Usually some carbon deposits are left clinging to the combustion chamber surfaces, these deposits are red hot and ignite fuel/air mixture after the ignition is turned off. This could be caused by letting the vehicle idle excessivly long or only using it for short low speed trips. some times it may be caused by too rich of a fuel/air mixture. If it is carburated, if the idle is too fast it will cause it to diesel.
