When fuel is added to the exhaust (burnt) gases in a jet engine combustion takes
When fuel is added to the exhaust (burnt) gases in a jet engine combustion takes place. Some facts are mentioned here about this combustion. Pick the false one?
- A. It increases the intake of oxygen from the air
- B. It reduces fuel consumption
- C. It gives additional thrust
- D. It is known as 'after burning'
Step-by-step solution
Afterburning involves injecting fuel into the exhaust stream and igniting it to produce additional thrust. This process increases fuel consumption, not reduces it. Therefore, option B is false. Options A, C, and D are true: afterburning does not increase oxygen intake (it uses leftover oxygen), it provides additional thrust, and it is known as afterburning.
