Understanding Automotive Ignition Systems

What is the primary function of an ignition coil in an automotive electronic ignition system?

• To supply fuel to the engine

• To convert low voltage from the battery to high voltage needed to create a spark

• To regulate the engine temperature

• To control the exhaust emissions

Which of the following is a type of spark plug commonly used in modern vehicles?

• Copper

• Plastic

• Wood

• Glass

How does a distributor function in an ignition system?

• It mixes air and fuel for combustion

• It distributes high voltage from the ignition coil to the spark plugs

• It controls the oil flow in the engine

• It measures the speed of the vehicle

What is the purpose of timing adjustment in an ignition system?

• To increase the vehicle's speed

• To ensure the spark occurs at the optimal point in the engine cycle

• To reduce the engine noise

• To improve the vehicle's aerodynamics

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

• Iridium

• Platinum

• Steel

• Double Platinum

What component in the ignition system is responsible for adjusting the timing?

• Spark plug

• Ignition coil

• Distributor

• Fuel injector

In a distributor, what part is responsible for opening and closing the circuit to the ignition coil?

• Rotor

• Cap

• Points

• Condenser

What is the advantage of using iridium spark plugs over copper spark plugs?

• Lower cost

• Longer lifespan and better performance

• Easier to install

• More environmentally friendly

Which timing adjustment technique involves rotating the distributor to change the timing?

• Static timing

• Dynamic timing

• Vacuum advance

• Centrifugal advance

What is the typical voltage range that an ignition coil can produce to create a spark?

• 12-24 volts

• 100-200 volts

• 5,000-45,000 volts

• 1,000-2,000 volts
