I would assume (yeah, I know assume = ...) that the temperature is rising
throughout the flame front travel, and then drops as pressure drops when the
piston starts significantly accelerating down. The air:fuel mix in front of
the flame front also heats up by radiation from the flame front. I would
think the end gasses behind the front would heat too, and be fairly uniform
across the cylinder (in the area where the flame front is not).
