This is much more promising than the other engine designs that try to maximize torque by increasing mechanical advantage of the crank.
This design made the rounds while I was in college.

Funny thing, college taught me about thermodynamics and what goes on in the cylinder doesn't really care about what goes on under the cylinder. Expansion ratio determines everything.

I still have doubts about how significant this will be, and I still have reservations about the effect of piston-porting on emissions due to engine oil unavoidably getting involved in the combustion process.

Regrettably, I failed to mention my favorite OP engines: the Napier Deltic and the Doxford marine engine.

Here is a pretty interesting YouTube on the Deltic if anyone interested, https://www.youtube.com/watch?v=-vV-YaKsIGk
