Chapter 938 The only Bugatti that Insists on a 16-Cylinder Engine!

Back in 2001, nineteen years ago, the Volkswagen Group announced that the new Bugatti new car under development was officially named bugattiveyroneb164, where "veyron" was to commemorate the distinguished engineer ierreveyron in the history of the Bugatti brand, who drove the Bugatti 57s to win the race. 1939 Le Mans 24 Hours champion. "eb" is the acronym of Ettore Bugatti, the founder of the brand, and "164" means that its engine has 16 cylinders and 4 turbochargers.

That's right, even with 16 cylinders, 4 turbos, more than 1000 hp!

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

Seeing this, Zhao Feng was inexplicably a little more excited!

Even though he was just looking at the data, Zhao Feng could still feel how hard the engineers had racked their brains in order to achieve the power goal!

Maybe this is called craftsmanship!

It's like the craftsmen of the big country that I have seen on Xiaopo Station before.

Zhao Feng continued to read!

In order to achieve the power standard, the engineers creatively connected the two V8 engines together. By borrowing 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 a delicate handicraft. engine. In addition, in order to further squeeze the power limit of this w16, the engineer installed four turbochargers outside the cylinder in the form of additional plugs, and successfully made the liter power reach 92kw.

To be honest, seeing this, Zhao Feng seems to think that all this is not particularly difficult!

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

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

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

First of all, ordinary steel engines cannot withstand such violent motion at all, so Bugatti uses titanium alloy materials in aerospace technology to create important parts such as piston rings and cylinder blocks. The jewelry is generally beautiful!

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. Two-thirds of the energy needs to be converted into heat energy and discharged. The exaggerated heat burned out the experiment. The exhaust device in the ceiling of the room even nearly ignited the entire laboratory!

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

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

The ultra-high exhaust gas temperature will often burn the exhaust pipe to red, and the Bugatti Veyron exhaust hole constantly spewed out flames during the road test.

Later, the engineers changed the exhaust to be made of titanium alloy, and also designed a new cooling system. The cooling system consists of 10 radiators of different sizes. Each radiator has 600 grilles. It was designed by Bugatti engineers. Welded and ground from 30 parts, each radiator took 15 hours to make. x

The complex cooling system and the larger air intake can meet the cooling needs of the Bugatti Veyron.

More cylinders means a higher probability of problems. The traditional knock sensor installed on the cylinder block obviously cannot meet the precise monitoring of each cylinder. Bugatti adopts the ion current detection technology, and the mixture will be released during the combustion process. Charged ions are produced, and the quantity is determined by the mass of the 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.

Strong power must correspond to the same powerful braking system. Conventional brake discs are naturally incompetent. Engineers chose composite brake discs made of carbon ceramic fiber and titanium alloy, which are not only huge in size, but also use cross-drilling on the surface. The complex process has raised the extreme working temperature of this brake disc to 1,800 degrees, far exceeding the 1,300-degree limit temperature of ordinary sports car brake discs.

The brake calipers are made of lightweight titanium alloy, and the number of pistons in the front eight and six in the rear makes the braking system extremely powerful. Bugatti officially claims that it can apply a maximum braking force of 13g to the vehicle. But even so, the engineers are still worried, they are facing a "monster" with a top speed of more than 400kh. x

After repeated discussions and tests, the engineers finally built an air brake system for Weihang. When the vehicle is running 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 braked at this time, the rear wing will rise to 55° in 04 seconds and tilt up to 135°, which can instantly provide a maximum braking force of 068g for Weihang.

This braking force is almost equivalent to the full braking capacity of a hatchback. In the end, under the combined action of conventional braking and air braking system, Bugatti Veyron decelerates from 100kh to standstill in only 23 seconds, the braking distance is stable at about 314 meters, and it takes less than 10 seconds to decelerate from a top speed of over 400kh to standstill.

ts technology company provides a full set of electronic components for Weihang. They control the rear wing to complete the calculation and make corresponding adjustments in a very short time by measuring the body posture, wind speed, driving trajectory and other factors. It can be said that for the performance, Weihang has already Armed to the teeth.

The braking system design is completed, but these are not the whole of the brakes!

You must 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 Veyron high-performance tires based on aircraft tire technical standards. The rear wheel width reaches an exaggerated 145 inches and about 365 inches. The tire rubber is manually laid by workers layer by layer, and the pattern of each layer is almost identical. The price of four Weihang tires is more than 20,000 US dollars.

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

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

Although the Bugatti brand is an old high-end car manufacturer with a history of hundreds of years!

But obviously, after the second resurrection of Bugatti, this Bugatti Veyron has started all over again, and all the designs have reached a new height.

If such a Bugatti can't be a blockbuster, Zhao Feng will be even more surprised!

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

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

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