System Operation: Ti-VCT
WARNING: This page is about a different car, the 2013 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
TheTi-VCT system allows variable control of intake valve closing which optimizes combustion at full load providing improved power and low speed torque (broadening the torque curve) which enables variable valve overlap which provides better fuel economy and emissions and provides optimized cold start operation with improved exhaust emissions.
