thanks for the video! It's basicly the same design. In my opinion the pistons assamblies are too heavy and complex to compete with other designs like the OPOC. Same problem with the PatOP engine.
Besides the conrod alignement, reducing friction is a great thing, but at the cost of greater piston weight, just like a crosshead.
This type of engine may be able to run, however huge amount of mechanical stress (and loss) will be put on the con rod joint on the plates below the piston as well as those plates. Moreover, piston movement will become a lot heavier and sluggish, whereas its supposed to be as light and easy moving as possible.. Also, the two flywheels will need to be combined. Otherwise, nice design..
I guess the forces on the conrod joints will try to turn it in its cylinder. More joints make more friction. Heavy crankshaft make bad acceleration. Maybe its only suitable for a range xtender application.
I abandonned the design, because it has no great advantages over the PatOP Engine.
Is this a modification of the Doxford marine engine?

Take a look at opposed piston engine low friction.

Using four crankshafts would solve this ;)

I was already influenced by that design, and i'm in contact with the builder for over two years now.
