Kia Picanto: Ignition System / Ignition Coil
Kia Picanto JA 2017-2022 Service & Repair Manual / Engine Electrical System / Ignition System / Ignition Coil
Description and operation
| Description |
An
ignition coil is an induction coil in an engine's ignition system which
transforms the battery's low voltage to the high voltage needed to
create an electric spark in the spark plugs to ignite the fuel. Coils
have an internal resistor while others rely on a resistor wire or an
external resistor to limit the current flowing into the coil from the
battery 12 V supply.
