Eaton Introduces
New Supercharger
There are improvements.
Then there are improvements.
The TVS2 supercharger just launched by Eaton ( eaton.
com ) is in the latter category.
Consider: the new supercharger—thanks to rotary profle
changes that reduce the clearance between rotors to
minimize internal leakage, rotor twist modifcations
that shift peak efciency for overall fuel economy
improvement, and new porting features that eliminate
unnecessary air compression—provides a 10 to 16%
improvement in isentropic efciency in targeted operating
zones compared to Eaton's own TVS R410 product.
Says Brian Contat, product director, Boosting, Eaton
Vehicle Group, "The latest innovation within our boosting
portfolio"—the TVS2—"delivers on the key areas that our
customers have the most interest in, including efciency,
weight reduction, improved engine performance, and
the ability to better package supercharger devices within
existing and future architectures."
The new supercharger's low-speed airfow has been
improved by more than 30%, which contributes to
increased torque at low engine speed. The unit is 25%
lighter than the previous generation supercharger.
One ideal application for the TVS2 is in combination
with a turbocharger, with the supercharger located after
the turbo. To handle the high
pressure, there are specifc seals
deployed, and there is a ball
bearing system that enables
temporary speeds up to 30,000
rpm, or 25% more than Eaton's
current units.
Because the higher speeds and
pressures can result in NVH,
the TVS2 features a backfow
port that reduces noise without
afecting airfow or efciency.
There is a micro-perforated panel
that results in a decibel level
improvement of up to 8 dB at low
speeds.
A supercharger/turbo system
(a compound system) used in
a 2.0-liter engine could deliver
more than 350 lb-ft of torque and
380 hp, thereby, Eaton engineers
suggest, the ability to use even
small engines in large vehicles,
given the performance provided
by the setup.
p To help address the requirements for improved
fuel economy and performance, Eaton has
developed the TVS2 supercharger.
