Piston spark ignition points?
Roger B:
All the succesful opposed piston engines I am aware of have been two stroke diesesl (generally following Junkers). There were a couple of early 4 stroke gas/petroleum engines, one of which used hot tube ignition (Saurer).
How about a Piezo ignition module in the crown of the, hopefully cooler, inlet piston operated by a push rod from the exhaust piston approaching TDC.

I honestly don't remember who made the Piston as part for the Plug (so to speak) - but SAAB is a good bet - they where rather inventive ....
I can't see an Ignition system integrated into the Piston being a reliable option - all those vibrations have a very negative effect ....
I don't see Rogers option having a variable Timing option ....

Quite some Fairbanks Morse OP engines are or have been sold for natural gas with spark ignition methinks.
Piezzoes are in consideration.

This company, Enginuity Power Systems, seems to be some way along the CHP path with an opposed piston 4 stroke. Here is a diagram of their system and a couple of links. As it is a 4 stroke there seems to be space for a conventional spark plug.

I have been following this thread and I may be confused but this is a 2 piston, 2 crankshaft, opposed model I built a while back.

I may have completely misunderstood so just disregard if I did.
