The Dodge distributor cap is an important component in the ignition system, helping to deliver high voltage spark to the engine cylinders. The combustion process that produces the power of the engine requires three crucial ingredients. These are oxygen and fuel, delivered to the cylinder in a balanced mixture, and high voltage spark to ignite this mixture in the engine combustion chambers, beginning the combustion process. The high voltage spark is produced by the coil, and then transferred via a heavily insulated high voltage wire to the distributor. The distributor must then transmit the voltage on to be carried through to the engine. This job is done by the Dodge distributor cap and rotor. The distributor rotor is mounted on the center shaft of the distributor where it spins inside the Dodge distributor cap, passing a number of electrical contacts as it rotates, one for each engine cylinder. As the rotor tip passes each contact, a burst of high voltage power is released by the coil to arc across the rotor tip to the contact. After transmission to the contact, the voltage travels through the spark plug wires to the spark plug installed at each engine cylinder. The spark plug uses the voltage to ignite the fuel and mixture in the engine combustion chamber. The Dodge distributor cap needs to be replaced periodically to continue its effective function, generally done at the regular vehicle tune-up.
