other experts paid more attention to engine technology.

In fact, Dongchen's most eye-catching technology is his powerful engine manufacturing process. Compared with the ordinary aluminum alloy, the material used in the engine is about 20% lighter in density. In addition, it has strong compression resistance and high heat resistance. Therefore, the engine made of this material can be thinner than that made by the ordinary engine. In this way, it can be reduced by about 10 %Weight of.

After the engine was disassembled, Toyota's engine experts carried out all-round monitoring on the three engines of Dongchen. They even disassembled the whole engine into separate parts, and carried out detailed research on each part. In that year, Dongou car used this kind of all-round research and mastering other's technology, and finally through its own transformation and innovation, the most important thing is to Now, they are ready to do the same thing again. They think that if Dongchen can make this thing, then Toyota can!

The chief engineer of Toyota's gasoline engine is Yingji Ono, 53 years old. He studied at MIT, and then went to Aachen University of technology in Germany for further study. After returning home, he has been working in Toyota's engine research and development. It has been 20 years since now. Several classic engines of Toyota come from his hands. Toyota, which just won the Environmental Protection Award, 1.8

hybrid D engine is from his hands. At the time when Dongchen automobile was released to the public, all his self-confidence was lost. He also realized that the technology of Dongchen engine would bring great changes to the world automobile industry. He knew that now Dongchen is a young dragon still in its infancy. If it can give him enough Enough time to develop, the world's auto brands will be slaughtered by him one day. At present, the most important thing for Toyota is to do everything to keep up with Dongchen's technology, otherwise once Dongchen has a strong production capacity, its market will be squeezed to the extreme.

Yingji Ono took the lead in arranging all parts of Dongchen 1.4 engine on a large worktable, then picked up a caliper and a magnifying glass, and observed these parts carefully. In Dongchen engine, even a small crankshaft and connecting rod component is perfectly made, and even the metal edges are neat as the blades that have been polished countless times, but no one can be found On the contrary, Toyota can't achieve such perfect accuracy in these details. There's not a single car manufacturer in the world that can do it, so their cars just come off the production line must go through the running in period before they can polish the machine to the normal level.

As can be seen from the parts alone, Dongchen now has the ability of ultra-high precision processing, which is far beyond Toyota and all other competitors.

Xiaoye Yingji knows that the cars that Toyota has collected are just coming off the line. Some of them haven't even driven 100 kilometers in the hands of consumers. Taking the S1 engine that he disassembled for example, the kilometer meter of the car only runs 80 kilometers, and Toyota bought it back at a high price. 80 kilometers, it's impossible to polish the parts so perfectly It can be seen that the manufacturing accuracy of Dongchen is indeed extraordinary.

The cylinder wall of the engine is so thin that Yingji Ono can't believe it. He orders his engineers to install another S1 engine that hasn't been disassembled on the test bench, and use the maximum speed to see what the bearing capacity of this engine can achieve. When the S1 1.4 engine is sent to the test bench, the tester constantly gives oil to keep the speed at 9000 rpm After twenty minutes of continuous operation, the machine is running well.

Ono Yingji asked the tester to increase the speed to 10000, and the engine ran at 10000 rpm for another 20 minutes, still without any problems.

.

The test results shocked Ono Yingji. The resistance strength of such a thin cylinder wall is much higher than that of an engine made of ordinary materials and thick cylinder wall. If the temperature of an ordinary engine reaches 120 degrees, it is not far from the cylinder bursting. Moreover, an ordinary engine, under the condition of 6000 revolutions, will not run for a long time, and the engine will be scrapped Engine, in the absence of actual power output, the speed can reach 12000 in a short time.

In addition, the endurance strength of other crankshaft and gear parts is far greater than that of ordinary vehicles. At the request of Ono Yingji, engineers monitored the gears and other transmission parts of Dongchen automobile. They found that the materials they used increased the strength and wear resistance of gears by at least half. In the eyes of ordinary people, this material seems to mean lower maintenance Cost and higher service life, but Ono Yingji can see the great significance at a glance. If it is a high-power engine driving a large weight, then 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 maximum extent. If the strength of the transmission system is not enough for heavy machinery, such as tanks and trains, then the powerful power has not even been transmitted to the wheels, so the transmission parts have been damaged first, and the higher the strength, the longer the service life.

In the case of Shinkansen high-speed railway in Dong'Er, in case of emergency braking at high speed, a pair of brake shoes will soon be worn to the scrap standard. The reason is that the material strength of brake shoes is not enough. Another example is a SUV that is stuck in the mud, or has a steep slope. If you want to move forward, you need strong power. At this time, if you step on the accelerator, a lot of fuel will be injected into the engine, and the engine will burn rapidly into vigorous power, and then output it to the transmission system. However, if the wheels are stuck, or even unable to rotate, what will be the result at this time?

As a result, the huge power of the engine can not be released on the four wheels of the car. In the end, the huge power cannot disappear without any reason. There must be a part to bear the force that can not be released. The first thing to bear is the gearbox. In this case, the gearbox will burn off when several oil doors go down. The reason is very simple. The strength of the gear cannot bear it Such a huge force.

In another case, if the strength of the transmission system is greatly enhanced and the vigorous force in the engine comes out, the transmission system will respond without any effort. Finally, all the forces will be gathered on the wheels. In this way, two phenomena will appear. Two cars are planted in the same mud pit, and one car is indomitably rushed out, and one car is always idling, Or, it burned the gearbox in place.

That's why when s3c was tested in the mud, it could easily rush out, while A7 could only lie in the mud pit.

The strength of the transmission system is a hard indicator of SUV off-road type, which is also a worldwide problem in military industry manufacturing. Yingji Ono didn't expect China to have such a strong material technology. He contacted the CEO of Toyota at the first time, and the senior management of Toyota also sent the relevant parameter information to the defense department at the first time.

The defense department didn't care about their new discovery in a civil car, but after reading the specific data, the people in the defense department were shocked. The senior management immediately interviewed Mitsubishi Heavy Industries and held a secret meeting in the defense department.

Mitsubishi Heavy Industry is the largest military enterprise in dongdau. Basically, they are involved in all kinds of military equipment from the sky to the ground. When they see such a parameter report on materials, the first thing they think about is the damn military application.

The chief engineer of Mitsubishi Heavy Industries said: "if the military of China uses this technology, their chariots and warships can be equipped with more powerful engines, which will increase the mobility and passing capacity of chariots and warships. However, if this material is obtained by virtue or e-country, it will certainly have a great effect, but China However, the country is not afraid. Their engine production has always been a hard injury. For example, now the material tolerance is 50, and the engine strength of countries such as Germany and Russia can reach 6065, but the engine of China is even lower than 50. Even if the material tolerance reaches 100, there will be no fundamental change. "

Although we don't forget to satirize China, the chief engineer Xuan even said: "at present, we are lack of such new materials. The power performance of destroyers and submarines is constantly improving, the tonnage is growing, and the strength requirements of the transmission system are also constantly improving. The large propeller driven by high power makes rapid rotation under the condition of high resistance underwater, and its transmission Once the strength of moving parts is improved, the power performance of existing ships will be greatly improved. "

The Defense Department also attached great importance to the views of Mitsubishi experts and asked, "is it possible for us to imitate this material?"

"It's hard." "Materials are not products. If we want to imitate other people's bicycles, we can basically imitate a rough idea based on the gourd ladle. However, if we want to imitate other people's materials, it's much more difficult. It will take a long time just for research and analysis, just like the depleted uranium armor in the United States, which has been studied by e country for so many years, but it hasn't There's a reason for that. "

"What about imports?" The Defense Department said: "this material was first found on Dongchen's car. That is to say, Dongchen has the strength to produce or has the channel to obtain this material. You can change your identity and negotiate with Dongchen's personnel. If you can, we will introduce this material at a high price. Of course, if you can get the technology of this material, it will be better "

"We have a lot of local Fazi Gong in China," said the head of Mitsubishi
