Mazda CX-5 Service & Repair Manual: Ignition Coil [Skyactiv G 2.0]

Mazda CX-5 Service & Repair Manual / Electrical / Ignition / Ignition Coil [Skyactiv G 2.0]

Purpose, Function

The ignition coil generates high voltage by electromagnetic induction to discharge the spark plug.

Construction

The ignition coil is installed to the upper part of the spark plug (direct ignition coil).
With the adoption of the direct ignition coil, the ignition system parts have been simplified. As a result, voltage decrease is suppressed and ignition performance for the spark plug is stabilized.
The ignition coil is built into the igniter and ion sensor. For the ion sensor, refer to CONTROL SYSTEM..

Operation

Optimum ignition timing is performed according to the driving conditions by integrating the ignition control function into the PCM.
