Questions and Answers
  • 1. 

    What is the largest part of the engine?

    • A.

      Engine Block

    • B.

      Cylinder Head

    • C.

      Compression Chamber

    • D.

      Valve Train

    Correct Answer
    A. Engine Block
    Explanation
    The engine block is the correct answer because it is the largest part of the engine. It is a large metal casting that houses the cylinders, crankshaft, and other internal components of the engine. The engine block provides the foundation for the engine and contains various passageways for coolant, oil, and other fluids to flow through. It is also responsible for providing strength and rigidity to the engine, as well as housing the pistons and connecting rods.

    What is the can shaped part inside the cylinder that moves up and down?

    • A.

      Compression Chamber

    • B.

      Spark Plug

    • C.

      Piston

    • D.

      Exhaust Valve

    Correct Answer
    C. Piston
    Explanation
    The can-shaped part inside the cylinder that moves up and down is called the piston. The piston is a crucial component of an internal combustion engine as it helps in the intake, compression, combustion, and exhaust processes. It moves up and down within the cylinder, driven by the force of expanding gases, and transfers this motion to the crankshaft, which ultimately converts it into rotational motion.

  • 3. 

    What seals onto the engine block and holds the valves?

    • A.

      Cylinder Block

    • B.

      Combustion Chamber

    • C.

      Cylinders

    • D.

      Cylinder Head

    Correct Answer
    D. Cylinder Head
    Explanation
    The cylinder head is the part of the engine that seals onto the engine block and holds the valves. It is responsible for housing the combustion chambers and contains passages for air and fuel intake as well as exhaust gases. The cylinder head plays a crucial role in the overall functioning of the engine by sealing the combustion chambers and allowing for proper airflow and fuel mixture.

    Rate this question:

  • 4. 

    The lobes on this component opens the valves.

    • A.

      Crankshaft

    • B.

      Cylinder

    • C.

      Camshaft

    • D.

      Rocker Arm

    Correct Answer
    C. Camshaft
    Explanation
    The camshaft is responsible for opening and closing the valves in an engine. It has lobes or protrusions that push against the valves, causing them to open. As the camshaft rotates, the lobes come into contact with the valves and lift them, allowing air and fuel to enter the cylinder or exhaust gases to be expelled. The lobes on the camshaft are specifically designed to control the timing and duration of the valve opening and closing, ensuring proper engine performance. Therefore, the camshaft is the correct component that opens the valves.

    This part supplies electricity to charge battery and supplies electricity to vehicle while it is running.

    • A.

      Water Pump

    • B.

      Camshaft

    • C.

      Oil Pan

    • D.

      Alternator

    Correct Answer
    D. Alternator
    Explanation
    The alternator is responsible for supplying electricity to charge the battery and also provides electricity to the vehicle while it is running. It converts mechanical energy into electrical energy, ensuring that the battery remains charged and the electrical systems of the vehicle are powered. This is essential for the proper functioning of the vehicle's electrical components such as lights, radio, and other accessories.

    Rate this question:

  • 6. 

    A: Valve Spring  B: Valve Retainer  C: Valve Keepers

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The given correct answer is "True." However, without any context or question provided, it is impossible to determine the specific explanation for why this answer is true.

    Rate this question:

  • 7. 

    Waste goes from the combustion chamber to the tailpipe through this component.

    • A.

      Intake Manifold

    • B.

      Exhaust Manifold

    • C.

      Distributor

    • D.

      Differential

    Correct Answer
    B. Exhaust Manifold
    Explanation
    The exhaust manifold is responsible for collecting the waste gases produced during combustion in the engine's combustion chamber and directing them towards the tailpipe for release into the atmosphere. It acts as a passage that connects the engine's cylinders to the exhaust system.

    Rate this question:

  • 8. 

    Push Rods and Rocker Arms are needed when the camshaft is ABOVE the valves (not down by the crankshaft).

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Push rods and rocker arms are not needed when the camshaft is above the valves. In an overhead camshaft (OHC) configuration, the camshaft is located above the valves, allowing it to directly actuate the valves without the need for additional components like push rods and rocker arms. In this configuration, the camshaft directly opens and closes the valves, resulting in a more efficient and compact design compared to engines with push rods and rocker arms. Therefore, the statement is false.

    Rate this question:

  • 9. 

    What are these?

    • A.

      Pushrod ~ Rocker Arms

    • B.

      Connecting Rod ~ Rocker Arms

    • C.

      Push Cam ~ Chamshaft

    • D.

      Lifter ~ Lobe

    Correct Answer
    A. Pushrod ~ Rocker Arms
    Explanation
    A pushrod is a component that transfers the motion from the camshaft to the rocker arms. The rocker arms, on the other hand, are responsible for transferring the motion from the pushrod to the valves. Therefore, the pushrod and rocker arms work together in an engine to control the opening and closing of the valves.

  • 10. 

    Takes spark from ignition coil and distributes to spark plugs at proper time.

    • A.

      Differential

    • B.

      Cylinder Block

    • C.

      Distributor

    • D.

      Battery

    Correct Answer
    C. Distributor
    Explanation
    The distributor is responsible for taking the spark from the ignition coil and distributing it to the spark plugs at the correct time. It ensures that each spark plug receives the spark at the precise moment it is needed in the engine's combustion cycle. Without a properly functioning distributor, the engine may misfire or not run at all. Therefore, the distributor is the correct answer in this case.

    What is this picture?

    • A.

      Journal

    • B.

      Crankshaft

    • C.

      Bearing

    Correct Answer
    C. Bearing
  • 12. 

    What is this picture?

    • A.

      Crankshaft

    • B.

      Camshaft

    • C.

      Connecting Rod

    Correct Answer
    A. Crankshaft
    Explanation
    This picture shows a crankshaft. A crankshaft is a mechanical component in an engine that converts the reciprocating motion of the pistons into rotational motion. It is responsible for transmitting power from the engine to the wheels, allowing the vehicle to move. The crankshaft has a series of connecting rods attached to it, which are used to connect the pistons to the crankshaft. The camshaft, on the other hand, is responsible for controlling the opening and closing of the engine's valves.

    What is this picture?

    • A.

      Air Filter

    • B.

      Gas Filter

    • C.

      Oil Filter

    Correct Answer
    C. Oil Filter
    Explanation
    This picture is an oil filter. Oil filters are used in vehicles and machinery to remove contaminants and impurities from the engine oil, ensuring that it remains clean and free of debris. By filtering out particles and preventing them from circulating through the engine, the oil filter helps to protect the engine and maintain its performance and longevity.

  • 14. 

    The oil pan is at the top of the engine block.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The oil pan is not at the top of the engine block. The oil pan is actually located at the bottom of the engine block. It is a reservoir that holds the engine oil and is typically bolted to the bottom of the engine. This allows the oil to be collected and circulated throughout the engine to lubricate its moving parts.

    Rate this question:

  • 15. 

    Intake Valves are BIGGER than Exhaust Valves

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Intake valves are bigger than exhaust valves because they need to allow a larger volume of air-fuel mixture to enter the combustion chamber during the intake stroke. This is necessary for efficient engine operation as a greater amount of air-fuel mixture leads to more power and better combustion. On the other hand, exhaust valves are smaller because they only need to allow the combustion byproducts to exit the engine during the exhaust stroke.
