You get hot spots on the pistons that causes the fuel to ignite before the spark plug intends it too and so you get a double explosion which causes the piston to be pushed in different directions. When the pinging gets bad, thats when the engine pops (or backfires if you prefer).

Not all backfiring is caused by pinging of course though right >
