Ignition timing refers to the precise moment when the spark plugs in an internal combustion engine ignite the air-fuel mixture within the cylinders. Correct ignition timing is crucial for optimal engine performance, fuel efficiency, and emissions control. Misaligned ignition timing can lead to reduced power, increased fuel consumption, and potential engine damage.
Checking ignition timing involves verifying that the spark plugs are firing at the correct time relative to the piston’s position within the engine cycle. This timing is typically measured in degrees of crankshaft rotation before top dead center (BTDC), which is the point at which the piston reaches the highest point in the cylinder. The ideal ignition timing varies depending on the engine design and operating conditions.
