Introduction:
The Super Sport Bugatti Veyron EB 16.4 is designed & developed by Volkswagen Group(Germany) and produced by Bugatti Automobiles SAS. The Super Sport version is the fastest road-legal production car in the world, with a top speed of 431.072 km/h. The original version has a top speed of 408.47 km/h.
It was named Car of the Decade (2000–2009) by the BBC television programme Top Gear.
Name Origin:
The car is named after French racing driver Pierre Veyron. The 16.4 refers to 16 cylinders and 4 turbochargers.
The state of art innovations behind remarkable styling and revolutionary mechanical engineering that made the Veyron really amazing from an engineer’s point of view.
HISTORY:
It was Ettore Bugatti, who at the beginning of the last century, first recognized the advantages of a 16 cylinder engine and then built one. Modelled after an early airplane engine, he combined two 8-cylinder blocks into a twin engine with, for those times, an astounding 250 horse power.
At the beginning of the second automobile century, it was again Bugatti, who has breathed life into 16 cylinder technology taking advantage of today’s high-tech engineering. The Veyron was designed by Hartmut Warkuss of Volkswagen.
Creating the Engine:
The Veyron's 16-cylinder monster engine produces 1200 horsepower for a top speed of more than 400 km/h.
Bugatti did two things to create a compact engine capable of producing 1200 hp. The first and most obvious thing is turbocharging.
Through the working principle of Turbochargers one easy way to make an engine more powerful without making the engine bigger is to stuff more air into the cylinders on each intake stroke. Turbochargers do that. A turbo pressurizes the air coming into the cylinder so the cylinder can hold more air.
If you stuff twice as much air in each cylinder, you can burn twice as much gasoline. In reality, it's not quite a perfect ratio like that, but you get the idea. The Bugatti uses a maximum turbo boost of 18 PSI to double the output power of its engine.
Special Features:
The special features of the Bugatti W-16 engine are amazing.
• The engine has four valves per cylinder, for a total of 64 valves.
• It has a dry sump lubrication system borrowed from Formula 1 race cars, along with an intricate internal oil path to ensure proper lubrication and cooling within the 16 cylinders.
• It has electronically controlled, continuously variable cam timing to create optimal performance at different engine rpm settings.
• It has a massive radiator to deal with all of the waste heat that burning 1.33 gallons of gasoline per minute can generate
Transmission:
The transmission is unique, in particular because it has to produce about twice as much torque as any previous sports-car transmission. It has:
• Seven gears
• A dual clutch system
• Sequential shifting
• A paddle-driven, computer-controlled shifting system
This computer-controlled system is identical to the sort of system found in a Formula 1 car or a Champ car. There is no clutch pedal or shift lever for the driver to operate -- the computer controls the clutch disks as well as the actual shifting. The computer is able to shift gears in 0.2 seconds.
It would be almost impossible for all of the torque available from the W-16 engine to flow out to just two wheels without constant wheel-spin. Therefore, the Veyron has full-time all-wheel drive. By applying the engine's power to all four wheels through a computer-controlled traction-control system, the car is able to harness all of the engine's horsepower, even at full acceleration.
