Operation
This model uses the distributorless ignition system which mainly consists of ignition coils, spark plugs, etc.
Ignition advance angle is controlled by Engine Control Module (ECM) directly.
Ignition coil consists of two primary windings, two secondary windings, iron core, housing, etc. When the
primary winding is connected to ground, it is charged. Once ECM cuts off the primary winding circuit, charging
stops, and at the same time, a high voltage is induced in the secondary winding to enable the spark plug to
discharge. This ignition system's difference from the ignition coil with distributor is that a spark plug is
connected to the ignition coil secondary winding at each end, which makes two spark plugs ignite
simultaneously. Two primary windings turn on/off alternately. Two secondary windings alternately discharge
accordingly.
