Correct Answer:

Two revolutions (720 degrees)

Question 2

Valve overlap in a reciprocating engine refers to the period when:

Correct Answer:

Both the intake and exhaust valves are open simultaneously near top dead center

Question 3

What is the primary purpose of the dynamic dampers (counterweights) attached to the crankshaft of a radial reciprocating engine?

To increase the compression ratio To balance the propeller load To reduce torsional vibration of the crankshaft To increase crankshaft RPM

Correct Answer:

To reduce torsional vibration of the crankshaft

Question 4

The compression ratio of a reciprocating engine is defined as the ratio of:

Cylinder bore to piston stroke Power output to fuel consumed Intake manifold pressure to atmospheric pressure Cylinder volume at bottom dead center to cylinder volume at top dead center

Correct Answer:

Cylinder volume at bottom dead center to cylinder volume at top dead center

Question 5

Detonation in a reciprocating engine cylinder is best described as:

An instantaneous, explosive, and uncontrolled burning of the remaining charge The normal progressive burning of the fuel-air mixture Combustion that begins before the spark plug fires A misfire caused by a fouled spark plug

Correct Answer:
