Forced induction works really well on 2 strokes as it really helps cram the air in during the brief period of time the intake ports are open.

Glancing at that drawing, my guess is that the motor has variable base compression ratio built into that gizmo on the backside of the outer pistons. By using a opposed piston design, you gain variable base compression on all 4 pistons with half as many rod length adjuster (or whatever they should be called). If that gizmo is complicated/expensive/heavy it may be a benefit to go with a non-traditional 1 piston per cylinder.
Variable base compression would allow an additional layer of dynamic optimization of efficient vs. power, plus the ability to run a huge range of fuels... or even a mixture of fuels... imagine topping off a tank of diesel with gasoline and having the motor sort out the ideal compression ratio on the fly as the fuels mix. :lol:
Then again, I'm just looking at that drawing... I didn't read the website.
