In order to discharge in an internal combustion engine with a spark plug, a high voltage of 20,000 - 35,000 V is required. Ignition coil is a type of transformer that converts 12V battery voltage to the high voltage required for spark plug discharge. Basically consists of a primary coil and secondary coil core (iron core), between these components are filled with epoxy resin to ensure insulation.
The ignition coil may deteriorate or fail. Does not turn up when accelerated Not easy to start engine. Unstable idle Engine check (MIL) light up.
(Replace the ignition coil) A comfortable running back. Stable idling Improved fuel economy.
■ We recommend replacing the whole cylinder when replacing the ignition coil. If the ignition coil failure is found in one cylinder, the ignition coil on the other cylinder may deteriorate and may cause premature failure, so we recommend replacing the whole cylinder.
■ We also recommend checking the spark plug when replacing the ignition coil. Continuing to use worn out spark plugs will increase the voltage requirements and strain on the ignition coil. Check the spark plug when replacing the ignition coil as it may cause breakdown.
