DETROIT, April 9 /PRNewswire/ -- The Schaeffler Group - a leading
global manufacturer of rolling bearings and linear products - is presenting
two technical papers during the annual 2007 Society of Automotive Engineers
(SAE) World Congress held in Detroit from April 16 to 19. The company will
discuss its research surrounding new fuel-saving technologies through two
presentations at the Congress and one written paper, which will be released
for purchase at the event.
As an engineering partner and supplier to almost all automobile
manufacturers and major suppliers worldwide, the Schaeffler Group's
Automotive Division offers a variety of products for the entire vehicle,
including engine, transmission, chassis and accessory drives. Through its
INA, FAG and LuK brands, the company's products provide reduced fuel
consumption and lower emissions for customer vehicle applications.
The Schaeffler Group's first paper at the SAE World Congress is titled
"High Performance Electric Camshaft Phasing System" and will be given on
Wednesday, April 18 at 3:45 p.m. by Jens Schaefer and Jeff Balko from INA
Schaeffler KG. This presentation addresses a new ultra-fast electrically
operated cam phasing system that allows rapid adjustment of cam timing for
all engine speeds and engine temperatures. This allows an aggressive
calibration of the cam timing, hence improving fuel economy and engine
response. The system can even be used during engine start-up, hot idle or
at sub-zero temperatures. It can ideally be combined with novel combustion
concepts, such as direct injection (DI) or homogeneous charge compression
ignition (HCCI).
Additional fuel economy benefits can be gained by adapting the engine
oil system to the reduced requirements. The Schaeffler Group will discuss
its innovative solution to electrical camshaft phasing in this presentation
and show test results that demonstrate the systems abilities.
The company's second paper, "Active Fuel Management(TM) (AFM)
Technology: Hardware Development on a 2007 GM 3.9L V-6 OHV SI Engine," will
be presented jointly with representatives from General Motors Corp. on
Thursday, April 19 at 1:30 p.m.
Authors of the paper are: David Kehr; James Westbrook III; Henning
Karbstein; and Mario Kuhl from the Schaeffler Group, INA, and Mark
Stabinsk; William Albertson; and Jim Tuttle from GM. The presentation will
discuss the new AFM system and the modifications and packaging challenges
of adapting the AFM system to the 2007 3.9L V-6 engine. This approach to
cylinder deactivation can lead to fuel economy improvements of up to 5 to 7
percent.
A third paper, "Front End Accessory Drive Vibration Control Solutions
for Engines with Cylinder Deactivation," will be offered for purchase
throughout the show at the SAE bookstore. This paper investigates and
recommends vibration control solutions based on the increase of torsional
energy in the front end accessory drive, which results from deactivating
cylinders in an engine.
