Engines repeatedly catching fire:

I always wondered if this is a bug or a feature.
When an engine gets damaged to a certain degree it will catch fire no matter what you do.
If you to cut the fuel(0%throttle) and manage blow the fire out and cool the engine down - how can this thing light up again and again?
I mean, there's neither fuel nor any hot parts like the exhaust.
