• The phase difference in the circuit of the two stator coils causes the electromagnetic pull between the rotor and
the stator to be eliminated logically. Due to this, electromagnetic vibration and generator operation noise
(electromagnetic noise) have been reduced.
• The pulsation occurring through voltage rectifying
is minimized, as a result, stable voltage output is
supplied due to the adoption of two stator coils
with the phase difference.
• The generator warning light in the instrument cluster illuminates under the following conditions.
— Charging system voltage problem
— Charging system voltage low
— Charging system voltage high
— IAT sensor circuit low input
— IAT sensor circuit high input

Construction
• Direct ignition coils installed directly to each spark plug have been adopted. By adopting direct ignition coils,
high-tension leads have been eliminated in order to simplify the parts of the ignition system, preventing voltage
reduction, and improving the firing efficiency.
• Independent firing control has been adopted to eliminate firing without spark, increasing firing energy.
• The direct ignition coil consists of an ignition coil, ignition coil connector, and boot area, which has the same
function as the current high-tension lead.
• The igniter has been integrated into each ignition coil.
Operation
• The firing timing of the coil is controlled by the PCM for optimum ignition timing control.
