Also referred to as a spark coil, an ignition coil is a type of electrical induction coil that is used to transform lower voltages of power to the higher voltages of power required to fire a system's spark plugs. Very similar to an electric transformer, ignition coils have both primary and secondary winding circuits.Even though they are used in larger, multi-part ignition systems, ignition coils can be considered the most essential component of the system. It would be ineffectual without both the high voltage and ignition energy provided by these specific electric coils. The most common application of ignition coils is in the automotive industry, in which they are used for vehicle ignition systems such as in cars, minivans, trucks, SUVs, motorcycles and more. Another common automotive coil is the choke coil, which is usually a part of an engine. However, ignition coils are also utilized in additional industries such as: industrial manufacturing, for material handling equipment such as forklift trucks and mobile overhead cranes; agriculture, for farming equipment such as tractors, combines and balers; and recreation, for off-road vehicles such as quads, dirt bikes, three-wheelers and golf carts. Ignition coils must not only be manufactured from conductive materials such as copper or silver, but must also be formed from materials offering high-temperature resistance.
