A spark plug is fired at 18° bTDC in an engine running at 1800RPM. It takes 8° of engine rotation to start combustion and get into flame propagation mode. Flame termination occurs at 12° aTDC. Bore diameter is 8.4 cm and the spark plug is offset 8mm from the centerline of the cylinder. The flame front can be approximated as a sphere moving out from the spark plug.
