What is Ignition Distributor System?

       The ignition distributor handles several jobs. Its first job is to distribute the high voltage from the coil to the correct cylinder. And the coil is connected to the rotor, which spins inside the cap. The rotor spins past a series of contacts, one contact per cylinder. As the tip of the rotor passes each contact, a high-voltage pulse comes from the coil. The pulse arcs across the small gap between the rotor and the contact (they don't actually touch) and then continues down the spark-plug wire to the spark plug on the appropriate cylinder.

       The engine is like a big pump. It pumps air and gas in, then pumps exhaust out. The byproduct is a lot of energy that is sent to the wheels and exhaust out the tailpipe. That's the basic of all basic descriptions. Engine mixes air and fuel, then adds a spark to make the explosion. This spark ignites the air-fuel mixture, and is referred to as the ignition. This ignition takes place thanks to a group of components working together, otherwise known as the ignition system. The ignition distributor system consists of an ignition coil, distributor, distributor cap, rotor, plug wires and spark plugs. Older systems used a points-and-condenser system in the distributor, newer ones use an ECU, a little brain in a box, to control the spark and make slight changes in ignition timing.
