IGNITION COIL CONSTRUCTION/OPERATION [L8, LF, L3, L3 Turbo]
id0118a4100300
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.
