Engine Control System Components

Tabel 1.1

Engine System	Purpose
Lubrication System	Supply lubrication and cooling oil to the main engine bearings and accessory drives
Fuel System	To supply fuel at the proper pressures and flow rates to support combustion
Bleed System	To permit operational flexibility by minimizing the possibility of compressor stall when the compressor system is operating at off-design speeds
Ignition System	To provide a high intensity spark for ignition of the fuel under all operating conditions
Anti-Icing System	Prevent icing of the fan inlet case and guidevane assemblies
Engine Indicating Systems	Sensing exhaust gas temperature and total turbine discharge pressure
