LESSON # 2 Flashcards
To boost pressure of the fuel to prevent cavitation of the HP pump.
LP FUEL PUMP/ Low Pressure Fuel Pump
To provide means of drawing fuel from the fuel tanks in the event
of failure of the fuel boost pump in the tank.
LP FUEL PUMP/ Low Pressure Fuel Pump
Form the LP Cock, fuel passes to an engine driven LP Fuel Pump which
serves two purposes:
A. To boost pressure of the fuel to prevent cavitation of the HP
pump.
To provide means of drawing fuel from the fuel tanks in the event
of failure of the fuel boost pump in the tank.
LP FUEL PUMP/ Low Pressure Fuel Pump
To reduce the possibility of low temperatures forming ice, fuel heating is applied. Fuel heating is achieved by passing the fuel through a form of radiator which uses hot air (or hot oil) to control and maintain
fuel temperature above freezing.
FUEL/AIR HEAT EXCHANGER
Its purpose is to prevent foreign particles from entering the engine fuel system.
LP FUEL FILTER/ Low Pressure Fuel Filter
Not withstanding this, (?) will be incorporated to ensure that the fuel supply, albeit possibly
contaminated is still available.
