An alternator is an essential component of a vehicle’s electrical system. Its primary function is to convert mechanical energy from the engine into electrical energy. This transformation is crucial as it powers various electrical systems in the vehicle, including headlights, dashboard lights, and the battery. The alternator operates when the engine runs, taking advantage of the engine’s mechanical energy to produce electric current, typically in AC form, which is then converted to DC for use by the car’s electrical systems.

Though not technically a type of timing belt, timing chains are worth mentioning as they serve the same purpose. Timing chains are made of metal links and tend to last longer than rubber timing belts. They do not require regular replacement like rubber belts, as they are less prone to stretching and wear. However, they can be noisy and heavier, potentially impacting engine performance. Timing chains are typically found in larger engines, where the robustness of a chain is beneficial.
