engine fuel system

engine fuel system

engine fuel systemThat part of the aircraft's overall fuel system that starts after the entry of fuel into the engine. For fuel-injected and turbine engines, a high-pressure (HP) pump takes fuel from the low-pressure, or aircraft, fuel system and raises its pressure sufficiently to ensure an efficient injector or burner operation. It consists of an HP fuel pump and the fuel control unit that determines the quantity of fuel going into the engine, a system of combustion, and an afterburner system, if any. Also known as a high-pressure fuel system.
