Audi Selects Eaton TVS™ Supercharger To Power Fuel Efficient V6
SOUTHFIELD, Mich. … Diversified industrial manufacturer Eaton Corporation today announced that its Twin Vortices Series™ (TVS™) supercharger has been chosen by Audi to power the automaker’s all-new 3.0 liter TFSI V6 engine.
“Audi engineers did extensive comparative testing and found our new TVS supercharger provided superior throttle response and low-end torque coveted by drivers,” said Joao Faria, president of Eaton’s Powertrain and Specialty Controls Business. “Additionally, when paired with direct injection and enhanced transmission ratio, the TVS supercharger helps the engine achieve 290 hp with an average fuel economy of nearly 24 miles per gallon.”
The supercharged 3.0 liter TFSI V6 is a member of Audi’s family of ultramodern V engines and will go into production later this year. Audi has a tradition of developing supercharged engines dating back to grand prix racing cars in the 1930s.
The Eaton TVS is an all-new Roots-type positive displacement supercharger that features twin four-lobe rotors that are twisted 160-degrees. The intermeshing, high-speed rotor design pumps air directly into the engines intake system that when mixed with fuel creates more power. By comparison, the original Eaton supercharger features three lobes twisted 60 degrees. The fourth lobe and added twist, when combined with redesigned air inlet and outlet ports, creates a smooth, highly efficient flow of air into the engine and has improved noise and vibration characteristics.
