The ignition coil is an extremely important component of the entire engine ignition system. This solution is used in gasoline engines with spark ignition. 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, the entire ignition system would short-circuit and fail. How does the ignition coil mechanism work?

The ignition coil

A magnetic field is generated when the circuit is closed. The coil produces an induced voltage. Upon ignition, the magnetic field is interrupted and a high inductive voltage is generated. The voltage jump takes place at the spark plug, which allows the current to flow freely. The fuel-air mixture is ignited by the flashover spark. In other words, the fuel combustion processes needed to run the vehicle are activated.

In older car models, the ignition coil is susceptible to numerous damage with age. One of the symptoms of a system's deterioration may be problems with starting the engine. The ignition coils should be checked from time to time to replace this component in time. In the event of a sudden breakdown, the car is of course immobilized and the engine loses its ability to continue working. In such a situation, repairing the ignition coil is virtually impossible or is pointless due to the very high cost. A better solution is to buy a used item.

In the "Ignition Coil" category below, there are proven used parts from well-known manufacturers such as: Bosch, Denso, Valeo or Delphi. A wide selection allows you to choose the ignition coil used for many car models. Of course, all parts have been thoroughly checked for functionality. You get a boot warranty when you buy it. Attractive prices are a big advantage, as they will allow you to repair the ignition system in a cheaper way.
