- Summary:
- The paper gives a short outline of experiences gained at IM inthe design of an electromechanical valve actuator having twomagnets and two balanced springs. This device works at fixed lift,fixed lifting time and variable valve event. Some of most relevanttopics regarding the design of such a type of actuator have beenanalyzed. In particular, in the first part of the paper theproblems of varying load have been tackled with the aid of acommercial one-dimensional code.Based on these results, the electromechanical design of theactuator has been started. Three axial-symmetric geometries havebeen compared using an electromagnetic CAD.The requirements of systems to perform the first lift at enginestart up and the catching in operation have been analyzed. Theevaluation of energy losses connected with these phases has beenalso done
