Ignition Coil: Description and Operation
Ignition Coil Pack
Coils are mounted together in a coil pack. These ignition coil packs are triggered by the Distributorless Ignition System (DIS) module and are timed by
the Electronic Control Assembly (ECA). Each coil pack contains separate ignition coils. The ignition coil fires two spark plugs simultaneously, one on
the compression stroke and one on the exhaust stroke. The spark plug fired on the exhaust stroke uses very little of the ignition coil's stored energy. The
majority of the energy is used by the spark plug on the compression stroke. Since these two spark plugs are connected in series, the firing voltage of one
plug will be negative with respect to ground, while the voltage of the other will be positive in respect to ground.
