Ignition timing refers to the precise moment when the spark plugs in an internal combustion engine ignite the air-fuel mixture within the cylinders. Adjusting ignition timing involves altering the timing of this spark to optimize engine performance, fuel efficiency, and emissions.
Correct ignition timing ensures that the air-fuel mixture combusts at the optimal point in the engine’s cycle, maximizing power output and minimizing harmful emissions. It also helps prevent engine knocking, which can damage engine components. Historically, ignition timing was adjusted manually using a distributor, but modern vehicles use electronic engine control units (ECUs) to manage this process.
