6 sub-systems of an Engine Flashcards
Name 6 sub-systems of an Aircraft Piston Engine?
- Ignition-Start System.
- Induction and Carburettor System.
- Fuel System.
- Lubrication System.
- Exhaust System.
- Cooling System.
What’s the purpose of an Ignition-Start System?
- To start turning the engine by the starter motor.
- To provide a high voltage spark to ignite the fuel-air mixture.
What are the major components of an Ignition-Start System?
- Ignition-Starter Switch.
- Battery and Starter motor.
- Magnetos.
- Spark Plug.
What is the Pilot’s job for Ignition-Start System?
To check and monitor the proper operation of the dual magnetos before and during flight.
What’s the purpose of an Induction and Carburettor System?
- To duct and condition the air drawn in to the Fuel Control unit then to individual Cylinders.
- To mix the fuel with the incoming air to the CCM ratio.
What are the major components of an Induction and Carburettor System?
- Air Filter.
- Duct and Manifolds.
- Fuel Control unit (Carburettor/Injection System).
- Throttle Valve.
- Mixture Control mechanism.
What is the Pilot’s job for Induction and Carburettor System?
- To check the Carburettor Heat is operational before flight.
- To control engine power by the throttle.
- To adjust air-fuel mixture ratio by mixture control.
- To monitor Carburettor Icing and apply heat if necessary.
- To shut down engine using the mixture control (idle-cut-off).
What’s the purpose of a Fuel System?
- To provide for the storage of Fuel.
- To supply an adequate flow of Fuel to the Fuel Control unit.
What are the major components of a Fuel System?
- Fuel Tanks and Vents.
- Fuel Pumps.
- Manual Fuel Primer.
- Fuel Selector and Shut-Off Valves.
What is the Pilot’s job for Fuel System?
- To ensure correct grade of Fuel is being used.
- Always check quantity of Fuel visually.
- Always check for Fuel Contamination before flight.
- To change Fuel Tank appropriately (low-wing Aircraft).
What’s the purpose of a Lubrication System?
- To reduce Friction.
- To aid Engine Cooling.
- To carry away dirt.
What are the major components of a Lubrication System?
- Wet-sump.
- Engine-driven Oil Pump.
- Filter.
- Oil Cooler.
- Temperature Gauge.
- Pressure Gauge.
What is the Pilot’s job for Lubrication System?
- To check Oil level using the dipstick before each flight.
- To monitor Oil Temperature and Pressure during flight.
What’s the purpose of an Exhaust System?
- To release burnt gases – Carbon Dioxide and Monoxide.
- To provide heated air for the Carburettor Heat System and the cabin.
What are the major components of an Exhaust System?
- Muffler/Shrouds.
- Exhaust Risers.
- Tailpipes.
