Role of the Distributor

The distributor functions as a critical component in traditional ignition systems, primarily managing the distribution of high-voltage electric current to each cylinder’s spark plug. By performing this role, it ensures that the engine receives the necessary spark at precisely the right moment during the combustion cycle.

The operation of the distributor is facilitated through a set of moving parts and contacts. Key components include the rotor, which spins and directs the electrical charge toward the correct terminal, and the distributor cap, which houses the terminals connected to each spark plug. This coordinated action allows for the ignition of the air-fuel mixture in an orderly sequence.

A properly functioning distributor is vital for optimal engine performance. It helps maintain ignition timing and optimizes the combustion process, thus enhancing fuel efficiency and engine power. Without this device, the engine would struggle to fire correctly, resulting in misfiring and decreased performance.
