Aviation Reciprocating Engines

What are the main components of an aviation reciprocating engine?

• Cylinders, pistons, crankshaft, connecting rods, valves, spark plugs, camshaft

• Gearbox, radiator, exhaust pipe

• Turbine, propeller, fuel injector

• Wings, landing gear, tail fin

Explain the function of the crankshaft in a reciprocating engine.

• The crankshaft adjusts the exhaust system in a reciprocating engine.

• The crankshaft converts linear motion into rotational motion in a reciprocating engine.

• The crankshaft regulates the air intake in a reciprocating engine.

• The crankshaft controls the fuel injection in a reciprocating engine.

What is the purpose of the camshaft in an aviation reciprocating engine?

• To regulate fuel injection

• To adjust the spark timing

• To balance the engine

• To control the opening and closing of intake and exhaust valves at the correct timing.

Describe the role of the pistons in the engine.

• Pistons in the engine control the radio volume.

• Pistons in the engine are responsible for steering the vehicle.

• Pistons in the engine convert pressure from fuel combustion into mechanical energy.

• Pistons in the engine regulate the air conditioning system.

What is the function of the connecting rods in a reciprocating engine?

• Convert linear motion of the piston into rotational motion of the crankshaft

• Adjust valve clearance

• Regulate air intake pressure

• Control fuel injection timing

Explain the importance of the cylinder head in an aviation reciprocating engine.

• The cylinder head is important in an aviation reciprocating engine because it houses critical components like valves, spark plugs, and fuel injectors, seals the combustion chamber, and helps regulate engine temperature.

• The cylinder head is responsible for playing music in the cockpit

• The cylinder head is used to store snacks for the pilot during long flights

• The cylinder head in an aviation reciprocating engine is purely decorative

What are the different types of valves used in reciprocating engines?

• Intake valves and exhaust valves

• Inlet valves and outlet valves

• Inflow valves and outflow valves

• Compression valves and release valves

Describe the function of the intake manifold in an aviation reciprocating engine.

• Regulates fuel flow to the engine

• Controls the landing gear

• Cools the engine cylinders

• Distributes air-fuel mixture to the cylinders

What role does the exhaust system play in the operation of a reciprocating engine?

• The exhaust system increases fuel efficiency by recirculating exhaust gases back into the engine.

• The exhaust system enhances engine power by compressing air before it enters the combustion chamber.

• The exhaust system regulates the temperature of the engine by controlling the flow of coolant.

• The exhaust system expels burned gases from the combustion chamber, maintaining proper engine performance.

How does the lubrication system contribute to the performance of a reciprocating engine?

• Increasing friction and wear

• Causing overheating and inefficiency

• Disrupting smooth operation

• The lubrication system contributes to the performance of a reciprocating engine by reducing friction, minimizing wear and tear, improving efficiency, preventing overheating, and ensuring smooth operation.
