Propulsion - Engine Fuel Systems

What is used to provide a supply of fuel to the engine at a suitable pressure , rate of flow and temperature?

• Low pressure

• High pressure system

• Low pressure shut off valve

How is the High Pressure fuel pump protected from particle contamination?

• Low pressure fuel filter

• Low pressure shut of valve

• Low pressure fuel pump

What maintains pressure on the fuel in the line to the engine driven pump to prevent vapour lock forming in these lines?

• Fuel boost pump

• Solenoid operated valve

• Fuel cooled oil cooler

What is the advantage solenoid operated valve has over motor driven gate valve in a low pressure system?

• Speed

• Effectiveness

• Maintenance accessibly

What is used to cool the hot engine lubricating oil by passing fuel flowing to the engine through a heat exchanger

• Fuel Cooled Oil Cooler

• Low pressure shut off valve

• Fuel heater

Apart from what the particular use a Fuel Cooled Oil Cooler and Fuel Heater serve, what is the other major difference?

• FCOC uses bypass valve, Heater uses temp sensing oil or air shut off valve to control fuel temps.

• FCOC uses a temp sensing oil or air shut off valve to control fuel temps and Heater uses a bypass valve

Spur gear pump is considered to be?

• Continuous fuel injection

• Variable fuel injection

• Minimal fuel injection

What determine the stroke of the plungers in a multiple piston pump?

• Angle of inclination on the camplate

• Pressure provided by the spring

• The change in fuel displacement in the system

What does the high fuel pump filter provide for the FCU?

• Particle contamination

• Structural assistance

• Variable view input

What does the Fuel Control Unit prevent the engine from doing?

• Over fuel absorption

• Fuel contamination

• Exceeding max limitations
