Hyundai Santa Fe: Ignition Coil / Description and operation
The ignition coil is mounted on the top side of the cylinder head cover end.
The ignition coil consists of the primary coil that receives battery power and
the secondary coil that generates high voltage.
When the current in the primary coil is cut off by the ignition signal of the
ECM, the rapid change of the magnetic flux by the mutual induction action is
induced to the secondary coil and high voltage is generated depending on the
coil winding ratio.
This high voltage generated from the secondary coil is caught in the spark plug
gap and discharges as the electric field is destroyed to generate a spark.
