En tout cas faudra que tu penses à corriger wikipedia :

http://en.wikipedia.org/wiki/Deflagration :
Typical examples of deflagrations are combustion of a gas-air mixture in a gas stove or a fuel-air mixture in an internal combustion engine, a rapid burning of a gunpowder in a firearm or pyrotechnic mixtures in fireworks.

http://en.wikipedia.org/wiki/Detonation :
In diesel engines, low sensitivity to these conditions results in ignition being delayed while a highly detonable mixture accumulates, causing detonation when ignition finally occurs.
