PASGT Quiz 3

What is the primary function of the lubrication system?

• To store excess oil.

• To reduce friction between moving parts.

• To increase engine temperature.

• To filter contaminants from the fuel.

Name two components of the lubrication system.

• oil pump, oil filter

• fuel injector

• radiator cap

• spark plug

How does the lubrication system help in cooling?

• The lubrication system cools the engine by reducing friction between moving parts.

• The lubrication system helps in cooling by circulating oil that absorbs and carries away heat from engine components.

• The lubrication system prevents overheating by using air instead of oil.

• The lubrication system cools by spraying water on engine parts.

What role does the oil filter play in the lubrication system?

• The oil filter increases oil pressure in the system.

• The oil filter regulates the temperature of the engine oil.

• The oil filter cleans the engine oil by removing contaminants.

• The oil filter adds additives to the engine oil.

What is the purpose of the fuel system in a gas turbine?

• To provide electrical power to the turbine.

• To supply and manage fuel for combustion in the gas turbine.

• To filter air entering the combustion chamber.

• To cool the gas turbine components.

How does the fuel control unit regulate fuel flow?

• The fuel control unit adjusts the fuel metering valve to regulate fuel flow based on engine demands.

• The fuel control unit relies on ambient temperature to determine fuel flow.

• The fuel control unit uses a mechanical pump to increase fuel pressure.

• The fuel control unit directly injects fuel into the combustion chamber.

What is the significance of filtering contaminants from the fuel?

• It enhances the smell of the exhaust fumes.

• It has no impact on engine performance.

• It prevents engine damage and improves efficiency.

• It increases fuel consumption and reduces power.

What is the main function of the starting system?

• To initiate the engine's operation.

• To cool the engine during operation.

• To increase fuel efficiency.

• To enhance the vehicle's audio system.

How does the starter motor contribute to the gas turbine operation?

• The starter motor cools the gas turbine during operation.

• The starter motor regulates fuel flow to the gas turbine.

• The starter motor provides electrical power to the gas turbine's control system.

• The starter motor initiates the rotation of the gas turbine's rotor for starting operation.

What is the relationship between engine load and fuel delivery?

• Fuel delivery is constant regardless of engine load.

• Higher engine load decreases fuel delivery.

• Engine load has no effect on fuel delivery.

• Higher engine load results in increased fuel delivery.
