Temperature differences in one cylinder??

[Kitfox43]

Consider just one cylinder in any 4 or 6 cylinder Lyc or Cont.

Approximately what percentage of the cylinder head temperature is generated by the ignition and what percentage is generated by friction and heat transferred from other areas?
How much difference in cyl head temp between both plugs firing and just one plug firing?

Nearly all of it comes from the combustion in the cylinder in an aircraft engine.

Maybe....maybe not. Corrosion problems can cause cht problems.
