Eaton TVS™ Supercharger Featured On 2010 Audi S4/S4 Avant

SOUTHFIELD, Mich. … Diversified industrial manufacturer Eaton Corporation today announced that its Twin Vortices Series™ (TVS™) supercharger has been selected to power Audi’s 3.0 liter TFSI V6 engine available in the automaker’s new 2010 S4 and S4 Avant midsize class vehicles.

Eaton’s TVS supercharger compliments Audi’s redesigned 3.0 liter TFSI V6 engine, the newest member of the Audi V-engine family, with a quicker throttle response, delivering 333 horsepower, in addition to achieving an average fuel economy of 24 miles per gallon.

“Extensive tests of the V6 conducted by Audi engineers reveal the TVS supercharger provides optimal vehicle performance,” said Joao Faria, president of Eaton’s Powertrain and Specialty Controls Business. “When combined with direct injection, the TVS surpasses twin turbochargers in packaging, starting performance and responsiveness.”

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.
