Common Ignition Coil types for cars
The Ignition Coil on gasoline engine cars has an important function so that the engine can start and work normally. The ignition coil becomes a source of high voltage electricity so that sparks can be created at the spark plug so that the combustion process in the combustion chamber can occur.
Along with the development of ignition system technology in vehicles, the ignition coil has also experienced many changes, mainly if you have discussed the ignition system used in the car.
Examples are the conventional type ignition system, semi transistor ignition system (CDI), or Distributor-less ignition system.
Each ignition system requires a different type of ignition coil. Here we will inform you about the Ignition coil types and models in the car.
1. Can Conventional Ignition Coil (Tube type coil)
This type of ignition coil is a type of coil that is quite popular and widely used, especially in conventional ignition systems or semi-transistor ignition systems. This ignition coil is usually used to serve all the spark plugs in the engine cylinder. That is one coil for many spark plugs.
A conventional ignition system that uses the Can Conventional Ignition Coil also requires a distributor as a component that will be directing high voltage electricity to each spark plug.
The tube coil is shaped like a large tube, with a large voltage of 20,000V. The dimension factor (the size and weight of the tube) makes this type of ignition coil no longer used in modern cars.
2. Molded Ignition Coil Type
Molded Ignition Coil Type is an ignition coil currently the most widely used by modern cars. Named Molded Ignition Coil Type because of its shape, which is wrapped by a special resin that resembles wax but is very resistant to heat and high voltage.
It is needed because some types of Molded Ignition Coil can produce a high voltage of up to 40,000 V in each ignition coil. Here are some types of Molded Ignition coil that we know
A). Single Coil Pack
Single Coil Pack Ignition Coil is a molded type ignition coil used in ignition systems with distributors (conventional and semi-transistor).
This Single Coil Pack Ignition Coil replaces the Can Conventional Ignition Coil (Tube Coil), which means that this type of coil is also used to serve multiple spark plugs depending on the number of cylinders owned by the engine.
There are Ignition coil types installed directly into the distributor. Some are installed outside the distributor, depending on the needs of the engine model used.

B). Ignition Coil On Plug (Single Spark Coil)
Ignition Coil On Plug has another name, also often referred to as single spark coil or pencil coil because its shape is like a pencil.
Ignition Coil On Plug is a type of coil currently widely used in today's modern cars, more precisely for cars that already use a Direct Ignition System (Ignition system without a distributor).
Ignition Coil On Plug (Single Spark Coil) is used for only one spark plug: the more spark plugs, the more Single Spark Coils are needed. This type of coil has a smaller, slender design and is generally placed directly above the spark plug hole.
C). Double Spark Coil
If the single spark coil is only used for one spark plug, the double spark coil is used for two spark plugs, meaning that one coil serves two spark plugs. Therefore, the Double Spark Coil can provide an output voltage of up to 40,000V.
As a result, using high-quality resin and materials makes this type of double spark coil more expensive than other types of coils. This Double Spark Coil is also used specifically for cars whose ignition system has adopted a distributor-less ignition system.
