4 strokes of the combustion cycle in a single crankshaft revolution

[nova_robotics]

It's neat, but I don't see the benefit. It's like an approximation of the Atkinson cycle with full stroke expansion and a reduced volume intake stroke, but with tons more parts and with a really unreliable looking engagement/disengagement of the two pistons. Also tons more rotating mass. And lots of weird new harmonic balancing issues. Why do this over Atkinson?
