Twin Independent Variable Camshaft Timing (Ti-VCT) is the name given by Ford to engines with the ability to vary the camshaft timing of both the intake and exhaust camshafts independently. Despite the name difference, its operation is the same as standard VCT. Unlike the original versions of VCT, which only operated on a single camshaft, Ti-VCT allows the PCM to advance or retard the timing of both the intake and exhaust camshafts independently. This allows for improved power and torque, particularly at lower engine RPM, as well as improved fuel economy and reduced emissions.
Many new Ford engines feature Ti-VCT, including the 2011-2013 Mustang, 2011 Edge and Edge Sport, 2011 Lincoln MKX, 2011 Fiesta, 2011 Explorer, and 2012 Focus.
