In the _________ ignition system, one coil fires all spark plugs.

In the _________ ignition system, one coil fires all spark plugs.

• A. Distributor
• B. Waste spark
• C. Coil-per-plug
• D. Capacitive discharge

Answer: (A)

In a distributor ignition system, one coil drives all the spark plugs. The coil generates the high-voltage pulse, and a rotor inside the distributor cap routes that pulse to each spark plug in the correct firing order. So despite there being one coil, every cylinder receives its spark when its turn comes, handled by the distributor’s rotation and cap connections. This is different from coil-per-plug (one coil per plug), waste-spark (one coil fires two plugs at once), or capacitor discharge setups that may be tied to distributorless configurations.
