“…It improves fuel efficiency by up to 15%, enhances torque output by up to 10% and reduces CO 2 emission by up to 15% under different engine operating conditions [1,2]. The solenoid-driven electromagnetic engine valve actuator is the most advanced system among the devices that had been developed in the past several years to replace the traditional mechanically driven camshaft engine valve system [3,4].…”

Abstract:In this research, the design of a new electromagnetic engine valve in the limited space of combustion engine is optimized by multidisciplinary simulation using MATLAB and Maxwell. An electromagnetic engine valve actuator using a permanent magnet is a new actuator concept for overcoming the inherent drawbacks of the conventional solenoid-driven electromagnetic engine valve actuator, such as high power consumption and so on. This study aims to maximize the vibration frequency of the armature to reduce the transition time of the engine valve. The higher performance of the new actuator is demonstrated by dynamic finite element analysis.

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).
