Preliminary experiences in the design of an electromechanical valve actuator 2001-24-0016
The paper gives a short outline of experiences gained at IM in
the design of an electromechanical valve actuator having two
magnets and two balanced springs. This device works at fixed lift,
fixed lifting time and variable valve event. Some of most relevant
topics regarding the design of such a type of actuator have been
analyzed. In particular, in the first part of the paper the
problems of varying load have been tackled with the aid of a
commercial one-dimensional code.
Based on these results, the electromechanical design of the
actuator has been started. Three axial-symmetric geometries have
been compared using an electromagnetic CAD.
The requirements of systems to perform the first lift at engine
start up and the catching in operation have been analyzed. The
evaluation of energy losses connected with these phases has been
also done.
