A Novel of Hybrid Magnet Engine Valve Actuator Using Shorted Turn for Fast Initial Response

Duc Thuan Vu and Hwang Pyung
Abstract—A variable valve timing (VVT) can improve fuel efficiency, reduce CO2 emission and increase torque output. To achieve VVT in internal combustion engine, new devices such as mechanical, hydraulic, motor-driven and electromagnetic actuator have been developed in past years to replace the conventional camshaft valve train system used currently. Among these, the electromagnetic actuator using solenoids is the most advance system to provide the most flexibility to valve timing, but it has critical drawback of high power consumption. This paper presents a novel design of Hybrid Magnet Engine Valve Actuator (HMEVA) using shorted turn. A shorted turn is placed into existing design in order to reduce the inductance of coil and improve the initial response. Dynamic finite element analysis using commercial electromagnetic solver “MAXWEL” is performed to simulate the improvement of dynamic characteristic of model.

Index Terms—Variable valve timing (VVT), hybrid magnet engine valve actuator (HMEVA), shorted turn, finite element analysis, permanent magnet (PM), electromagnet (EM).
