Ignition is defined as?

• A. A battery-powered coil system.
• B. An automatic, intermittent duty, AC powered capacitor discharge system.
• C. A simple electrical spark device.
• D. A mechanical crank-start system.

Answer: (B)

Ignition is the system that provides a timed, high-energy spark to ignite the air-fuel mixture in the engine. The best description here is an automatic, intermittent-duty system that uses capacitor discharge to generate the spark, powered by an AC source to charge the capacitors. The energy stored in the capacitor is released quickly through the ignition coil and spark plug at the right moment, giving a strong, reliable spark each cycle. This distinguishes it from a simple battery-powered coil arrangement or a basic spark device, which don’t capture the same timed, high-energy discharge in the same automatic fashion. It also isn’t a mechanical crank-start system, which is used for starting the engine rather than providing normal ignition during operation.
