AUBURN HILLS, Mich.,
March 12, 2019 /PRNewswire/
-- BorgWarner introduces its next generation of cam torque
actuators – intelligent cam torque actuation (iCTA) – delivering
better fuel economy and reduced emissions with its innovative
technology. Leading the industry in the future of hydraulic cam
phasing, iCTA blends the best attributes of cam torque actuation
(CTA) and torsional assist (TA) phaser technologies.
"As global emissions regulations become more stringent, iCTA is
an important advancement which enables manufacturers to tune engine
calibrations for reduced emissions and improved fuel economy
without sacrificing optimal performance," said Joel Wiegert, Morse Systems president,
BorgWarner Inc. "iCTA works with any engine architecture, and is an
ideal solution for inline four-cylinder engines with low or varying
cam torque energy. It's a great addition to our industry-leading
variable cam timing product portfolio."
Technologies that make the airpath more efficient and tunable
are key to meeting future emissions regulations, and iCTA is a key
enabler. By combining the benefits of CTA and TA, iCTA
provides fast cam phasing throughout the engine operating range,
reducing emissions and improving fuel efficiency while maintaining
optimal vehicle performance. BorgWarner's intelligent cam torque
actuator allows the engine to be tuned for optimal opening and
closing of the valves to maximize airflow when the engine needs it,
and minimize it when it doesn't. iCTA enables this across a variety
of engine types and is especially effective when applied to inline
four-cylinder (I4) engine applications with varying cam torque
energy. By recirculating oil within the actuator, iCTA reduces oil
demand and engine parasitic losses over competing I4 solutions,
resulting in increased fuel economy, lower emissions and improved
vehicle performance.
As the cam shaft spins, it oscillates, due to cam torque, the
iCTA captures this cam torque and uses its energy to augment the
energy from the engine oil pump. The technology partners with
front-mounted variable force solenoid controls and a center-mounted
spool valve contained within the bolt mounting the phaser to the
camshaft. iCTA integrates all necessary features within the
existing centerbolt architecture to allow interchangeability with
an existing CTA or TA cam phaser.
iCTA performs consistently across all engine speeds, has compact
packaging and is a cost-effective solution to best manage airflow
for a variety of driving conditions, from cold-starts to highway
cruising.
This technology is expected to first appear on a variety of
vehicles from two major vehicle manufacturers in China and North
America in 2019 and 2020
