Ignition System Quiz

What is the voltage of the low tension (LT) circuit connected to the car's main electrical system?

• 6V

• 12V

• 24V

• 48V

What happens when a spark is required in the ignition coil operation?

• The magnetic field collapses suddenly

• The magnetic field builds up slowly

• The magnetic field remains constant

• The magnetic field disappears

What is induced in the secondary winding when the magnetic field collapses?

• A current

• A voltage

• A resistance

• A capacitance

What is the main difference between the primary and secondary windings in the ignition coil?

• The primary winding has more turns

• The secondary winding has more turns

• Both have the same number of turns

• The primary winding is thicker

What is the role of the condenser in a contact breaker ignition system?

• To energize the primary coil

• To reduce arcing

• To rotate the rotor arm

• To distribute the spark

What does arcing between the contact breaker points cause?

• Increased power

• Erosion of points

• Better timing

• Reduced voltage

What surrounds the central copper electrode in a spark plug?

• Rubber insulator

• Plastic insulator

• Aluminum oxide insulator

• Steel insulator

What does the ECU in fully electronic ignition systems store?

• Data about fuel consumption

• Data about correct ignition timing

• Data about engine temperature

• Data about vehicle speed

What is the function of the coil pack in distributorless ignition systems?

• Supplies spark plugs for pairs of cylinders on opposite strokes

• Controls the fuel injection

• Monitors engine temperature

• Stores data about ignition timing

On some engines, where is the coil pack mounted?

• On the spark plug

• On the distributor cap

• Remotely and connected to the spark plugs using separate leads

• On the battery
