Differentiate Between Different Types Of Ignition Coils

　　Although all ignition coils have the same working principle, over the past few decades, different types of ignition coils have been developed. This means that the type of ignition coil your vehicle uses depends on when it was manufactured. Let's take a look at the different types of ignition coils

　　Canister ignition coil

　　This type of ignition coil has been in use since the early 1900s, but you can find it on classic cars today. Some older models have an oil-filled housing that cools and insulates the iron core and primary and secondary coils.

　　distribution coil

　　The distributor mechanism is used to supply the spark plug with the high voltage current produced by the ignition coil.

　　ignition block

　　An ignition block consists of several ignition coils that are connected to the spark plugs by HT cables. Ignition blocks can be made using either single spark technology or dual spark technology.

　　If the vehicle is equipped with a single spark ignition block, all ignition cables supply high voltage to only one cylinder. Dual spark technology is designed to send high voltage current to two cylinders, one on the power stroke and the other on the exhaust stroke.

　　pencil ignition coil

　　Typically used on vehicles with electronic ignition systems, the pencil ignition coil is mounted directly on the spark plug. In this way, when the pencil ignition coil is placed in the spark channel, power is fed directly to the spark plug, eliminating power losses.

　　ignition coil set

　　A coil set consists of several pencil ignition coils mounted on rails that span several spark plugs.
