What is a MultiAir engine and how does it work?

Basically, the multiair engines use electro-mechanical solenoids to open and close the valves for each cylinder. Thereby eliminating the need for an intake “butterfly”, to control the airflow into the engine. The valves can be operated to open to any desired lift as well as change valve timing without the need of a hydraulically variable cam gear.
