turbofan vs. turbojet

turbofan vs. turbojet: 's the difference?

A turbofan is a more advanced type of turbojet engine. A turbojet sucks in air and compresses it, creating combustion of fuel. A turbofan has a large fan that sucks in a lot of air, but only part of it is used to fuel the engine’s combustion, the rest exiting as exhaust. This makes it less noisy and more powerful.
