Piston Engine Quiz

What is the primary function of a piston in a piston engine?

• Compress air-fuel mixture

• Rotate the crankshaft

• Create a vacuum

• Control the exhaust gases

In a four-stroke piston engine, what happens during the power stroke?

• The piston compresses the air-fuel mixture

• The fuel is ignited and the piston is forced down

• The exhaust valve opens

• The intake valve opens

What component links the piston to the crankshaft in a piston engine?

• Camshaft

• Connecting rod

• Flywheel

• Cylinder

Which component in a piston engine is responsible for regulating the entry of air-fuel mixture into the combustion chamber?

• Crankshaft

• Intake valve

• Exhaust valve

• Piston rings

Which of the following is a characteristic of the compression stroke in a four-stroke piston engine?

• The intake valve opens

• The piston moves upward

• The spark plug fires

• The exhaust valve is open

During which stroke of a four-stroke engine is the fuel-air mixture ignited?

• Intake

• Compression

• Power

• Exhaust

What is the purpose of the spark plug in a piston engine?

• Compress the fuel-air mixture

• Ignite the compressed fuel-air mixture

• Open the intake valve

• Regulate the fuel flow

In a piston engine, the exhaust valve opens during which stroke?

• Intake

• Compression

• Power

• Exhaust

Which of the following best describes the role of the crankshaft in a piston engine?

• It compresses the air-fuel mixture

• It transforms the reciprocating motion of the piston into rotary motion

• It controls the timing of the valve operation

• It ignites the fuel-air mixture

In a piston engine, what happens during the intake stroke?

• The air-fuel mixture is ignited

• The piston moves up, compressing the air-fuel mixture

• The air-fuel mixture enters the cylinder

• The exhaust gases are expelled
