2009 Ford Escape to feature BorgWarner CTA technology

"As car makers strive to meet drivers' demands for performance and fuel economy while complying with increasingly stringent emissions regulations, the new BorgWarner CTA technology for variable cam timing has emerged as an important option for optimizing the method of achieving variable cam timing. The CTA technology is a great growth opportunity for BorgWarner," says Alfred Weber, president and general manager, BorgWarner Morse TEC. "We are pleased to introduce it on Ford's Duratec engine."

Unlike traditional cam phasing methods which typically use engine oil pressure to rotate the camshaft, BorgWarner states that its CTA technology captures the existing torsional energy in the valve train to accomplish this event, similar to a hydraulic ratchet. CTA cam phasers operate more quickly and under a wider range of engine speeds and temperatures than traditional oil pressure actuated cam phasers. These factors allow CTA variable cam timing to more efficiently improve fuel economy, increase horsepower and reduce emissions.
