BorgWarner VCT technology drives Ford super duty trucks

ABR Staff Writer Published 08 February 2011

BorgWarner, a provider of engineered components and systems for vehicle powertrain applications worldwide, said that its cam torque actuated (CTA) variable cam timing (VCT) technology and timing drive system contribute to improved horsepower, increased fuel economy and reduced emissions for the all-new 2011 Ford Super Duty 6.2-liter V8 gasoline engine.

The company said that by optimizing VCT, its CTA technology enables engines to run more efficiently at all engine speeds with faster response than traditional hydraulic oil-actuated VCT systems.

BorgWarner's technology helps these Super Duty trucks provide 385 horsepower, contributes to delivering 405-lb-ft of torque and assists in attaining 15% better fuel economy than the previous 5.4-liter engine.

BorgWarner Morse TEC president and general manager James Verrier said the company's CTA technology and timing drive system help these Ford trucks deliver the powerful performance drivers expect with the added benefits of improved fuel economy and reduced emissions.

"The technology debuted on the 2009 Ford Escape and was launched earlier this year on the 2011 Ford Mustang GT," Verrier said.

"We're pleased that Ford is continuing to use our CTA technology on a growing number of vehicles."

VCT which is designed to maximize fuel economy and performance, optimizes the opening and closing of intake and exhaust valves throughout the engine operating range.

The company said that unlike traditional cam phasing methods, which typically use engine oil pressure to phase the camshaft, its CTA technology utilizes the existing torsional energy in the valve train, similar to a hydraulic ratchet, to phase the camshaft.
