Question 1: What is the main purpose of an engine?

• To convert fuel into energy
• To generate electricity
• To pump air
• To cool the car

A. To convert fuel into energy

Question 2: What are the four main parts of an engine?

• Cylinder, piston, crankshaft, camshaft
• Cylinder, spark plug, valve, piston
• Cylinder, head, block, oil pan
• Cylinder, crankshaft, camshaft, oil pump

A. Cylinder, piston, crankshaft, camshaft

Question 3: What is the difference between a two-stroke and a four-stroke engine?

• Two-stroke engines have two pistons per cylinder, while four-stroke engines have one piston per cylinder
• Two-stroke engines complete one cycle in two strokes, while four-stroke engines complete one cycle in four strokes
• Two-stroke engines are more powerful than four-stroke engines
• Two-stroke engines are more fuel-efficient than four-stroke engines

B. Two-stroke engines complete one cycle in two strokes, while four-stroke engines complete one cycle in four strokes

Question 4: What is the function of a piston?

• To compress the air-fuel mixture
• To create a vacuum in the cylinder
• To open and close the valves
• To lubricate the engine

A. To compress the air-fuel mixture

Question 5: What is the function of a crankshaft?

• To convert the reciprocating motion of the piston into rotary motion
• To open and close the valves
• To pump oil through the engine
• To cool the engine

A. To convert the reciprocating motion of the piston into rotary motion

Question 6: What is the function of a camshaft?

• To open and close the valves
• To convert the rotary motion of the crankshaft into reciprocating motion of the piston
• To pump oil through the engine
• To cool the engine

A. To open and close the valves

Question 7: What is the difference between a naturally aspirated engine and a turbocharged engine?

• Naturally aspirated engines use only the air that is drawn into the cylinders by the pistons, while turbocharged engines use a turbocharger to force more air into the cylinders
• Naturally aspirated engines are more powerful than turbocharged engines
• Naturally aspirated engines are more fuel-efficient than turbocharged engines
• Naturally aspirated engines are quieter than turbocharged engines

A. Naturally aspirated engines use only the air that is drawn into the cylinders by the pistons, while turbocharged engines use a turbocharger to force more air into the cylinders

Question 8: What is the difference between a gasoline engine and a diesel engine?

• Gasoline engines use spark plugs to ignite the air-fuel mixture, while diesel engines use compression to ignite the air-fuel mixture
• Gasoline engines are more powerful than diesel engines
• Gasoline engines are more fuel-efficient than diesel engines
• Gasoline engines are quieter than diesel engines
