Designed to maximize fuel economy and performance, variable cam timing optimizes the opening and closing of intake and exhaust valves throughout the engine operating range. Unlike traditional cam phasing methods, which typically use engine oil pressure to phase the camshaft, BorgWarner’s patented CTA technology utilizes the existing torsional energy in the valve train, similar to a hydraulic ratchet, to phase the camshaft. CTA cam phasers operate more quickly and under a wider range of engine speeds and temperatures than traditional oil pressure actuated cam phasers. In addition, CTA cam phasers are fully functional during engine starting, the critical time when a large percentage of engine emissions occur and before the catalytic converter is effective.

BorgWarner’s CTA variable cam timing technology earned a 2009 Automotive News PACE Award as well as an Automotive News PACE Innovation Partnership Award for collaboration with Ford on 2009 3.0-liter Duratec V6 engine.
