BorgWarner VCT Technology Powering 2011 Ford 6.2l Super Duty Trucks

BorgWarner is reminding us that its Cam Torque Actuated (CTA) variable cam timing (VCT) technology is one of the developments that allows the all-new 2011 Ford Super Duty 6.2 liter V8 gasoline powerplant to offer a high level of fuel economy and cut emissions.

The tech optimizes variable cam timing, allowing the engine to run with increased efficiency throughout the rpm range, offering it a faster response than traditional hydraulic oil-actuated VCT systems.

CTA helps the Super Duty trucks to offer best-in-class 385 hp, contributes to delivering 405 lb-ft of torque and helps the achieving of a 15 percent better fuel economy (compared to the previous 5.4-liter mill).

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,” stated the press release, explaining how the system works.

The technology made its debut on the 2009 Ford Escape and was also introduced on the 2011 Mustang GT. Ford is expected to expand the list of vehicles that use the technology to maximize efficiency.
