The Isuzu distributor cap is an important ignition system component, helping to carry spark to the engine. Your engine needs a well-balanced and precisely timed combination of three crucial ingredients to produce smooth and efficient power from the combustion process. These ingredients are oxygen and fuel, delivered to the combustion chamber in a well-balanced mixture, and high voltage spark, transmitted through the spark plugs to each of the engine cylinders to ignite the fuel and air in the combustion chambers. The Isuzu distributor cap performs a step in the process that carries this high voltage spark to the spark plugs, enabling them to contribute to the combustion process. The high voltage used for this process is produced by the coil, which transmits it to the distributor through a highly insulated high voltage wire. The distributor will then pass the high voltage on to the spark plug wires through a series of electrical contacts, using the Isuzu distributor cap and rotor to complete this transfer. The distributor rotor is mounted to the center shaft of the distributor, spinning inside the Isuzu distributor cap. The rotor passes these contacts as it rotates, sending a burst of power emitted by the coil to each one in turn, arcing over the rotor tip to the contact. As this high voltage reaches the contacts, it is transmitted through the spark plug wires to the spark plugs. This process will cause a gradual accumulation of wear on the Isuzu distributor cap, making its regular replacement necessary.
