BorgWarner launches new VCT Technology for Hyundai Motor Company

BorgWarner’s Variable Cam Timing (VCT) Technologies Improve Engine Efficiency, Performance and Fuel Economy

Auburn Hills, Michigan, October 13, 2016 – BorgWarner supplies the first combination of its variable cam timing (VCT) technologies, including its patented cam torque actuated (CTA) phasers with mid-position lock and integrated center bolt, for Hyundai’s improved Lambda II V-6 engines. The 3.0- to 3.8-liter gasoline engines debuted in the 2016 Hyundai Genesis EQ900, G90, G80 and Aslan as well as the Kia K7. Featuring an integrated center bolt for easy assembly, BorgWarner’s CTA phasers with mid-position lock respond faster than traditional VCT systems, enabling engine designers to employ new calibration strategies that contribute to the engine’s 1.7 percent increase in fuel economy.

“No other supplier offers this combination of high-performance VCT technologies. As more automakers recognize the ease of integration and opportunities in engine calibration, we expect demand to escalate,” said Joe Fadool, President and General Manager, BorgWarner Morse Systems. “We are pleased to launch the first combination of our latest VCT technologies on Hyundai’s improved Lambda II engine, along with localized manufacturing and engineering support.”

BorgWarner’s CTA phasers take advantage of the existing torsional energy in the valve train to actuate faster and operate under a wider range of engine speeds and temperatures than conventional VCT systems. Using BorgWarner’s variable force solenoid, CTA phasers require less engine oil, which also reduces parasitic losses and enables oil-actuated variable valve lift systems to operate with an expanded duty cycle. BorgWarner’s patented mid-position lock technology allows an increased range of camshaft positioning with a default stop at an intermediate position within the expanded range of travel. Unlike competitive models that require active control to return to default position and relock, BorgWarner’s passive mid-lock technology ensures failsafe return to
the mid-park position for reliable engine starts in any operating condition. The integrated
center bolt simplifies engine production on the assembly line.

In addition to VCT technologies, BorgWarner supplies the engine timing chain
system for many Hyundai engines, including the Kappa, Gamma, Theta and Lambda.
