th Annual IEEE Power Electronics
Specialists Conference

3. Objectives To design a feedback engine valve timing control system
To design a PID controller
To design circuit for each block of the system
To evaluate the performance of the new design EMEVD system using Matlab simulation tools

4. Abstract
Valve timing control of conventional internal combustion (IC) engine
New electromechanical engine valve drive (EMEVD)
Improve the fuel efficiency and engine performance

5. Conventional IC Valve Timing
Valves timing is governed by a belt- or chain-driven camshaft
Camshaft shape is determined by considering tradeoffs between engine efficiency, torque requirement and maximum power
