It would be neat to have the Glow plug, but also have a contra piston (like some model diesels have) to vary the compression ratio while a Gas/Glow engine is running. Can it be done? Capt,n[:-]
Yes, I'm in the middle of doing that now.
Another thought. Way back before glow, purpose built ignition engines as in O&R and the like had a very small spark plug not unlike glow plugs of today. What if the heads on our conversions used that sort of spark plug? Increased efficiencies due to smaller threads exposed to the combustion chamber? We may find out.
