The Jeep distributor cap is important to the proper function of your vehicle, helping to carry the spark to the engine to contribute to the combustion process. The ignition system is vital to the combustion process, delivering the high voltage to the spark plug at each engine cylinder, giving it the power to add a high voltage spark to the fuel and air mixture in the combustion chamber, causing this mixture to ignite, beginning the combustion process. The voltage is delivered to the distributor from the coil through a highly insulated connection, to be passed on through the ignition system. This is accomplished by the Jeep distributor cap and rotor. The rotor spins on the center shaft of the distributor, inside the Jeep distributor cap. As it rotates, the rotor passes a series of electrical contacts, each one meant for the transmission of voltage to one engine cylinder. As the rotor spins into alignment with each contact in turn, the coil sends a burst of high voltage to arc across the rotor tip to the contact. After the power reaches each contact it will travel along the spark plug wires to the spark plug. This process must be efficient and precisely timed to produce the best engine combustion, optimizing the power and performance of the engine. The Jeep distributor cap requires replacement at regular intervals to maintain the efficiency of the ignition system, most commonly done during the routine tune-up of the vehicle.
