Sign In to Become a Legendary Hero

Time goes back to 2001. Nineteen years ago, the Volkswagen Group announced that the new Bugatti car under development was officially named bugattiveyroneb164. The "veyron" was to commemorate the outstanding engineer ierreveyron in the history of the Bugatti brand. It was won by the Bugatti 57s. Champion of the 24 Hours of Le Mans in 1939. "Eb" is the acronym of its brand founder Ettori Bugatti, and "164" means its engine has 16 cylinders and 4 turbochargers.

That's right, even with a 16-cylinder, 4 turbocharger, more than 1,000 horsepower!

This w16 engine created by 8 engineers has become the heart of all Bugatti sports cars from today!

Seeing this, Zhao Feng was inexplicably more excited!

Although just looking at the information, Zhao Feng can still feel how hard the engineers were trying to achieve the motivation!

Maybe this is called craftsmanship!

It's like seeing the craftsmen of a great country on Xiaopo Station before.

Zhao Feng continued watching!

In order to reach the power standard, the engineers creatively connected the two v8 engines together. By learning from the ingenious cylinder layout and simple intake and exhaust design of the vr6 engine, the size and weight of the engine were almost perfectly controlled, and the w16 was designed as exquisite as a handicraft. engine. In addition, in order to further squeeze the power limit of this w16, the engineers installed four turbochargers in the form of extra-hung outside the cylinder, and successfully made the power per liter reach 92kw.

To be honest, seeing this, Zhao Feng seems to feel that all this doesn't seem to be particularly difficult!

In fact, the super difficulty brought by this engine is mentioned in the following information!

When the engine was developed, how to adapt this engine to the car body became the biggest problem!

Solving these problems is the most difficult problem in the design of Bugatti Veyron!

First of all, ordinary steel engines cannot withstand such violent movements. Therefore, Bugatti uses titanium alloy materials in aerospace technology to build important parts such as piston rings and cylinder blocks. At the beginning, Bugatti's engineers even boasted that all parts of the engine are the same. Jewelry is generally exquisite!

Next is the engine test!

For the first time, engineers tried to make this w16 engine run at full load. The engine with a nominal power of 1001 horsepower can actually burst out at least 3000 horsepower, of which two-thirds of the energy needs to be converted into heat and discharged, and the exaggerated heat burned out the experiment. The exhaust device on the ceiling of the room even almost ignited the entire laboratory!

To put it more vividly, the huge heat generated during the operation of this w16 engine can heat a hamburger in 002 seconds, or meet the daily heating of 100 households.

The problem of too high heat also affects the exhaust system!

The extremely high exhaust gas temperature tends to burn the exhaust pipe red. During the road test, the Bugatti Veyron's exhaust hole constantly spews out of flames.

Later, the engineers changed the exhaust gas into a titanium alloy material, and also designed a new cooling system. The cooling system is composed of 10 radiators of different sizes, each with 600 grilles, by Bugatti engineers It is made by welding and polishing 30 parts, and the production time of each radiator is 15 hours. x

Complicated heat dissipation system with larger intake air volume meets the heat dissipation requirements of Bugatti Veyron.

More cylinders means a higher probability of problems. The traditional knock sensor installed on the cylinder block is obviously unable to accurately monitor each cylinder. Bugatti uses ion flow detection technology, and the mixture will be released during the combustion process. The quantity of charged ions is determined by the quality of combustion. The ion current control device will apply a constant voltage to the spark plug after ignition, so that the spark plug becomes a sensor through which the ion current can be measured.

Powerful power must correspond to the same powerful brake system. Conventional brake discs are naturally incapable. Engineers chose composite brake discs made of carbon-ceramic fiber and titanium alloy. Not only are they huge in size, they also use cross-drilling on the surface. The complex technology has increased the limit working temperature of this brake disc to 1800 degrees, far exceeding the limit temperature of 1300 degrees for ordinary sports car brake discs.

The brake calipers are made of lightweight titanium alloy. The number of pistons in the front eight and six in the rear makes this braking system extremely powerful. Bugatti officially claims that it can apply a maximum of 13g of braking force to the vehicle. But even so, the engineers are still not at ease, they are facing a "monster" with a speed exceeding 400kh. x

After repeated discussions and experiments, the engineers finally built an air brake system for Weihang. When the vehicle is driving at a high speed of 220kh, the tail rises about 15°, and when the speed reaches 3h, the tail drops to only about 2°. When the vehicle is fully braking at this time, the rear wing will rise to 55° and tilt at 135° within 04 seconds, instantly providing Weihang with a maximum braking force of 068g.

This braking force is almost equivalent to the full braking capacity of a hatchback. UU reading www. uukanshu.com finally under the combined action of conventional braking and air braking system, the Bugatti Veyron decelerated from 100khh to standstill in only 23 seconds, and the braking distance was stable at about 314 meters. second.

ts technology company provides a complete set of electronic components for Weihang. They control the tail wing to complete the calculation and make corresponding adjustments in a very short time through the measurement of body attitude, wind speed, driving trajectory and other factors. It can be said that Weihang has Was armed to the teeth.

The brake system is designed, but these alone are not all of the brakes!

You should know that there are only four tires in direct contact with the ground. Once the tire limit is exceeded, all braking performance is just empty talk.

To this end, Bugatti cooperated with Michelin to create exclusive Weihang high-performance tires based on aircraft tire technical standards. The rear wheel width reached an exaggerated 145 inches of approximately 365. The tire rubber is manually laid layer by layer by the workers, and the pattern on each layer is almost the same. The price of four Weihang tires is more than US$20,000.

Seeing this, Zhao Feng couldn't help but sigh!

No wonder Bugatti Veyron became the fastest super gun vehicle in the world as soon as it was born!

Although the Bugatti brand is an veteran high-end car manufacturer with a history of over a hundred years!

But obviously, after the second resurrection of Bugatti, this Bugatti Veyron is completely restarted, and all the designs have reached new heights.

If such a Bugatti couldn't make a blockbuster, Zhao Feng would be even more surprised!

Zhao Feng had dim sum ups and downs for a while.

Those foreign supercar manufacturers have indeed developed by accumulating technology step by step!

It seems that domestic car dealers still have some way to go! div
