Abstract
Most of car manufacturers and OEM are currently working on air intake improvement in order to reduce emissions and fulfill the always more demanding ecological regulations. Electric actuation is a relevant solution allowing the use of specific actuators able to actuate flap or valves in few milliseconds over their stroke.
A first solution to adapt the air intake is the integration of an air pulse valve before the piston [1]. Another solution is the use of a fully variable intake system performed by the replacement of the camshaft with electrical actuation of the valves (camless engine) [2].
Thanks to our expertise in electro-magnetism, MMT has developed fast actuator designs dedicated to these applications and we will present them in this paper.
