- combustion in an afterburner that results from the injection of fuel into the exhaust gases of a jet engine to produce additional thrust with more efficient fuel consumption.
- an irregular burning of residual fuel in some rocket motors after the cessation of the main burning.
- a process in which additional fuel is ignited in the exhaust gases of a jet engine to produce additional thrust
- irregular burning of fuel in a rocket motor after the main burning has ceased
- persistence of combustion in an internal-combustion engine, either in an incorrect part of the cycle or after the ignition has been switched off
