the "duh" answer- it happens when there's fuel in the exhaust with an air/fuel ratio that allows combustion, and an energy source to start said combustion

what Scotty was suggesting (do correct me if I'm wrong) was that if you add fuel on over run (when the engine is spinning down during a shift, or right after you put it into neutral) then there will be no spark in the cylinder, but fuel being injected and air being pumped through the engine, then you rely on the hot exhaust pipe as the ignition energy

other people are suggesting using an alternate fuel injector and spark plug for said fuel and ignition energy, but I'm not sure where they're going to get the air (oxygen) from
