During the intake stroke, ________________________________.

• Spent gases are forced out of the combustion chamber from the piston's travel from BDC to TDC

• Fuel is supplied to the combustion chamber

• Air - fuel mixture is deposited into the combustion chamber

• The piston travels from BDC to TDC to compress the fuel charge prior to ignition

Ignition of the charge occurs in between the following two strokes: _________________ and _________________.

• Intake, Power,

• Compression, Power

• Power, Exhaust

• Intake, Compression

Compression is a key element of an internal combustion engine. Which engine component supplies the compression needed to power an engine?

• Crankshaft

• Ignition Armature

• Connecting Rod

• Piston

What position are the valves in during the intake stroke

• Intake Closed, Exhaust Closed

• Intake Open, Exhaust Closed

• Intake Open, Exhaust Open

• I have no idea

What is the primary function of the intake stroke in an internal combustion engine?

• To expel exhaust gases

• To compress the air-fuel mixture

• To draw in the air-fuel mixture

• To ignite the air-fuel mixture

During which stroke does the piston move from TDC (Top Dead Center) to BDC (Bottom Dead Center) while the intake valve is open?

• Intake stroke

• Compression stroke

• Power stroke

• Exhaust stroke

What component in an internal combustion engine is responsible for igniting the air-fuel mixture?

• Piston

• Spark plug

• Crankshaft

• Camshaft

Which of the following best describes the role of the camshaft in an internal combustion engine?

• To convert linear motion to rotational motion

• To open and close the engine's valves

• To ignite the air-fuel mixture

• To supply fuel to the engine

What happens during the compression stroke of a four-stroke engine?

• The air-fuel mixture is ignited

• The air-fuel mixture is compressed

• Exhaust gases are expelled

• The piston moves to BDC
