IGNITION COIL [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5]

id0118i2000100


Purpose, Function

•  The ignition coil generates high voltage required for ignition by electromagnetic induction.
•  The direct ignition system stabilizes the spark plug ignition performance by transmitting the high voltage generated in the ignition coil directly to the spark plug, which suppresses the decrease in voltage.
•  The ion sensor is built into the ignition coil IC igniter.
The ion sensor detects pre-ignition. For the ion sensor, refer to the CONTROL SYSTEM. (See ION SENSOR [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].)

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. (See ION SENSOR [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].)

Operation

•  Current to the ignition coils is blocked and high voltage is generated at the optimum timing according to the driving conditions by the PCM ignition control.
