摘要：

This paper focuses on external volume and power consumption optimization of an electromagnetic actuator used to move pins in a two-stage variable valve lift component within an automotive engine. This system is designed to change the valve lift at each engine cycle. To achieve this optimization, three models were developed: a magnetic, an electric, and a dynamic model. They evaluate the performances of a given actuator, check if it fulfills its role, and define the springs needed for the displacement of the pins. The optimization is made using a particle swarm method and can reduce the volume up to 20% with the same electric consumption.
