Engine Review Quiz

This part makes up the main body of the engine. It contains the cylinders, pistons, connecting rods and crankshafts.

• Cylinder Head

• Engine Block

• Valve Train

• Unibody

Which engine stroke does this describe?

Both valves are closed. The spark plug ignites as the piston reaches the top of the cylinder, causing a forceful burning of the air-fuel mixture. This rapid burning forces the piston downwards and causes the crankshaft to rotate.

• Intake Stroke

• Compression Stroke

• Power Stroke

• Exhaust Stroke

The timing belt/chain connects the camshaft to the:

• Valves

• Pistons

• Flywheel

• Crankshaft

What are installed in engine pistons in order to help seal the chamber?

• Pins

• Grooves

• Rings

• Skirts

True or False?

The crankshaft controls the opening and closing of the engine's valves.

• True

• False

Which engine stroke does this describe?

Both valves are closed, sealing the chamber. The air-fuel mixture is combined further together as the piston moves upwards.

• Intake Stroke

• Compression Stroke

• Power Stroke

• Exhaust Stroke

This part of the engine sits on the top. It contains the valve train.

• Camshaft

• Cylinder Head

• Engine Block

• Timing Belt

The _ connects the crankshaft to the piston.

• Camshaft

• Timing Belt

• Valve

• Connecting Rod

In a standard engine, the reciprocating (up and down) motion of the pistons is changed into rotational motion by the:

• Bearings

• Crankshaft

• Flywheel

• Wrist Pin

True or False?

The valves are held shut by a very strong spring.

• True

• False
