Ignition Coil: Description and Operation
Ignition Coil
PURPOSE
The Ignition Coil Pack is controlled by the Powertrain Control Module (PCM) to provide secondary spark at the correct time in the combustion
process.
OPERATION
-
Each ignition coil fires two spark plugs simultaneously, One on the compression stroke. This spark plug uses the majority of the ignition coil
stored energy.
-
One spark plug fires on the exhaust stroke. This spark plug will use very little of the ignition coils energy.
-
These two spark plugs are connected in series, so the firing voltage of one spark plug will be negative with respect to ground, and the other will be
positive with respect to ground.
CONSTRUCTION
The Ignition Coil Pack contains three separate ignition coils.
