An ignition system is a system in an internal-combustion engine that generates a spark to ignite the fuel-air mixture. It includes the battery, ignition coil, distributor, spark plugs, and associated switches and wiring.  The purpose of an ignition system is to generate a very high voltage from the car's 12-volt battery and send it to each spark plug in turn, igniting the fuel-air mixture in the engine's combustion chambers. The burning of this mixture in the cylinders produces the motive force.  There are three basic types of automotive ignition... Show more

An ignition system is a system in an internal-combustion engine that generates a spark to ignite the fuel-air mixture. It includes the battery, ignition coil, distributor, spark plugs, and associated switches and wiring. 

The purpose of an ignition system is to generate a very high voltage from the car's 12-volt battery and send it to each spark plug in turn, igniting the fuel-air mixture in the engine's combustion chambers. The burning of this mixture in the cylinders produces the motive force. 

There are three basic types of automotive ignition systems:
Distributor-based
Distributor-less
Coil-on-plug (COP) 

Here are some types of ignition systems:
Battery ignition system: Relies on an electrical power source, usually a lead-acid battery, to generate the high-voltage sparks needed to ignite the fuel-air mixture within the engine cylinders.
Magneto ignition system: A magneto is responsible for creating high-voltage energy, which generates electricity that helps a vehicle run. For example, a distributor and a generator are built as a single unit in a magneto ignition system.
Inductive discharge system: Consists of a magnet on the flywheel that passes by a fixed electrical coil. The electrical coil is connected to one or two spark plugs, often through a transformer (to boost the voltage) and/or an interrupter (to control the timing).
