    • Camshaft
    • Crankshaft
    • Valve-train

    The air fuel mixture is actually burned during the:

    • Power stroke
    • Intake stroke
    • exhaust stroke
    • compression stroke

    How many crankshaft rotations are needed to complete the four-stroke cycle?

    • one
    • two
    • three
    • four

    • A only
    • B only
    • Both A and B
    • Neither A and B

    Which of the following is not a valve-train component?

    • Camshaft
    • Crankshaft
    • Rocker arms
    • Valve springs

    Which of the following helps prevent crankshaft vibration and damage?

    • Crank damper
    • Vibration damper
    • Harmonic balancer
    • All of the above

    Which of the following is used to turn the camshaft at one-half the speed of the crankshaft?

    • Timing belt
