In a low-tension ignition system, what is the role of the brush-type distributor?

• A. Distributes low voltage to each spark plug
• B. Increases fuel delivery
• C. Controls valve timing
• D. Flushes oil to the head

Answer: (A)

In a low-tension ignition system, the distributor’s job is to route the electrical energy to the correct spark plug at the right moment. A brush-type distributor uses carbon brushes and a rotating contact to pick up the low-voltage supply and connect it to the appropriate spark plug terminal as the rotor turns. This sequencing ensures the spark occurs in the proper firing order for each cylinder. It does not affect fuel delivery, valve timing, or oil circulation, which are handled by other systems.
