Great detailed explanations!
If I simplify things, the throttle on a steam engine
controls Torque. To set a certain speed with a
certain load, a certain torque is needed. The
speed regulator (governor) is a device that controls the
applied torque so that the speed remains constant
with varying loads.
I believe a 2-cycle engine (otto or diesel) can be reversed
by simply changing the spark or injection timing, unless
they have some type of rotary intake valving. 4-cycle
engines must have the valve timing reversed, with a different
camshaft (and a few details like oil pump and distributor
gearing). Some modern engines with belt-driven camshafts
have a belt path and hydraulic tightener that probably
would not work properly in the reverse direction.
Interesting stuff!

| (...) Sorry Larry, not true. The throttle controls the pressure in the steam chest (Ideally), which controls the speed. (in fact, it does regulate pressure, but also regulates volume) What you are suggesting is done on some engines (corliss mill (...) (25 years ago, 29-Oct-99, to lugnet.off-topic.geek, lugnet.trains)
