This assumes that the materials can handle the forces and adiabatic expansion.
Look up the later to see why HHO works.

Nothing to do with materials withstanding forces! look at the geometry - pushing down on the piston when the crank is at full extension and the connecting rod is aligned with it will waste a f$%^load of energy trying to compress the connecting rod as well as squeezing out the oil film and destroying the bearings. It will also try to push the piston out the side of the cylinder bore.
Seriously, time would be better spent discussing the benefits of building engines from unobtanium and running them with dilithium crystal powered warp generators.
