The distributor handles several jobs.
Difference ignition coil distributor cap.
Older cars used the distributor cap and rotor to distribute the spark made by the coil to the proper cylinder.
Choosing the correct ignition coil.
Hey guys i need to find replacement ignition parts for my 3000gt vr4 and i was looking at these coils.
Remove the distributor cap screws remove the cap and you will see the coil.
General motors changed to their coil in the cap electronic ignition in 1975.
I have a 1954 ford with a 272 y block.
The coil on plug cop vehicle ignition system incorporates all the electronic controls found in a dis car ignition system but instead of two cylinders sharing a single coil each cop coil services just one cylinder and has twice as much time to develop maximum magnetic field.
The coil is connected to the rotor which spins inside the cap.
While this is called a conventional ignition system it s something of a misnomer.
It takes an ignition village.
The ignition coil is inside the distributor behind the cap.
Standard socket distributor cap type hei distributor cap recessed pin distributor cap external pin post distributor.

Newer cars use a dis distributorless ignition system a seperate coil for each cylinder on the engine which alows a greater dwell time for the charge to build up in the coil this creates a hotter spark and increased burning of the fuel air mixture and therefore lower emissions.
Whats the difference between performance ignition coils and regular ignition coils.
Its first job is to distribute the high voltage from the coil to the correct cylinder.
This is done by the cap and rotor.
In sum to achieve maximum performance the coil should be optimized for the type of ignition system employed inductive or capacitive discharge and distributor s.
