Ignition coils
A
The ignition coil converts the low-voltage electricity of
the primary winding into the high-voltage electricity of the
secondary winding, and generates sparks through the
discharge of the spark plug to ignite the fuel-air mixture in
the gas cylinder.
The ignition coil is installed on the engine. Remove the
seat cushion to see the ignition coil installed on the
engine (see

in the fi gure below).
Working principle
The ignition coil is composed of a primary winding, a
secondary winding, an iron core, and a shell. When the
battery voltage is applied to the primary winding, the
primary winding is charged. Once the ECU cuts off the
primary winding loop, the charging is stopped and high
voltage is induced in the secondary winding. There are
three pins on the low voltage side of the ignition coil:
