Either 2 or 4 stroke engines will have the axis of the crankshaft
displaced to accommodate more efficient coupling during the power
stroke. Can only run in one direction ...

Actually, I have seen large marine Diesel engines which could run in
either direction. They were brought to a complete stop, the intake and
exhaust were switched, then the engines were restarted going the other
direction. You design engines correctly, that's possible.

Your exception doesn't really break the rule. There are several design
features of normal engines optimized for rotation in only one
direction. eg - intake vs. exhaust : valves, ports, open/close
positions, etc. ..., connecting rod bearings, ...

My mistake - NOT the connecting rod bearings.
