Ignition System

Does the conventional breaker-point ignition system use a mechanical distributor to direct high voltage to spark plugs?

• YES

• NO

Answer explanation

The conventional ignition system uses a distributor to route the high-voltage current to the correct spark plug at the right time.

What component in the conventional ignition system controls the timing of the spark?

• Spark Plug

• Breaker Points

• Battery

• Ignition Coil

Answer explanation

Breaker points open and close in sync with the engine’s rotation to control the timing of the ignition spark.

In a conventional ignition system, what happens when the breaker points open?

• Current starts flow

• The spark plug is removed

• The magnetic field collapses

• The battery discharges

Answer explanation

• When the points open, current stops flowing in the primary circuit, causing the magnetic field to collapse and induce high voltage in the secondary coil.

Which part stores energy and helps prevent arcing in a conventional ignition system?

• Ignition Coil

• Condenser

• Rotor

• Spark Plug

Answer explanation

The condenser absorbs excess energy and prevents arcing at the breaker points when they open.

Is the ignition coil responsible for converting low voltage into high voltage?

• Yes

• No

Answer explanation

The ignition coil functions like a transformer, converting the battery's 12 volts into thousands of volts needed to fire the spark plugs.

What replaces the breaker points in an electronic ignition system?

• Distributor

• Spark Plug

• Pickup Coil

• Rotor

Answer explanation

The pickup coil detects engine position and signals the ignition module electronically, replacing the mechanical breaker points.

Does the electronic ignition system still use a distributor?

• YES

• NO

Answer explanation

While the system is electronic, early versions still retained the mechanical distributor to route spark to the cylinders.

In a distributorless ignition system, how is spark plug timing controlled?

• Mechanical Timing Chain

• Carburetor

• Ignition Module and Engine Computer

• Breaker Points

Answer explanation

In DIS, timing is managed electronically by the engine control unit (ECU) and ignition control module, without a distributor.

Which ignition system eliminates the use of spark plug wires?

• Conventional

• Electronic

• Distributorless

• Compression

Answer explanation

In DIS, the ignition coil is mounted directly on the spark plug, eliminating the need for spark plug wires.

Which of the following is NOT a benefit of distributorless ignition systems?

• No timing adjustments

• Fewer moving parts

• Requires spark plug wires

• No distributor moisture problems

Answer explanation

DIS systems do not require spark plug wires, which is one of their main advantages.
