Reference Design and Experimental Evaluation of An Electromechanical Engine Valve Drive Y.H.Qiu 2004 35th Annual IEEE Power Electronics Specialists Conference

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

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

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
