Hi Paul,
I have seen this remark a number of times.

To me, this is analogous to a piston moving up the cylinder, ie
carrying the combustion chamber to the spark plugs which are fixed in
the head; then, after ignition, moving back down the cylinder.

What is the significance of this rarely mentioned fact?

Well for one thing the center of the combustion process
moves side ways away from the plugs instead of just
getting further away. The flame front also moves in the same
direction. It takes a finite amount of time for the flame
front to reach the outer limits of the fuel air mixture. The
flame front does not travel upstream so to speak either.

Soon the spark plugs are completely shut out by the apex seals.
The other thing that is happening is the combustion process is
continually being exposed to new, relatively cool metal in the
rotor housing.

Paul Lamar ...No rotor no motor.

Has anyone experimented with multiple sparks for a single power cycle ?

That is the same plug emits several sparks ?
