BorgWarner says it is expanding its engine timing business in Korea, by supplying its advanced cam torque actuated (CTA) variable cam timing (VCT) technology to Hyundai and Kia vehicles powered by 3.0- to 3.8-litre V6 gasoline engines. The company says its CTA phasers with mid-position lock technology respond faster than traditional VCT systems and enable greater valve timing control over a broad range of engine speeds.
The 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, claims the company.
