its not a mystery that 2 stroke motors are monsters. they always have been. the only bad thing about them was that they dont use fuel efficiently and burn much more oil than a 4 stroke engine. they also produce more pollution. now, if this engine solves these problems, then you can bet that this is the next big thing.
i would LOOOOOVE to see some 2 stroke engines get put to use in something more than a chainsaw or a lawnmower. lol
2 cylinders 4 pistons, intresting. too bad its extremely impractical because the outer connecting rod is limited on thickness they have to be made of exotic metals, titanium in this case
and actually the more i look at it the LESS efficient it appears to be. Because of its dual piston design it makes for very inefficient removal of exhaust gases.

Titanium connecting rods aren't too hard to come by nowadays, even for common commercial use, titanium is a lot more ubiquitous than it used to be.
Normal 2-stroke engines (ie. lawnmowers, dirtbikes, snowblowers, etc) use an oil and gas mixture due to packaging constraints. The symplified design allows for a smaller and less complex engine, which is vital for these applications.
When you're talking about an engine this size, this is not such a factor, and it's possible that it has a lubrication system much like we're used to on our 4-cycle cars. If this is the case, then it would have better emissions than your average 2-cycle engine. Of course this is just speculation, and we'd have to see more specifications before we can be sure either way.
It will be interesting to see if some of these designs make it into production for mass-consumption applications, and also what the emissions are like on these engines.
