What Is An Ignition System?

A vehicles ignition system consists of several components that need to work together, controlled by the vehicle’s  computer, to get your auto started. Starting with the ignition coil, power is taken from the battery and turns it into a spark powerful enough to ignite the fuel vapor. The vehicles coil is made up of two windings called the primary and secondary. The primary winding collects power and creates the spark, while the secondary circuit sends it to the distributor. The distributor is a precise spinner which distributes the sparks via the spark plug wires to the vehicles individual spark plugs with precise timing by using a rotor. The vehicles spark plugs are plugged into the cylinder head. When the vehicles intake valves have let the proper amount of fuel and vapor into the cylinder, the spark plug provides a hot spark which ignites, creating combustion.
