In previous articles we have tried to outline general characteristics, peculiarities, types and functioning of the ignition cable. As a matter of total clarity, it seems appropriate to clarify some points.
First point: What is an ignition cable?
Technically, the ignition cable has a real high voltage cable with the important function of connecting the ignition coil to the pipettes, two other essential components of the engine. The ignition cable is therefore a communicator that carries the signal to the engine so as to allow it to start.
Second point: When should an ignition cable be replaced?
Furthermore, the ignition cable is extremely important when considering fuel consumption. This, in fact, the more it wears, the more it increases fuel consumption, so it is good to consider that the average life of a standard ignition cable is about 50,000 kilometers. Of course, this is an approximate and highly variable figure since it varies according to the type of route that is generally taken with the car. Its replacement is, then, to be taken into consideration not only if linked to energy waste but also because a worn ignition cable, in the long run, could damage the upstream carburetion system.
Third point: How is an ignition cable composed?
However simple it may appear, the ignition cable enjoys an extraordinary charm for the way it is composed and although it may appear rustic to us, its extraordinary nature lies precisely in this characteristic. Generally, an ignition cable has a centered internal core generally made up of a good conductor. In most cases, its internal part is made up of copper, which, presenting itself as an excellent conductor and at a good price on the market, is very suitable for the task assigned to it. Moving on to its coating, and therefore the outermost part, this is generally composed of an insulator and usually silicone is used to shield the passage of electricity inside it. But the use of silicon, or rather the insulator, not only serves to insulate the internal copper, but also and above all to give solidity and strength to the ignition cable itself. From the point of view of its characteristics, this is highly resistant to high temperatures and corrosion by chemical agents external and internal to the car engine.
