Hyundai Santa Cruz: Ignition System / Description and Operation
- Description
The ignition coil is a kind of small transformer that transforms the
battery voltage to 30 kV or more to create a spark in the spark plug gap
in the cylinder.The igniter embedded in the ignition coil includes the
power transistor and it is an electronic switch whose electric current
is controlled by the Engine Control Module (ECM) signal. The ignition
timing is controlled by the ECM and the standard ignition timing data
depending on the engine operating condition is stored in the ECM
memory.The engine operating conditions (speed, load, warm-up state,
etc.) are detected by the various sensors.Based on these sensor signals
and the ignition timing data, when the ECM applies the ignition signal
to the ignition coil for a certain period of time, igniter is energized
and current flows and rises gradually to the primary coil and the
magnetic filed is produced.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.
