The ignition coil is an extremely important element of the entire engine ignition system. This solution is used in spark ignition gasoline engines. In fact, the mechanism consists of two coils: primary and secondary. In the middle there is a core on which the copper wires of both coils are wound. The wires are properly insulated and secured so that they do not come into contact with each other. Otherwise, there would be a short circuit and failure of the entire ignition system. How does the ignition coil mechanism work?

The ignition coil

When the circuit is closed, a magnetic field is generated. The coil produces induced voltage. At the moment of ignition, the magnetic field is interrupted, as a result of which a high induction voltage is generated. The voltage jump takes place on the spark plug, which allows the free flow of current. The ignition of the fuel-air mixture occurs during the flashover. In other words, the fuel combustion processes needed to drive the vehicle are activated.


In older car models, the ignition coil with age is susceptible to numerous damage. One of the symptoms of the inferior condition of the system may be problems with starting the engine. Ignition coils should be checked from time to time to replace this component in time. In the event of a sudden failure, the car is of course immobilized and the engine loses the ability to continue working. In such a situation, repair of the ignition coil is basically impossible, or it misses the target due to very high costs. A better solution is to buy a used item.

In the "Ignition Coil" category below, proven parts are available from well-known manufacturers such as Bosch, Denso, Valeo or Delphi. The wide selection allows you to select the ignition coil used for many car models. All parts have obviously been thoroughly checked for fitness. When you buy, you get a start-up guarantee. Attractive prices are a great advantage, which will make it possible to repair the ignition system in a cheaper way.

Ignition coils and modules

The ignition coil is the part of the combustion engine ignition system that is responsible for generating the high voltage needed to ignite the air-fuel mixture in the combustion chamber. The ignition coil consists of a core with a ferromagnetic core and a coil with a high-voltage wire. Both it and the entire ignition system play an important role in the vehicle, because without such a module it would not be possible to start the drive unit or the functioning of the engine would leave much to be desired.

A wide selection of coils and ignition systems

When the engine is running, the ignition system sends an electric current to the ignition coil, which induces a magnetic field in its core. When the current flow is interrupted, the magnetic field begins to decrease, which induces a very high voltage in the coil. This high voltage is then sent to the spark plugs to ignite the air-fuel mixture in the combustion chamber. In this way, it is possible to start the drive unit and its proper functioning.

Of course, like many other components, coils as well as entire ignition systems are subject to wear and failure, which can lead to ignition problems such as unstable engine operation, starting problems, loss of engine power and increased fuel consumption. In the event of problems with the ignition coil, it is recommended to use the services of car mechanics, which involve not only diagnostics, but also effective repair.
