CAR Ignition coil

Ignition coil: common defects and their signs

  1. Overheating
    • Troubles occur during engine start, sometimes it doesn’t start at all.
    • Engine operation is unstable at idling.
    • Engine power lowered and fuel consumption increased.
  2. Short circuit in winding
    • Engine operation is unstable, especially in cold or moist weather.
    • “Check Engine” indicator activates on the dashboard.
    • Failures in engine operation occur at sharp accelerator pedal pressing.

How to repair ignition coil?

If the part is broken down it should be replaced immediately. Driving with a defective ignition coil may lead to engine overheating, which is quite negative for the car. Replacement of the ignition coil can be performed by your own, but only if car servicing works experience is present. Otherwise it is better to contact a service station. The component replacement algorithm is following:

  1. Turn off ignition and wait for the engine to cool down.
  2. Cut off power supply from the battery.
  3. Disconnect the wires coming to the ignition coil from it. Remember or mark their position, in order to avoid mistakes at installation.
  4. Unscrew the nuts fastening the coil, pull it and remove from the housing.
  5. Install a new component, fix it with the help of nuts and connect the wires.
  6. Mount the negative terminal to the battery.

Turn off the ignition in the car before servicing.
Disconnect the cable from the negative terminal of the battery.
Carefully inspect spark plugs, their wells and terminals while replacing the ignition coil.
Use special tools to keep the replacement of the ignition coil convenient and safe.
Try to remove the part carefully in order to avoid damaging the ignition coil plug.
Average service life: 110 000–140 000 km.

Ignition coil Information

Ignition coil is a component of the ignition system, which is used to convert low voltage coming from the battery or generator to high voltage. The coil is a transformer with a high rate of transformation. When transformation ratio increases, voltage in the secondary winding also is increased. At the same time overall dimensions also increase.

Moreover, the secondary coil should have characteristics that provide the necessary current, peak voltage and spark duration. It must rapidly charge for subsequent return of voltage to the spark plugs. There are three types of ignition coils. For one spark, where the system exists without ignition distributor, ignition coil is one –spark type. The main requirement for this part is quick charging. It is important for transmission of voltage to the spark plug, which is important at high speeds of the crankshaft. Ignition coils with oil or bitumen coating in metal housing are increasingly replaced by the coils with fillings of epoxy resin.

These coils provide greater flexibility in the choice of geometric dimensions (can be smaller), types and number of electrical terminals. They are more resistant to vibration and have a small mass.

Even distribution of load between the insulating elements with high dielectric resistance provides a compact coil size, where insulating layers of foil and paper are placed between layers of wire. Self-capacity of the coil is also reduced. Ignition coil for one and two sparks are used as an alternative to conventional systems with the ignition distributor. These coils are used in systems without ignition distribution.
