Which ignition arrangement is used on a small engine without a battery?

  • A.A capacitor discharge unit only
  • B.A flywheel generator supplying a conventional coil, which is the arrangement used on every small engine today
  • C.A magneto
  • D.A coil ignition system, which draws its supply from the alternator and therefore requires no battery at all

Answer: C

A magneto generates its own energy from a rotating magnet and needs no external supply, which suits mowers and chainsaws. Flywheel generators feeding a coil are genuinely used and are closely related, which makes the last option a real arrangement. The shared behaviour explains why these belong together and the differences explain why both exist. Tracing the requirement back to the physical constraint that produces it makes the answer follow.
