EMVA

基本解释

Electromechanical valve actuator system (EMVA) uses solenoid to drive each valve independently for achieving variable valve timing (VVT).
电磁式汽门机构使用电磁螺线管式驱动汽门，免除凸轮轴，各汽门可独立控制。
The main issues of the present research (EMVA) aims to the lower power source needed and hybrid magneto-motive force (MMF) usage.
本文的研究主题为利用高磁能积永磁与线圈激磁之混合磁动势，结合低电功率之概念，开发出新型电磁式汽门机构来达到性能需求。
