spark plugs review

What is the primary function of a spark plug in an engine?

• To cool the engine

• To ignite the air/fuel mixture

• To lubricate the engine's moving parts

• To filter the engine oil

Why is regular maintenance of spark plugs important?

• To ensure optimal fuel efficiency

• To reduce the engine's power output

• To increase the engine's oil consumption

• To decrease the vehicle's top speed

What does the term "spark plug gap" refer to?

• The distance between the spark plug and the engine

• The length of the spark plug

• The distance between the spark plug's electrodes

• The width of the spark plug's thread

What can happen if the spark plug gap is not set correctly?

• The engine will produce more power

• The spark plug will last longer

• The engine may run rough or misfire

• The fuel efficiency will increase

Which of the following is NOT a type of spark plug?

• Copper

• Gold

• Platinum

• Iridium

What role does the spark plug gap play in engine performance?

• A larger gap increases fuel consumption

• A smaller gap can lead to unburnt fuel in the exhaust

• The correct gap ensures optimal combustion

• The gap size is irrelevant to engine performance

What is a common symptom of spark plug issues?

• Increased acceleration

• Louder music from the stereo

• Engine misfiring

• Smoother gear shifts

How does a spark plug directly affect a vehicle's fuel economy?

• By increasing air intake

• By ensuring efficient combustion of fuel

• By reducing exhaust emissions

• By cooling the engine faster

What is the consequence of having a spark plug gap that is too wide?

• Increased fuel efficiency

• Decreased risk of engine knocking

• Potential for spark misfire

• Longer spark plug lifespan

What is NOT a benefit of replacing spark plugs at recommended intervals?

• Improved fuel economy

• Enhanced engine performance

• Reduced exhaust emissions

• Increased oil consumption
