the time goes back to 2001. 19 years ago, Volkswagen Group announced that the Bugatti new car under development was officially named Bugatti Veyron eb16 4. "Veyron" is to commemorate Pierre Veyron, a meritorious Engineer in the history of Bugatti brand. It once drove Bugatti 57s to win the championship of Le Mans 24-hour endurance race in 1939. "EB" is the acronym of its brand founder etori Bugatti, "16.4" means that its engine has 16 cylinders and 4 turbochargers.
Yes, even with a 16 cylinder, 4-turbocharger, more than 1000 horsepower!
This w16 engine created by 8 engineers has become the heart of all Bugatti sports cars since today!
Seeing here, Zhao Feng was inexplicably more excited!
Although only looking at the data, Zhao Feng can still feel how hard those engineers racked their brains to reach the power standard!
Maybe this is called craftsman spirit!
It's like I've seen a great craftsman on a small broken station before.
Zhao Feng then looked down!
In order to meet the power standard, the engineers creatively connected the two V8 engines together, almost perfectly controlled the engine size and weight by drawing lessons from the ingenious cylinder layout and simple intake and exhaust design of VR6 engine, and designed the exquisite w16 engine as a handicraft. In addition, in order to further squeeze the power limit of this w16, the engineer has attached four turbochargers outside the cylinder in the form of hanging, and successfully increased its power to 92 KWL.
To be honest, seeing here, Zhao Feng seems to think all this is not particularly difficult!
In fact, the next information mentioned the super difficulty brought by this engine!
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 Bugatti Weihang!
First of all, the ordinary steel engine simply can't withstand such intense sports, so Bugatti uses titanium alloy in aerospace technology to build important parts such as piston ring and cylinder block. At the beginning, Bugatti's engineers boasted that all parts of the engine are as exquisite as jewelry!
Next is the engine test!
Engineers tried to make this w16 engine run at full load for the first time. The engine with rated 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 energy. The exaggerated heat burned out the exhaust device on the ceiling of the laboratory, and even almost ignited the whole laboratory!
Figuratively speaking, the huge heat generated during the operation of this w16 engine can heat a hamburger 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 gas temperature often burns the exhaust pipe red. During the road test, the exhaust hole of Bugatti Weihang keeps gushing out.
Later, the engineers changed the exhaust into titanium alloy and designed a new cooling system. The cooling system is composed of 10 radiators of different sizes. Each radiator has 600 grids, which are welded and polished by Bugatti engineers with 30 parts. The manufacturing time of each radiator is 15 hours.
The complex heat dissipation system combined with greater air intake meets the heat dissipation needs of Bugatti Weihang.
More cylinders means a higher probability of problems. It is obvious that the traditional knock sensor installed on the cylinder block can not meet the accurate monitoring of each cylinder. Bugatti adopts ion flow detection technology. The mixture will release charged ions during combustion, and its quantity is determined by the combustion quality. The ion flow control device will release charged ions after ignition, A constant voltage is applied to the spark plug 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 selected the composite brake disc made of carbon ceramic fiber and titanium alloy. It is not only large in size, but also uses complex processes such as cross drilling on the surface, so that the limit working temperature of this brake disc is raised to 1800 degrees, Far exceeds the 1300 degree limit temperature of the brake disc of ordinary sports cars.
The brake calipers are made of light titanium alloy. The number of pistons in the front eight and the rear six makes the brake system extremely powerful. Bugatti officially claims that it can apply the maximum braking force of 1.3g to the vehicle. However, even so, engineers are still worried that they are facing a "monster" with a speed of more than 400kmh.
After repeated discussions and tests, the engineers finally built a set of air braking system for Weihang. When the vehicle runs at a high speed of 220kmh, the tail rises by about 15 °, and when the speed reaches 370kmh, the tail drops to only about 2 °. When the vehicle is fully braked at this time, the tail wing will rise to 55 ° and tilt 135 ° in 0.4 seconds, which can instantly provide Weihang with a maximum braking force of 0.68g.
This braking force is almost equivalent to the full braking capacity of a hatchback. Finally, under the joint action of conventional braking and air braking system, Bugatti Weihang only takes 2.3 seconds to decelerate from 100kmh to standstill, the braking distance is stable at about 31.4 meters, and it takes less than 10 seconds to decelerate from extreme speed above 400kmh to standstill.
MTS technology company provides Weihang with a full set of electronic components. Through the calculation of body attitude, wind speed, driving track and other factors, they control the tail to complete the calculation and make corresponding adjustments in a very short time. It can be said that Weihang has been armed to the teeth for performance.
The design of the braking system is completed, but these are not all the brakes!
You know, 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 company to create exclusive Viagra's high-performance tires with aircraft tire technical standards, and the rear wheel width reached an exaggerated 14.5 inches (about 365mm). The tire rubber was manually paved layer by layer by workers, and the patterns of each layer were almost identical. The price of four Viagra tires was more than 20000 US dollars.
Seeing here, Zhao Feng couldn't help sighing!
No wonder Bugatti Viagra has become the fastest super gun truck in the world since its birth!
Bugatti brand, although it is an old high-end automobile manufacturer with a history of more than 100 years!
But obviously, after the second resurrection of Bugatti, this Bugatti Viagra is completely restarted, and all the designs have reached a new height.
If such Bugatti can't make a splash, Zhao Feng will be even more surprised!
Zhao Feng was a little agitated for a while.
Those foreign super running manufacturers have indeed accumulated technology step by step!
It seems that domestic car dealers still have a way to go!
