Back in 2001, nineteen years ago, Volkswagen Group announced that the new Bugatti car under development was officially named Bugatti    veyron    eb   16.4. Among them, “veyron” is to commemorate Pierre   veyron, a engineer who has made outstanding contributions in the history of the Bugatti brand. It once drove the Bugatti 57s car to win the 1939 Le Mans 24 Hours Championship. “eb” is the abbreviation of its founder Etori Bugatti, and “16.4” means that its engine has 16 cylinders and 4 turbochargers.

That's right, even with 16 cylinders and 4 turbochargers, more than 1000 horsepower!

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

Seeing this, Zhao Feng was inexplicably more excited!

Although I was just looking at the information, Zhao Feng could still feel how hard the engineers racked their brains to contemplate to meet the motivation standards!

Maybe this is called craftsman spirit!

It was like I had seen a great craftsman on a small ruined station before.

Zhao Feng continued to watch!

In order to meet the power standards, the engineers creatively cleverly connected the two V8 engines together. By drawing on the clever cylinder layout and simple intake and exhaust design of the VR6 engine, they almost perfectly controlled the engine size and weight, and designed a w16 engine as exquisite as a handicraft. In addition, in order to further squeeze the power limit of this w16, the engineers used four turbochargers in the form of hanging outside the cylinder, successfully making its power increase reach 92kw/l.

To be honest, when Zhao Feng saw this, he seemed to think that all this didn’t seem particularly difficult!

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

When the engine is developed, how to adapt this engine to the body of the car has become the biggest problem!

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

First of all, ordinary steel engines cannot withstand such intense movements, so Bugatti uses titanium alloy materials in aerospace technology to create important components such as piston rings, cylinders, etc. At that time, Bugatti engineers said that all the components of the engine were as exquisite as jewelry!

Next is the engine test!

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

To put it more vividly, the huge heat generated during operation of this w16 engine can heat a burger in 0.02 seconds, or meet the daily heating of 100 families.

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

The ultra-high exhaust temperature often burns the exhaust pipe red, and flames continue to gush out of the Bugatti Veevo exhaust hole during the road test.

Later, the engineers changed the exhaust to the material of titanium alloy, and also designed a brand new cooling system. The cooling system consists of 10 radiators of different sizes. Each radiator has 600 grilles, which are made by Bugatti engineers using 30 parts to weld and polish. Each radiator is 15 hours in production.

The complex cooling system is combined with a larger intake capacity, which meets the heat dissipation needs of Bugatti Viaeon.

More cylinders mean higher probability of problems. Traditional knock sensors installed on the cylinder block obviously cannot meet the precise monitoring of each cylinder. Bugatti adopts ion flow detection technology. The mixture will release charged ions during combustion, and the quantity is determined by the mass of the combustion. The ion flow control device will apply a constant voltage on the spark plug after the ignition is over, so that the spark plug becomes a sensor, through which the ion flow can be measured.

The powerful power must correspond to the same powerful braking system. The conventional brake disc is naturally incompetent. The engineers chose a composite brake disc made of carbon ceramic fiber and titanium alloy. It is not only huge in size, but also uses complex processes such as cross-drilling on the surface, which increases the limit working temperature of this brake disc to 1,800 degrees, far exceeding the limit temperature of 1,300 degrees for the brake disc of a general sports car.

The brake calipers are made of lightweight titanium alloy, and the number of pistons in the front and six on the rear makes this brake system extremely powerful. Bugatti officially claims that it can apply a maximum braking force of 1.3g to the vehicle. However, even so, the engineers are still worried. They are facing a "monster" with a speed of more than 400km/h.

After repeated discussions and experiments, the engineers finally created an air brake system for Viahan. When the vehicle is driving at a high speed of 220km/h, the tail wing rises by about 15°, and when the speed reaches 370km/h, the tail wing drops to only about 2°. When the vehicle brakes at full force, the tail wing will rise to 55° within 0.4 seconds and bends up at 135°, instantly providing Viahan with a maximum braking force of 0.68g.

The braking force is almost equivalent to the full braking capability of a hatchback. Finally, under the combined action of conventional braking and air braking system, it only takes 2.3 seconds for Bugatti Veyron to slow down from 100km/h to stationary, and the brake distance is stable at about 31.4 meters. It takes less than 10 seconds for Bugatti Veyron to slow down from 100km/h to stationary.

mts Technology Company provides Viahan with a full set of electronic components. By calculating factors such as body posture, wind speed, driving trajectory, etc., they control the tail to complete the calculations and make corresponding adjustments in a very short time. It can be said that for performance, Viahan has been armed to the teeth.

The brake system is designed, but this alone is not the whole of the brake!

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

To this end, Bugatti and Michelin cooperated to create high-performance tires exclusive to Viatron based on aircraft tire technical standards, with the exaggerated width of the rear wheels reaching an exaggerated 14.5 inches (about 365mm). Tire rubber is laid by workers layer by layer, and each layer of pattern is almost exactly the same. The price of four Viatron tires is more than 20,000 US dollars.

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

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

The Bugatti brand, although it is an old high-end car manufacturer with a history of hundreds of years!

But obviously, after Bugatti's second resurrection, this Bugatti Veevo completely started again, and all the designs reached a new level.

If such a Bugatti could not make a big splash, Zhao Feng would probably be even more surprised!

Zhao Feng felt a little ups and downs for a moment.

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