IGNITION COIL CONSTRUCTION/OPERATION[ZJ, ZY, Z6]

id0118b1100300


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, and also to prevent voltage reduction and improve 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.

Operation

•  The firing timing of the coil is controlled by the PCM by means of a built-in igniter for optimum ignition timing control.
