That engine is pretty clever, using manual rods from the crank to open and close ports.

So the piston is connected to one or both of the valves? If you made the valves come off the piston at 90 degress then you could have one cylinder with two expansion strokes as you could have a combustion area on either side of the piston.

Look at it again, there are no valves, only ports. There are already two combustion chambers per cylinder. The rods you see are the scotch yoke/connecting rod for the piston. Actually though if I had them go 90 degrees and then down I wouldn't have the difference in exhast flow on the bottom chambers.
