Engine Control Systems I - Course 852 8-5. Variable Valve Timing & Acoustic Control Induction Systems. This VVT-i controller comprises of an outer gear driven by the timing. belt, an inner gear affixed to the camshaft, and a movable piston that is. placed between the outer gear and inner gear.
In internal combustion engines, variable valve timing is the process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems. There are many ways in which this can be achieved, ranging from mechanical devices to electro-hydraulic and camless systems. Increasingly strict emissions regulations are causing many automotive manufacturers to use VVT systems. Two-stro
