High Speed Electric Actuator Designs for Improved Air Intake

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.
