Cam torque actuated (CTA) phasers with mid-position lock and integrated center bolt
Variable Cam Timing (VCT)
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.
