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