Quiz on Ignition Systems

What are the three conditions that must be met for a gasoline internal combustion engine to run at maximum efficiency?

• Good air fuel mixture, low level of compression, weak sparks

• Poor air fuel mixture, low level of compression, optimal timing and powerful sparks

• Good air fuel mixture, high level of compression, optimal timing and powerful sparks

• Poor air fuel mixture, high level of compression, weak sparks

What is responsible for optimal ignition timing and powerful sparks in an ignition system?

• Spark plugs

• Distributor

• Ignition coil

• Igniter

How is high voltage generated from a 12-volt power source in an ignition system?

• By directly converting the voltage

• By using conductive breaker points

• By using a mechanical advancer

• By utilizing self induction and mutual induction effects

What is the role of a transistor in a transistorized ignition system?

• To adjust the spark plug gap

• To generate sparks

• To control the primary current in the ignition coil

• To regulate the air fuel mixture

How is ignition timing controlled in an engine according to the text?

• By altering the air fuel mixture

• By changing the spark plug heat range

• By increasing the compression pressure

• By adjusting the ignition advance angle

What is the purpose of a vacuum advancer in an ignition system?

• To control the ignition advance angle

• To regulate the air fuel mixture

• To adjust the spark plug gap

• To control the primary current
