Ignition Coil: Description and Operation

Ignition Coil

Ignition coils are made integral with an ignitor. The ignition system is of a dual-ignition-coil design, each coil causing two plugs to generate sparks
simultaneously.In response to the signal from the ECM, the ignitor supplies current to an ignition coil and the ignition coil supplies high-voltage
current to a pair of spark plugs (#1 and #2 or #3 and #4) simultaneously.
