IGNITION COIL CONSTRUCTION/OPERATION[LF, L3]

id0118b2100300


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.
