What is a multi air engine?

Guys, I am really in a dilemma to what is a multi air engine. Searched on the internet but couldn't get a clear idea of what it is. Please tell if someone knows so. Posted in: #Coffee Room

From what I read, it is a mechanical-electro-hydraulic intake valve actuation technology pioneered by Fiat in 2002 (Source Wikipedia). The intake valve is still cam driven, but controlling the cam is a electro-hydraulic system. It says it betters the power output of the engine and also optimizes gas (petrol) consumption.

The next step is completely camless (pneumatic-electrical) valve control system. At the moment such system is very expensive and I don't think it is about to be introduced in any production engine soon. But that's the future.

Well, thanks for the info.
