That is interesting!
Thats an "opposed piston" engine.
Fairbanks-Morris built a 10 cylinder (thats 20 pistons), diesel engine for World War 2 submarines. No valves, no valve train, no cam shaft, no pushrods, no lifters, etc.
But it does require a scavaging air blower or turbo to make it run.

I got to work on a pair of those engines (FM 38D 8 1/8) in a 4000 horsepower tugboat, on the great lakes. The darn things had aluminum main and rod bearings - indeed an unusual engine.
Its an old idea.
I wonder how they will meet EPA emissions, considering that its a 2 stroke engine?
