Variable Camshaft Timing

TiVCT (twin independent variable camshaft timing) is used on this engine.

Continuous adjustment of the valve timings allows the following to be achieved: 

• Smoother idling
• Increase in power and torque
• Sufficient internal exhaust gas recirculation
• Performance optimization at wide open throttle

There is a VCT unit on each camshaft for making the adjustment. The valve timings can be controlled by making engine speed and load dependent adjustments of the intake and exhaust camshafts.
