Maybe this has been posted before. If so, I apologize in advance.
I just read an interesting article about a new style of valve actuation for internal combustion engines. Here is the link:
Intelligent Valve Actuation
A British company has developed a technology that decouples the actuation of intake and exhaust valves from the crankshaft. Each valve is actuated independently. This allows for greater exploration of fuel efficiency techniques such as VVT, etc. Significant efficiency increases are expected. More interestingly, it would allow for short duration of 2 stroke operation (and increased power) from a four cycle engine. Conversely, 12 stroke operation would mimic cylinder deactivation under low load situations, but the dead cylinder can be switched randomly between any of the engines cylinders. The options for independent engine tuners would seem to be greatly increased as well.
It won't be cheap, but new technology never is. Prices will eventually come down.
Looks promising to me.
