摘要

近年来，人们要求进一步提高内燃机的性能，以减轻环境负担。发动机的燃烧状态受到动态气门系统参数的影响，例如开/关时间和进排气气门的升程。因此，我们研究了一种电磁阀驱动系统。建立了两种模型来改善磁路和增加推力。为了研究这些作动器的推力特性，采用有限元法进行了电磁场分析。同时，为了研究磁轭材料对推力的影响，对不同饱和磁通密度和磁导率的材料进行了电磁场分析。

Basic study on high precision positioning in electromagnetic valve drive system for improving internal combustion engine using linear actuator

In recent years, further improvements in the performance of internal combustion engines to reduce environmental burden have been demanded. The combustion state of an engine is affected by the parameters of the dynamic valve system, such as the opening/closing timing and the lift of the intake and exhaust valves. Therefore, we investigate an electromagnetic valve-drive system in this study. Two models are created to improve the magnetic circuit and increase thrust. To investigate the thrust characteristics of these actuators, an electromagnetic field analysis is conducted using the finite element method. Meanwhile, to investigate the effect of the yoke material on the thrust, an electromagnetic field analysis is performed based on materials with different saturation magnetic flux densities and magnetic permeabilities.
