Gas Engines With Fully Digital Valves

Now that we are apparently heading toward an electric vehicle future, here's interesting news about a breakthough in the internal combustion engine. Specifically, the complete digital control of the valves - no rods or actuators, just computer control of each individual valve using a precision electric motor.

Why? Although the internal combustion engine may be "marked for death" it will be around for a while yet, and hybrid electrics need efficient gas engines to pair with the electric system.

This digital valve setup can perform all kinds of tricks that increase efficiency and decrease emissions, so it sounds like something that may really be embraced in the coming years. The article below goes into quite a bit of depth, and is pretty eye-opening as to the possibilities of this technology.
